In short

The episode compares blackcurrants vs grape “purple” flavors across the US/UK, explains why blackcurrants were banned in the US (white pine blister rust), and then pivots to root beer’s origins and why it’s called “beer” despite being non-alcoholic.

Guests/backgrounds

Lily Hislop, a tree-crop breeder at the Savannah Institute in Wisconsin, works on breeding black currants. Greg Quinn, a currant farmer in New York who grows red and mostly black currants; he helped overturn New York’s blackcurrant ban.

Key claims

Blackcurrant flavor is common in Europe but rare in the US due to a 1911-era US eradication campaign against Ribes to protect white pine from white pine blister rust. Canada kept both by developing resistant varieties. In WWII, UK shortages boosted blackcurrant juice brand Ribena, shaping “purple” candy as blackcurrant in the UK; the US largely uses grape.

Notable examples

Skittles/Starburst “purple” taste test (UK blackcurrant vs US grape); Ribena’s vitamin C story; New York ban repeal after Quinn’s advocacy; Charles Hires’ sassafras-root “root tea” and later commercial root beer.

0:03My name is Rachel Brough and I live in Wichita, Kansas, and I was calling to ask some questions about root beer. So I don't drink alcohol, but I do love a root beer. And I was discussing this with a friend one day and we had so many questions. Yes, that's right. It's time once again for your listener questions. It's the summer edition of Ask Gastropod and we are Gastropod, the podcast that looks at food through the lens of science and history. I'm Cynthia Graber. And I'm Nicola Twilley. And once again, you have sent us down some very intriguing rabbit holes. Rachel got in touch about a drink you've probably never heard of unless you're American.

0:41Turns out even Americans are confused about it. Where did it come from? Why is it called beer if it's not alcoholic? What's the difference between root beer and sarsaparilla? Is ginger beer related? and why are there so many varieties that taste so different? I feel like they're all pretty different in their flavor notes. And listener Russell Taylor of Austin, Texas, wanted to know about blackcurrant, which is a flavor that many people in the world love, unless you are American, in which case you've probably never tried it. I've seen it only occasionally in things like, you know, relatively fancy imported preserves here, but in Europe, it's, you know, the default flavor.

1:22That's what purple is over there. just like grape in the U.S. So why is it common over there, fancy-seeming over here in the U.S., and why did this difference occur? Russell and Rachel, your wishes are our command. Stay tuned, and all will be revealed. This episode was supported in part by the Alfred P. Sloan Foundation for the Public Understanding of Science, Technology, and Economics. Gastropod is part of the Vox Media Podcast Network.

1:54One day, with the help of science, you might be able to live forever. Forever. Your body will just need a couple tune-ups. Injecting bone marrow in your 40s, your kidney in your 50s, your heart in your 60s, and so on. And then potentially a whole body transplant by the time that you were 90. This week on Explain It To Me, the quest for longevity. Find new episodes Sundays wherever you get your podcasts. Okay. When I first came to the United States to study in my early 20s, many things shocked me. The fact that people said zero instead of not. The fact that no one understood I meant two weeks when I said a fortnight.

2:36And, of course, the purple candy. Skittles, Skittles, five-size candies, taste the rainbow, what fruit flavors. Skittles, taste the rainbow, what fruit flavor. Here in the U.S., Skittles comes in five flavors, lemon, strawberry, orange, lime, and grape. In the U.K., Skittles also comes in five flavors, lemon, strawberry, orange, lime, and blackcurrant. Blackcurrant, not grape. Yep, mind blown. Our Starburst, which, by the way, used to be called opal fruits, they also come in a range of fruity flavors, including blackcurrant. Whereas your Starburst, you don't even have a purple. You just have that dark red cherry one.

3:17When it comes to purple-flavored things, gum, fruit drinks, hard candy. If you buy it and it's purple in America, it's nearly always grape-flavored. And in England, it's basically always black currant, two countries separated by a common language and a purple fruit. I don't want to cast shade here, but it is actually kind of hard to find an American who even knows what a currant is. I saw one researcher give the ballpark estimate of 0.1%, like, might have tasted a currant. Lily Hislop is a tree crop breeder at the Savannah Institute, which is in Wisconsin. She works on breeding black currants.

3:51Now, there's always the little bit of confusion that I get with xantycurrants, because people are like, oh yeah, I have had them in scones and stuff. And xantycurrants are not the same thing as black currants. Xantycurrants are literally just raisins, but they're a particular kind of raisin. They are raisin made from Corinth grapes, which is a black, small grape that is grown in the Corinth region of Greece. At some point in the past to English ears, Corinth sounded like currant. So the little dried raisins from Greece became known as currants. And then when actual ribes fruits like black currants started to be grown more widely, they were also little round dark things that looked kind of like the little dried raisins.

4:32So people called them currants too. But they're not the same thing at all. So what is a black currant if it's not a dried grape from the Corinth region of Greece? They are a blackberry that's a very deep color that has almost like a galaxy-like quality because it has these little specklings. And it tastes kind of like a blackberry and a pine tree together. It has this deep, jammy, dark berry flavor and a little bit of like a resinous quality. And they're pretty tart, but they're very unique. Blackcurrants are just one currant in an extended family of fruity delights. They're all part of a plant family called ribes.

