My first glass of black, undiluted, pure robusta was a punch within the neck. It was 2,000-proof vodka plus caffeine. It made me need to dive, open-mouthed, right into a swimming pool full of candy cream. This was nothing like the opposite wimpy factor referred to as “coffee” I’d spent my total life consuming, and at some primitive, sensory degree, I struggled to course of it. But I managed my expression as a result of Bang Duong, the person who’d grown and roasted and brewed this Thorlike drink, was seated proper throughout from me. It was January 2020, and we had been on the second flooring of Ho Chi Minh City’s Tractor Coffee, a mecca of reclaimed wooden, unfinished metal, and burlap tones that wouldn’t be misplaced in Berkeley or Berlin save for one factor: Tractor was one of many solely cafés I may discover that made seed-to-cup espresso from the world’s least liked number of bean. That may make it the staging floor for a far-fetched culinary revolution.
In the world of elite espresso, promoters of robusta beans—lengthy referred to as an inexpensive, low-grade filler crop that goes into instantaneous grounds—are considered with both condescension or mistrust, as if they’re peddling promenade corsages created from freeway weeds. Indeed, eight years earlier, Duong had been simply one other farmer in Bao Loc rising the tough stuff—low-grade robusta utilized in avenue espresso. But in contrast to many cash-croppers, he was much less thinking about short-term positive factors. He revered robusta and didn’t imagine that there was something inherently dangerous about its style. It’s completely different. It’s particular, he informed himself. And then he set himself a purpose to “prove robusta can be good.”
“Most robusta in Vietnam is harvested quite green,” Duong informed me via a translator. “But coffee made from unripe beans doesn’t taste good.” Crops ripen in waves, he defined, however as the price of labor has skyrocketed together with the remainder of the Vietnamese economic system, many robusta farmers can afford to reap simply as soon as. Harvesting early additionally helps farmers keep away from the not-uncommon drawback of thieves sweeping their orchards clear of espresso cherries.
Duong determined to select “only the reds”—the ripest cherries. He constructed a greenhouse, in order to raised management his drying and processing. And he swore off roasting his robusta with rice wine or fish oil or any of the unique flavorings that avenue sellers use for micro-branding and to chop their drinks’ astringency. Soon he started to note a discernible enchancment in style. Duong was following within the footsteps of one other maverick farmer from Bao Loc, Toi Nguyen, who had managed to obtain specialty-grade requirements for his robusta crop. Just a couple of months earlier than I visited the nation, he’d had his beans and brew appraised by skilled consultants at a global espresso convention and acquired a “cupping score” of 85 (out of 100). It was a brand new all-time excessive for robusta.
“A lot of people in the specialty world think robusta is garbage juice,” Will Frith, a specialty-coffee entrepreneur in Ho Chi Minh City, informed me. Tasters for the web site Coffee Review have in contrast its scent and taste to that of “boiling water poured over an old board,” “salted meat,” or “rotten compost … with a hint of sulfur.” But Frith identified that the bean’s notoriety—and the truth that speciality importers had been loath to purchase it—meant that growers had had little incentive to enhance its high quality. “All of the research dollars have gone into arabica,” he mentioned, referring to the different well-known species of bean—the one that’s now synonymous with premium espresso.
Frith, who grew up within the U.S. with a Vietnamese mom, spent years within the highest echelons of the espresso priesthood, working as a roaster within the Pacific Northwest. Since 2018 he’s been in Vietnam, as a free-floating, animating pressure for that nation’s home specialty-coffee trade. “When I tasted fine robusta, I saw potential,” he informed me. “I got excited. The best arabicas remind me of a negroni or vermouth or something on that end, and the best robustas of the smoky scotches.” If the remainder of the world is sluggish to catch on, that has extra to do with espresso’s previous than its current. “It’s like, where do you put this thing that’s always been automatically perceived as low-quality when you’re trying to create the high-quality version?” he requested.
In different phrases: How would you go about promoting the perfect worst espresso on the earth?
A robusta revolution, if it comes, could be a culinary Hail Mary: a technique to mitigate the creeping harms of world warming and save the expertise of “good coffee” as we all know it. But the obstacles it faces, culturally and logistically, are immense.
The two best-known species of espresso beans—Coffea arabica and Coffea canephora (robusta)—have developed, over the previous 30 years or so, a Manichaean status. Kenneth Davids, the editor in chief and “lead cupper” for Coffee Review, summed up the idea system of these he referred to as the “specialty-coffee people” at a espresso convention in El Salvador in October 2013: “Arabicas are godly and right; Robustas are satanic and evil.” Indeed, the specialty-coffee growth of the Nineteen Nineties—the demand shock that carried Starbucks to world dominance—got here in response, and revulsion, to instantaneous espresso created from robusta, which had been ubiquitous up till that time. Consumers got here to really feel that they deserved a better-tasting, much less bludgeoning cup.
Davids hinted in his convention presentation that this backlash was itself a bit too robust. Robusta has its personal intriguing properties, he mentioned—a universe of tasting notes that had barely been explored. “We will never find out what fine robusta’s potential is,” Davids pleaded, “if we keep it shut up in a conceptual box constructed out of judgments concocted by well-meaning people 40 years ago.” But there was one other, way more urgent motive to advertise robusta development, he informed his viewers: the local weather.