5:12There's also white currants and red currants, which are part of the same species. It's just a matter of pigmentation. Well, not just pigmentation. They do also taste different. I describe red currants as just pomegranates on a bush without all the work. It has that like beautiful zing and like kind of the big seeds that like is reminiscent of pomegranate. It's like the mouthwatering quality of it. Oh, I love red currants so much. White currants are a little sweeter and less tart than red ones. There's also pink currants for people who can't decide between red and white. And then there's the currants oversized relative, the gooseberry, which looks like a hairy grape and tastes tart and fruity and amazing in both pie and chutney form.

5:52And then there's probably between 250 and more than 300 species all over the world. And they're on every continent except for Antarctica. Historically, currants of all varieties have been foraged all over the world wherever they've been found. but Europeans have been particularly enamored of them. Black currants seem to have been cultivated intentionally in Russia as early as the 900s, and then they seem to have been popular around most of northern Europe by about the 1500s. That's when people started deliberately selecting plants with the biggest and tastiest fruits to grow in their own gardens, to harvest, and turn into jams and jellies and cordials and chutneys.

6:29My granny made jars of black currant jam for me every year when I was little. And it's a very good jam. It's like got a complexity to it that blueberry jam or like grape jam doesn't have. It's really delightful. It's got like such a bright tartness to it. European settlers brought a lot of their favorite crops with them to North America, including black currants and in fact currants of all varieties. Currants seem to have shown up in about the 1600s. And by the late 1800s, red currants, black currants and gooseberries, they were being grown all over the Northeast and upper Midwest. If we're lumping currents together with black currents and red currents, before the ban, there was about 7 ,400 acres of currents growing in the United States, including both black and red.

7:13And that's about on par with how many acres of blackberries are growing today. And in fact, New York State, prior to the ban in 1911, as states go, was the largest cultivator of currents. Although back then it was red currents. And again, people would cultivate it mainly for jams and jellies. Greg Quinn is a current current farmer in New York. He grows both red and black, but he grows far more black than red. But wait a minute, the ban? What is this 1911 ban that Greg and Lily are talking about? Books? Alcohol? Those have been banned, sure. But fruit? To understand where the black current ban came from, we have to talk trees, white pine trees in particular, which I promise is going to make sense in a minute.

7:56When the first settlers came over, the northeastern part of the United States, and by northeastern, I mean Michigan to Maine to Virginia, that whole swath of land was covered with ancient white pine trees. Pine trees that were 265 feet tall. Now, to put that into perspective, the largest redwood is 360 feet tall. So these were enormous trees. These humongous white pine trees were extremely useful for the early colonists. You simply cut down a white pine. It's softwood, so it's easy to get through. You chop off all the branches and you've got, you know, lots of boards. You can make wooden log cabins.

8:32You can make furniture out of it. It was great to burn because it had pitch. The white pine was so important that one of the first coins issued in the colonies was the white pine shilling. You know, these were really big deals. And of course, like most things that we got super enthusiastic about using in America, we used it up. We cut down so, so many of the white pines, particularly on the East Coast, like about 80 % of the trees in Vermont and nearly as many in New York state. We really went to town on them. And in the early 1900s, late 1800s, it seems like folks in New England decided that was a bad idea and maybe we shouldn't have done that.

9:08And there was demand for timber and for stabilizing the soils that were beginning to erode really dramatically in New England. And so in the late 1800s, the U.S. government formed what's today known as the U.S. Forestry Service. And the first business of the U.S. Forestry Service was to reestablish white pines. At the time, Europeans had a flourishing baby tree growing business. They could grow baby trees more cheaply than Americans. And so as the story goes, 10 million white pine seedlings were collected and sent to Germany, which had a very robust nursery infrastructure. They propagated them into seedlings, sent them back on ships.

9:48And these baby trees were planted across the Northeast. Great. But wait, there was a problem. These trees were infected with something called white pine blister rust. It's a plant fungus. So this fungus needs both pines and ribes to complete its life cycle. It spends some time on the white pines, making spores that then go to the black currents, and then making spores there that go back and forth. So you need both of them. This white pine blister fungus had been doing its thing across Asia and Europe forever, but it wasn't a super big deal until the American white pine came along. It's like a little inconvenient for a black currant.

10:23It gets these orange pustules that kind of look like Cheeto dust on the underside of the leaves, but it like kills pine trees really dead. Like 75 to 95 percent of stands just eradicated by this fungus. American white pines, that is. Europeans did have pine trees, plenty of them, but they'd evolved with the disease and so it didn't totally wipe them out. American white pines had no defense against this rust. Also, black currants are particularly susceptible to white pine blister rust, so when the two met, the American pine was kind of screwed. And remember, America had begun importing and planting out millions of baby white pine seedlings from Europe where the infection was raging.

11:02Big whoops. So in 1906, this fungus was first identified, and then they found it in a lot of other sites. And then they're like, oh, crap, this is going to be really bad. This was also a time when America was waking up to the fact that it was importing a ton of useful plants from all around the world. Listen to our episode about David Fairchild for more. But we realized that some of those plants brought diseases and pests with them. All of this came to a head when the Japanese government gave a gift of ornamental cherry trees to be planted in D.C., and all of them were infested with multiple different pestilent insects and had to be burned, which was a major diplomatic incident.

11:39And because this took place in our nation's capital, our nation's government paid attention to the problem, and they passed a Plant Quarantine Act in 1912. Which you can read all about in a certain book I co-authored, all about quarantine called Until Proven Safe. But the point is, the very first federal plant quarantine order in the United States was against white pine blister rust. White pine seedlings couldn't be imported until they were shown to be free of disease. The problem is that white pine blister rust doesn't show up till about three years after infection, so that wasn't an effective solution.

12:13But at the same time, the federal government also launched a ban against planting all ribes. They were particularly worried about black currants. And when that still wasn't enough, they decided to eradicate currants from the U.S. landscape altogether. Congress gave a bunch of money to the USDA, and their subsection about forestry. This was before the Department of Forestry was its own individual unit. And they formed a task force for eradicating ribes in general. And this included pulling out farmers' fields without compensating them. This included pulling people's plants out of their gardens.

12:48This included going through the forests and finding black currants and native currants and ripping those out with fire and herbicide. They hung the plants from trees to die. The native currents, though, those weren't actually a real problem. They don't transmit white pine blister rust as easily. But the government didn't much care. They were on an anti-ribes crusade. They used the Civilian Conservation Corps to do this effort. They used war internees from Germany and Italy. They used prisoners. They used immigrant labor from Mexico. They used high school students. In 1934, they had 11 ,000 employed eradicators.

13:25So, like, this is a huge effort. Which meant no more delicious black currants or, of course, red currants or gooseberries for the American people. You guys just gave up on currants to try to save the white pine. Maybe people didn't love black currants enough. Maybe we didn't have a large enough culture for it. But in Europe, they love black currants a lot. They do now. They did back then. And those little berries were more important than an imported American tree. They gave up American white pines and kept growing currants. Canadians were also faced with the current versus white pine dilemma. and they chose both.

13:58While the U.S. was really heavily investing in eradicating the currents, Canada took the opposite approach and went, oh, this disease is bad. Maybe we should learn more about it so we can stop it. And so they did a bunch of interesting research and they developed the first varieties that were resistant to white pine blister rust. Okay, so that's why we lost black currents in America but didn't lose them in Canada and Europe. But to explain the candy difference, we have to go back to England in the 1940s. During World War II, shipping between countries was disrupted. England had been importing citrus for its high levels of vitamin C, but suddenly they couldn't get it.

14:32But it turns out the black currants have much more vitamin C than oranges pound for pound, and black currants grow really well in England. They don't mind shade and cold. Now, there wasn't a lot of producers of current juice at the time, but a company, a small little pharmaceutical company called Beecham's, started to make juice, and they called it Ribena. after the botanical family of ribes, of course. And that's really what put currant juice and currants on the map. Go, go, go, go. Ribena's rich in vitamin C. Take a go. Ribena's fruity and black currant tea. Take a go. Stick in a store and you will see.

15:10Ribena, goodness, is ready to go. Go, go. Ribena, as you know, growing up in the UK, ribena's a big deal. I mean, everybody drank ribena. Everybody knows where Ribena is. Greg is correct. Ribena is everywhere in the UK. It's available in cartons and bottles and as a cordial to mix with water. It's in every newsagents and vending machine and supermarket. And it's not alone. There are all sorts of blackcurrant-flavored drinks. And candies. And here's where the great divide occurred. In the 1960s and 70s, when a lot of these new artificially-flavored fruity candies and treats were being invented, our countries went two different ways.

15:50That was around the time that we were really heavily, well, that we were starting to see the mass productions of food and the like kind of solidification of our flavor profiles for our countries. And so when we're inventing Skittles, the Skittle flavors are basically the same between the two nations, except the purple Skittle in the United States is grape and the purple Skittle in the UK and basically everywhere else is black currant flavored. And Lily's a fan. It's a better flavoring than grape is. It's a great one. It's so much more interesting. Bold words. I, of course, agree that the British blackcurrant version of purple candy is best, but I will acknowledge some bias.

16:32There's only one way to find out. Candy taste test. That's coming up after the break.

19:41All right, are we ready for today's blackcurrant taste test? We are absolutely ready. I mean, it's not actually a blackcurrant taste test. It's a purple taste test. Okay, we're tasting the color purple. We are indeed. It's the purple candy transatlantic taste test you've all been waiting for. We got hold of British Skittles and American Skittles and British Starburst and American Starburst, and then we recruited our long-suffering partners, Jeff and Tim, to make this scientific. I'm going to close my eyes and you are going to try me out on the Skittles and I'm going to guess which is which and then we'll do it with the Starburst.

20:17Skittles first, all right. The Americans in the movie theater-like box. Okay. And the British in the little plastic bag.

20:34Okay, I'm going to close my eyes. Eyes closed. okay here we go totally black currant not grape okay so this is a different purple let's see let's see if i'm pretty sure that this one is the grape one and that one was the black currant yep this one is totally the grape i mean does it taste like grape it tastes like grape flavor whereas the black currant just has a little more richness to it this is just sort of that sweet grapey thing going on, like the Manashevitz grape flavor, Concord grape, whereas the Black Currant has like more depth and complexity even in skittle form. And drumroll, 100 % correct on my first try.

21:16Over to you, Nikki. Okay, I've moved them back and forth, so now you don't know which one is which. And now I'm going to open them up.

21:32it's very sweet okay i'm not gonna say anything until i've tried the other one okay then palm out and dun dun dun dun candy too all right here we go

21:49it's easy the first one is american the second one is blackcurrant congratulations you did it the starburst wasn't a fair comparison because the equivalent in the american package is red it's cherry but in any case nikki and i both aced it we knew which one was supposed to be black current frankly the starburst blackcurrant was not as delicious a representation of black currentness as the skittle, I went back and tried the black current British skittle just to be sure, and then had another American purple skittle just for reference. Mmm. Ugh. The American one is... I feel... I feel sad for the children of America.

22:28It's true. Americans are missing out. Black current is a truly fantastic flavor, even in candy form. But as we said, most Americans have never tried it. I did not grow up eating black currants. I hadn't really heard of them before I got this job. Greg hadn't either. He'd never tried them. But then he found himself in Europe. I was actually in the military. I was in a branch of the military intelligence branch, and I was a Czech and Slovak linguist. And because of what I did with intelligence and so forth, I had a lot of free time. Greg fell in love with all the foods he was eating in Europe, all the fresh produce, all the delicious flavors.

23:02And after a short while having this free time and having this newfound love of food, I decided to do exactly the opposite of what one does. Instead of going to school and learning how to cook and then opening a restaurant, I decided, let me open up a restaurant and I'll learn how to cook. So he did. And behind the restaurant he ran in a little town in Bavaria, Germany, there were some blackcurrant bushes, which is how Greg became acquainted with the blackcurrant. Acquainted and very quickly obsessed. One of the first things that I loved about it was, as I was cooking is I had the ability to really play around with flavor.

23:41In the case of most berries that are sweet, you can't unsweeten a raspberry or a strawberry, you know, and so in the case of currants, I could sweeten them to the point where I could still get sweet notes and tart notes, which wasn't possible in a lot of other fruits. Because black currants are really not all that sweet right off the bush. They're quite tart. And I love that. I just love the flexibility of these little black gorgeous things. Greg came back to America. He left both the military and the culinary world, and he got into horticulture. And after a short period of time, I ended up teaching at the New York Botanical Gardens, which I did for about 25 years.

24:19And during that tenure, I discovered that black currants were illegal in the United States. This is not totally true. They were illegal, but by the 1960s, the white pine industry wasn't as big of a deal. The lumber industry had basically moved on, and the whole ribes quarantine and eradication effort had run out of steam. Because it turns out that all that huge effort to eradicate black currents hadn't actually succeeded in eradicating the disease. Plus, as we said earlier, researchers in Canada had developed varieties of blackcurrant bushes that were resistant to white pine blister rust, and that led to a change in the American law.

24:57Upon the release of those, the United States went, well, I guess this is a little pointless. It didn't super work. There's still white pine blister rust in the landscape, and we haven't been able to get rid of it. And now black currents have the ability to not get it. So I guess we'll get rid of the ban. And then just kind of did it quietly. And so the federal government, as it often does, kicked the restrictions and the law to states jurisdiction. So they said to every state, you decide for yourself whether you want to grow these or not. About a dozen states kept some form of restriction or ban.

25:31The rest quietly took the ban off the books. But New York State, where Greg lives, that was one of the states where blackcurrants were still totally forbidden. In the early 2000s, Greg decided he was ready to start his own farm. He and his wife found property in the Hudson Valley, and he was looking for a specialty crop, one that not everyone was growing and that would make him enough money to keep the farm afloat. As part of his research process, he visited other small-scale farmers in the region who were making a go of it. One of them was a local vintner, and one of his products was cassis, which is black currant liqueur.

26:04And I asked him, because I knew at this point that they were illegal, I said, where do you get your currants? And he said, oh, it's a real pain in the butt. I have to go to Canada and import them, and, you know, I wish that we had them here. And a little light went off, you know. I love it when someone tells me that it's illegal and banned and you can't do it. Greg headed up to Cornell to get some help with figuring out what to do next. He checked in with plant pathologists there. They looked into whether the ban was necessary. And they said, well, there aren't a lot of white pine plantations in the state, and we now have resistant black currants.

26:33So the ban maybe wasn't so important anymore, but the law was still on the books. How do you change a law? I have no idea. I'm not a lawyer. But I went up to Albany, to the state capitol, and I spoke with a couple of people. I spoke with one senator in the beginning, a state senator. and he said, so, you know, how big is the market for black currants? And I said, well, there is no market. It's illegal. You know, there's a couple imported jams, but that's about it. And he said, well, that's not good news. How many farmers? I said, well, it's illegal. There's no farmers. He said, so there's no source of supply and there's no market and I'm going to spend my time changing this law.

27:08It makes no sense. Greg kept going up to Albany each and every week to pester the lawmakers and then the Wall Street Journal heard about him and decided to write an article about his quixotic effort. And it was terrible. It talked about how bad currants tasted. They were tart. Americans were never going to love them. All this stuff. This is 100 % fake news because the black currant tastes delicious. But you know what they say. There's no such thing as bad publicity. And the following morning, I got a call from a state senator way out in western New York who was on the Agricultural Committee. And he said, I read the article.

27:43I'm intrigued. Let's talk. and that was the beginning. And we spent six months crafting a new law. It went up for a vote before the assembly and passed unanimously. The first law that passed unanimously in something like 40 years. The following week it went up before the Senate and passed unanimously and two months later then Governor George Pataki signed it into law and I overturned the ban in New York. Greg became a black currant and also a red currant farmer. He has thousands of plants, he sells some of them to local farms so they can grow black currants too. He also has a whole bunch of currant products, from frozen fruit to juices to jams and chocolate-covered black currants, everything your heart desires.

28:23Lily says for a small-scale grower like Greg, black currants have a lot of potential. Growing blueberries, you're going to be competing against the super-efficient growers of Georgia and Florida and the Pacific Northwest, and you're going to be competing against Chile. And those are really tough margins. But if you're growing a crop that doesn't have a lot of acreage already, That's really appealing to people. Plus, these fruit have been popular for so many decades across the ocean. There's plenty of existing knowledge for American farmers to take advantage of. Black currants have already had the benefit of breeding in Europe and already have a pretty established industry over there.

28:58And they have figured out a lot of these challenges and they've made things like mechanical harvesters. So finding the intersection of crop that's not razor thin margins, but has an industry support network and like tools already developed for it is such a such a boon. For the Savannah Institute, where Lilly works, black currants have another big thing going for them. They grow really well in partial shade, like under solar panels, for example, or alongside trees in what's called an agroforestry system. Agroforestry is the implementation of more trees on farms that can look like diversified orchards or alley cropping or wind breaks.

29:40It can look like any number of systems. And we like agroforestry because it's good for the soil and it's good for the air quality and water quality and it diversifies the income of farmers. That all sounds awesome. Black currents fit into that system perfectly. But the problem is, as we already said, almost nobody here knows about them. There are some Americans growing them in their backyards. There have also been like small farms growing them here and there, mostly people who had also fallen in love with blackcurrants either in Europe or maybe in Canada where they're more common. But there really isn't a market for them.

30:12Americans are not clamoring for blackcurrants. Yet. So for a farmer to grow something without a market, you have to be certifiable, which is what qualified me to do it. And I decided in the beginning that because there was no market, I wanted to make sure that I marketed currants the way that I wanted people to perceive them. So a delicious fruit, a healthy fruit. So black currants have twice the antioxidant of blueberries. They have four times the vitamin C of oranges, more potassium than bananas, calcium, iron, manganese, magnesium, and this little berry that Americans didn't know about. You know, it's really a powerhouse.

30:52Americans do love their health benefits. But Lily is focusing on the flavor aspect. She says most black currants are a little too tart to eat right off the bush, and she's trying to change that for the American palate. By breeding currants that are delicious and great for eating out of hand and are maybe a little bit less pungent, a little bit more sweet, you know, kind of a little bit more blueberry-like, and that work well for our climate and for our growing systems. And we're also trying to increase the marketing of black currants and get people to know more about it. This is the real challenge.

31:27For more than a century, Americans have lived without the black currant. Purple means grape here, but Lily thinks it can be done. She thinks the black currant could stage a comeback. There was no mango flavored products 20 years ago, probably. But people are, you know, it's very common to find now. You can find a mango-flavored Mountain Dew or gummy candy pretty easily. And so I think that trajectory could be similarly adopted for black currants. Just people need to know about them, have the opportunity to try them, be curious, which they already are. You might be wondering, why bother? Sure, black currants are great, but there's lots of great food around.

32:05You can find all sorts of delicious options at the farmer's market and in the grocery store. We don't need no more stinking berries. we've already invented all of them it's fine yeah no if you listen to gastropod you already know why we should bother because making life more delicious is if not the key at least a very big contribution to overall human happiness there's a reason that i work on berries and i don't work on wheat or corn is i love being someone who gets to create joy and like sparkle in the world. And black currants are joy and sparkle. You don't need it to live. It is not a vital nutrient where if you don't eat a black currant specifically, you will die.

32:53But we know that fruits and vegetables are good for us and they have delightful flavors. And it just provides texture to life that makes life full of curiosity and joy and sparkle. I'll raise a glass of cassis to that. Speaking of sparkle, Well, now it's time for the next listener question. This one about a sparkling soda root beer. Why is it called beer? What is it actually supposed to taste like? Is it really made from roots? All that after the break. Is Donald Trump still cool? Well, at first, there's what he was promising to America. He was promising change. Yeah, promising a big change. Has he lived up to that?

33:32No. No, I wouldn't say so. I'm disappointed. We're in Washington, D.C. for one of the events that Donald Trump is throwing for America's 250th anniversary, and it's UFC night. Proud to be American. We got free tickets. It's just going to be a great time. That's about it. It's an opportunity to talk to a group that was central in the 2024 election, young men. Why do we think Trump and men seem to have a connection? I feel like he just knows how to advertise himself as a young and proud. It aligns with masculinity, I feel like, to a certain extent. But if they don't like Donald Trump, what do they prefer politically otherwise?

34:06I care about my family. I care about my country. I want people to be safe and happy where they live. I care about my wallet too, man. I'm Estet Herndon, and this is America Actually. Catch us every Saturday on YouTube or wherever you get your podcasts. As America reaches its 250th anniversary, how should Americans assess their country's strength relative to the rest of the world? We're moving into a genuinely multipolar world, and that's a world in which every nation is basically for itself, because nations can no longer rely on the United States to protect them. I'm John Feiner. And I'm Jake Sullivan.

34:42And we're the hosts of The Long Game, a weekly national security podcast. This week, we sat down with historian and foreign policy expert Bob Kagan to assess America's role in the world at 250 and the future of American power. The episode's out now. Search for and follow The Long Game wherever you get your podcasts. The hero of the story of root beer used to be a household name in America, but not anymore. He was a South Jersey farm boy called Charles Hires, who left home in 1863 at the tender age of 16 to apprentice in a pharmacy in Philadelphia. Hires first struck it big when he discovered something super useful.

35:21There was a basement being excavated in downtown Philly, and he noticed that the earth that had been dug up was a clay called Fuller's earth, which even today is used for cleaning. These days, it's in things like cat litter. Heirs persuaded the builder to let him have the excavated earth for free instead of schlepping it to a dump. And then he packaged it up and sold it as a fabric cleaner, and he made enough money from this free dirt to start his own business. And at that time, druggists were looking for drinks that they could prepare in their shops, and sell over-the-counter. Bill Double wrote a book called Charles E.

35:56Hires and the Drink That Wowed a Nation. Druggists at the time sold all sorts of concoctions, things that were medicinal, and also beverages that claimed to be medicinal. He was just starting out, and he was looking for a drink that he could merchandise. Hires had just got married, and his honeymoon ended up combining business with pleasure. He was staying with his new bride, I think he was 24 and she was 23, at a farm near Morristown, New Jersey. And the hostess prepared him a drink that was described as homemade root beer. He found it very, very interesting. The drink that Hyers enjoyed was something that his hostess had made from foraged teaberry leaves and both the berries and pieces of the root of the sassafras tree, which is a tree that's native to North America and had long been enjoyed in a steeped drink by Native Americans.

36:50You dig up that root and snap it, and you're going to feel like you're smelling a root beer straight out of the ground. Reed Andrew is the founder of the Museum of Root Beer in Wisconsin. These roots of the sassafras tree are kind of like a rhizome-like ginger, and the resulting spicy warm beverage had a reputation as a cural. When Europeans were introduced to the sassafras root, they went wild for it. it was the most lucrative export from the colonies in the early 1600s. The Jamestown colonists legally had to send 30 tons a year to the King of England as part of their charter. Like we said, Native Americans had long been steeping the root like a tea.

37:28But colonists and early Americans, like the woman who hosted Hyers and his wife, they added some sugar and yeast and let it ferment a bit, which made it lightly sparkling. It was part of the world of incredibly low-alcohol drinks that were made with farged leaves and roots and berries and all sorts of flavors. You could get ones flavored with spruce needles or birch bark or just regular hops or a climbing vine called sarsaparilla or, of course, our friend the sassafras root. These sparkling drinks were typically in the range of 1 % alcohol, sometimes a little more, sometimes a little less, which is how they ended up being called small beers.

38:05Normal, non-small beers typically start at at least 4 % alcohol. For small beers, you took all these flavorings, hops, birch, sarsaparilla, whatever, and you could either use the sugar that was provided by leftover grains from brewing beer, or you could use sugar sugar and then just briefly ferment it all together. The whole process created delightful, refreshing, low-alcohol drinks that were often seen as safer to drink than water at the time. In any case, the young, newly married pharmacist Charles Heyers very much enjoyed his first taste of sassafras root small beer. He thought it had real promise, and he cut the recipe for it, and he took it home with him, and he worked on it for almost a year until he found a product that he thought he could put on the market.

38:51Hayers never shared his exact recipe, but Bill says we do know he did include the farmer's wife's tea berry leaves for their wintergreen note and sassafras root and berries, but then he added things like juniper, sarsaparilla, hops, ginger, vanilla, licorice. There were apparently 16 ingredients in all. The result was a drink with a taste that was described as woodsy and minty and a little medicinal. Heyers created a dried powder from all these ingredients, and starting in 1875, he packaged and sold his Heyers root beer extract. And you just had to buy his package of roots and herbs and add sugar and yeast, and it would make five gallons of delicious root beer.

39:32During the whole recipe-tweaking R &D process, Hires always referred to the resulting beverage as root tea, or sometimes herb tea. He was a lifelong teetotaler himself, and he claimed this was a teetotal drink. But Hires had a friend who said Pennsylvania miners would never buy and drink something called root tea. It just wasn't manly enough. There were a lot of miners in Pennsylvania at the time, and Hires was too good a businessman to shut off part of his potential customer base. It would not be as cool if it was called Root Tea. It might not even exist anymore if we went with that name. Coolness or lack thereof aside, Heyer's Root Beer started to really take off, especially when Heyer started selling a liquid concentrate version in 1880, which it turns out you can still find.

40:21I managed to order a very ancient-looking, still-sealed package from that source of all wonder, the internet. We have no idea how old that package actually is. It's unlikely that it's part of his original batch from the 1880s. We do know that in general, this liquid extract was made and sold all the way through the 1980s. But that bottle looked older than something from my childhood, to be honest. It was old. No idea how old. The liquid concentrate had sort of turned to cement in the bottle, so it took an absurdly long time to get it out. And then I popped it in the blender to re-liquidize it.

40:56It was a project. Now I have sort of grainy black sludge. It really does look like some kind of petrochemical waste product. Smells very intensely of root beer. Nikki spooned half into a tiny little glass jar and shipped it all the way across the country to me in Somerville so we could both have the delight of attempting to recreate this original Hire's root beer from scratch. I know this is ancient, and I don't know if it's toxic at this point, but it really smells like root beer. It's kind of shocking. I did read the ancient instructions that came with the ancient package. It says, do not use more yeast than specified, otherwise the drink will be unpalatable.

41:42I sense it may be unpalatable whatever I do, but we've got to give it our best shot. But it turns out that not for the first time in my life, I did not read the instructions closely enough, and I added the yeast directly to the sugar sludge mix, which was wrong. Oh damn, I was supposed to bloom that in water instead. I also read the instructions, and like Nikki, I attempted to follow them. The instructions said to bloom the yeast, specifically in lukewarm water, so I asked my spouse Tim, who's a baker, and he said to warm the water a little. I did that, and then I bloomed the yeast. Add to the sugar, mix well, bottle immediately.

42:20It should be someplace relatively warm, well that's the house right now, two to three days after being bottled. Maybe keep them in the tub in the guest bathroom in case anything explodes. Alright, here we are. Successfully bottled and now I'm putting the caps on. Good luck, brown liquid. I wish you well. We set our freshly made Hires root beer aside to ferment for a couple of days and return to the late 1800s. Heyers very smartly moved on from this method, and in 1884 began selling a sweetened syrup version of his extract for use in brand new soda fountains, which were the cool new thing. And he was two years ahead of what became the most famous drink from that time, Coke.

43:05In fact, Heyers Root Beer was one of the very first commercial soda fountain soft drinks. And unlike his rivals, Coca-Cola, Pepsi-Cola, Moxie Nerve Tonic, Heyers never put anything in his root beer to give it more pep, other than sugar, of course. Root beer never had caffeine or cocaine or any of the other pep-producing popular ingredients of the day. What his root beer did have was one of the earliest advertising budgets. He was riding on a streetcar one day to work, and a gentleman who knew of his root beer came down and sat down beside him. It turned out to be the editor of the Philadelphia Ledger, and he said, that root beer is good, why don't you advertise it?

43:50Myers said he couldn't afford to pay for advertising, and the editor said, well, how about we run your ads and I won't send you a bill until you ask for it? Myers was willing to take a chance on that, and when he got the first bill, it was$700. He nearly fell off his seat. But he looked at his sales and he saw it was working. He stuck with it, and he advertised it, and he kept advertising it, And he exaggerated it very, very strongly as the world's greatest health-giving beverage. Famously, most Heyers root beer ads starred what came to be known as the Ugly Baby, an illustration of a random blonde German toddler-age kid who only his mother, and apparently Charles Heyers, could love.

44:35The face of this child was on everything. There's one face of a baby who's crying because the root beer was taken away. A crying, ugly toddler baby doesn't seem like it would attract new customers. But Heyers Root Beer got huge, and as it did, Heyers reinvested money in advertising, which was a virtuous circle of success because that advertising kept on working. By 1910, Heyers Root Beer was one of the most popular drinks in the country. It was up there with Coke. I would say that Root Beer rivaled every soft drink for the first 20 or 30 years. Despite that early success, Heyer's Root Beer never took over the world.

45:15Colas like Pepsi and Coke, and then the lemon-lime sodas like Sprite and 7-Up, they were the real juggernauts. Root Beer may not have been as popular, but it did stick around over the decades as a soft drink option. The Heyer's brand, though, it was sold a couple of times. And in the end, Dr. Pepper Keurig Corporation purchased Heyer's Root Beer, and they phased it out. Reed remembers his last sip of the original Hire's Root Beer with fondness. I pressed the Hire's button on a little soda machine next to a gas station in a small Wisconsin town. I thought, yeah, that's Hire's. And I had no idea it would be my last drink of Hire's.

46:00As of now, it's going to be the last one, unless somebody can get another batch made. Fear not, though, hires may be gone, but root beer hasn't disappeared. At least not in America, which is really the only place that root beer ever was and is popular. Root beer's not number one, but it's a mainstay. It is consistently a part of American life. But growing up in England, I never encountered it. And I've literally had a woman from the UK in the museum make a disgusted face when tasting root beer. And her and her husband said, ew, it's like we're at the dentist. In America, where we don't think it tastes like you're at the dentist, A &W is the most popular root beer today, but there are lots of root beers.

46:50Most of them are made with artificial flavors, just like all soft drinks. But there are also craft root beers that are actually brewed with roots and herbs and things. I realized while I was making my own Hire's Root Beer homebrew that I had never actually tried a root beer. My only experience of the flavor was root beer flavored jelly bellies. So I decided to fix that by going to my local soda pop emporium, which stocks about 50 different kinds of root beer. I may have got a little carried away. Yeah, one, two, three, four, five, six, seven, eight, nine, ten. And if you include this asperola that I already had in my fridge, yeah.

47:29Wow, I have four. I did go a little nuts. But it's my first time. We decided to start our root beer tasting session with the homebrew because, well, I was a little terrified that we were going to poison ourselves and I wanted to get it out of the way. I just hope it doesn't kill us. I mean, I don't... You know I'm an optimist, but I fail to see how it could actually kill us. That said, it did look really pretty dubious. But listen, we will do almost anything to bring you this show. We didn't know how carbonated it would have gotten after a couple of days of fermenting, so we carefully opened the tops.

48:01Ew! It smells really revolting. Holy moly, is all I have to say about that. I don't think I've smelled anything so bad. It was like putting my nose in a sewer. Holy, holy. It is gross. Wow, Cynthia, are we really going to drink this? That smells so bad it's intense. But we did. We each poured a delicate serving out over some ice, took a deep breath, and tried it. Cheers, Cynthia, it's been real. Okay, I'm going to take a tiny sip.

48:28I just spit it back in the glass. Oh, mine tastes like way better than it smells. It's quite, I mean, it's got that medicinal root beer wintergreen thing, but it's perfectly palatable. I'm going back for a second sip. Ugh, definitely not. Tastes about as bad as it smells. It's a really light carbonation. It's not too sweet. It's quite delightful, actually. Huh. Maybe when I messed up the instructions, I ended up with something new and I would drink this. I'm guessing that I used too much yeast because half of the printed recipe meant using one-sixth of a teaspoon, and that was really hard to measure.

49:07And if you'll remember, too much yeast makes the resulting drink unpalatable. Or, I mean, totally disgusting. We thought it was only fair and reasonable to try the most popular root beer next, A &W.

49:22smells totally like root beer just what i expected to smell like there is a whole lot more bubble going on that tastes like root beer i don't really know how to explain it other than it tastes like root beer it has that rooty earthy bit it's very sweet this a and w i would never drink it's it's like syrup it is and the winter green note is really a little much then we tasted the ones that were actually made with real roots and other botanicals. We each had a different brand, but we both thought they were an improvement. Oh, nice. Balanced. This one is like, I'm lovely with a bunch of things going on.

50:00This one for me is the closest to my hires in that it's just feels like a refreshing, slightly spicy herbal tincture. Yeah. It's still a little too sweet, but... This to me isn't spicy. It's spiced, but it definitely is like that. That's what I mean, and like warm. That was peak root beer. And then I kept going and things went downhill from there. One root beer tasted too much like vanilla. One was too gingery. All were way too sweet and none were anything I'd ever voluntarily drink again. I know they all have their fans and I'm sorry. But our listener Rachel wanted to know the difference between root beer and sarsaparilla soda.

50:40The original Hire's recipe did have sarsaparilla in it, but we each got a bottle of sarsaparilla to see what it was like straight. It tastes a lot like root beer. It feels like a little more, mine is a little more musky and a little more tannic. But really, in a blind taste test, I'd be hard pressed. Which is not surprising because sarsaparilla and sassafras taste remarkably similar and in fact were often used together or interchangeably throughout the history of these root beverages. Honestly, the world of small beer was kind of a free-for-all, and we're just living with the chaotic flavor consequences.

51:16If you're curious about what sassafras and sarsaparilla have to do with both MDMA or ecstasy and the Smurfs, you'll want to get a hold of our upcoming newsletter for our special supporters at gastropod.com support. Huge thanks to listeners Rachel and Russell for such fascinating questions, and to our experts Lily Hislop, Greg Quinn, Bill Double, and Reed Andrew for helping us answer them. We have links, etc. at gastropod.com so you can learn more and, of course, get a hold of some black currant-y goodness yourself. Thanks, as always, to our fabulous producer, Claudia Geib. We'll be back in a couple of weeks.

51:51Till then.

Fan favorite Ask Gastropod is back, and we’re celebrating the season by solving a pair of trans-Atlantic mysteries! First up: if you have a purple candy in Europe, it’s nearly guaranteed to be flavored with a tart little berry called blackcurrant—while the same color candy in the US is almost always grape. One intrepid Gastropod listener wanted to know: why the difference? We’ve got the story of how a tree so important it was on early Americans coins inspired the botanical witch hunt that made a delicious fruit illegal this side of the pond—and how to try the fabulous flavor we're missing out on! Plus, lager and ale lovers around the world would be deeply confused by the warmly spiced soda that Americans call “root beer.” So where did this non-alcoholic beverage come from, what are these mysterious roots, and why is it called beer? It’s a tale of tea, teetotalers, and a ubiquitous ugly baby—and because we at Gastropod will put our stomachs on the line to get to the truth, we attempted to brew the original recipe to taste it for ourselves.