Even tiny modifications in rainfall or air temperature have a dramatic impact on the yield and bean high quality of arabica. According to a examine printed earlier this 12 months in PLOS One, local weather change may shrink the areas best suited for arabica cultivation by greater than half throughout the subsequent three many years. (Rising temperatures will open new areas to arabica growers too—however, in accordance with the examine, the commerce is nowhere close to even.) Many consultants imagine that by 2050, specialty espresso as we all know it may very well be prohibitively costly. And even should you are prepared to pay $15 on your Kenya Kirinyaga Kamwangi chilly brew, there’s motive to anticipate that it received’t style pretty much as good because it did earlier than.
Davids, together with many different espresso consultants, now believes that robusta may very well be a part of the answer. It’s a considerably hardier plant than arabica: It grows at decrease elevations, and its espresso cherry’s extra-high caffeine content material could improve the tree’s pure safety in opposition to bugs. It can also be extra resistant than arabica to modifications in temperature and yields extra beans per acre. In mild of all of those benefits, and given the present price of world warming, a mainstream embrace of robusta may purchase us a pair extra many years of inexpensive macchiatos.
That embrace would possibly nicely start in Vietnam: the world’s largest espresso producer after Brazil and, extra vital, the world’s prime supply of robusta. For many years, these beans have been reviled, but robusta has remained deeply ingrained within the native coffee-drinking tradition, the place persons are aware of its smoky bitterness, its flaws and components, its double dose of caffeine. The Vietnamese custom of including sweetened condensed milk serves partly to masks robusta’s astringency.
If anybody is aware of how greatest to reinvent robusta, it might be the espresso farmers, roasters, and brewers who’ve supplied the world with the majority of it for many years, and whose home prospects have by no means stopped having fun with it.
Vietnam has turn into, lately, a hotbed of espresso innovation. When I arrived there, reporting for a shiny journey journal simply earlier than the beginning of the pandemic, I discovered a vibrant, artisanal espresso scene: Appointment-only speakeasies served cherry-to-cup Vietnamese arabica; garnering an invite required following the proper Instagram account or catching phrase of mouth within the basement of an aspiring nano-roaster. At experimental espresso labs, auteur roasters washed their beans with contemporary pineapple juice and different native substances to create tropical riffs on a centuries-old drink. And—most notable—at storefronts like Bang Duong’s in Ho Chi Minh City, a brand new era of brewers had been doing every part they might to flip the legacy of robusta espresso.
Newfangled robusta-based espresso manufacturers have popped up elsewhere on the earth, however these are pitched much less to connoisseurs than to masochists and tweakers—they’ve names like Black Insomnia and Death Wish, they usually provide a one-cup dose of caffeine that exceeds the FDA-suggested most day by day allowance of 400 milligrams. A mug of Brooklyn-based Biohazard espresso offers you a lift equal to about 4 cups of the standard stuff. But the Vietnamese robusta revival—with its concentrate on taste over horsepower—has additionally made some inroads within the U.S. market. This previous summer season, a one hundred pc Vietnamese robusta espresso referred to as Truegrit, made by Nguyen Coffee Supply, hit the cabinets of Whole Foods in New York City.
Truegrit is the brainchild of Sahra Nguyen, a first-generation Vietnamese American whose personal quest to make robusta a factor had appeared far-fetched once I first met her again in 2019. At the time, Nguyen Coffee Supply was little greater than a 12 months outdated, and its solely retail outlet was a four-month pop-up at Cafe Phin, a Vietnamese restaurant on New York City’s Lower East Side. Fast-forward three years and Nguyen Coffee is being bought or served in additional than 60 shops all through New York and 11 different states, in addition to at a mini-mart in downtown Toronto. Nguyen informed me that she’s spent the pandemic years making an attempt to interrupt down the specialty-coffee trade’s resistance to robusta, usually with dispiriting outcomes. (“Sadly, we don’t feel the world is ready for Robusta beans just yet,” learn one typical rejection.) But she continued to extol enhancements in bean-growing-and-processing strategies, and to “frame it as this larger conversation about economic justice and sustainability for growing communities as it relates to what we like to drink.” It helps that Nguyen’s robusta is available in a superbly designed bundle with glossy, sans-serif fonts: the unSanka.
Chris Manca, the Whole Foods purchaser who made the choice to hold Nguyen’s espresso, informed me that he’d been glad to have the possibility “to educate people about robusta coffee and to give customers the opportunity to try something they had maybe never fully understood.” But given how specialty espresso has historically been marketed—i.e., If it’s not arabica, it’s crap!—Manca should do a good quantity of reeducation too. Back in 2013, throughout his robusta-semiotics speak, Kenneth Davids had identified that “No Robusta” was a standard boast amongst specialty-coffee producers, and a sign to customers that the impurities of their espresso had been fastidiously culled. When we spoke final month, he was cautious of coming off as Pollyannaish in regards to the bean. Yes, with concern about local weather change and sustainability at an all-time excessive, an organization like Nguyen Coffee Supply may nicely discover new adopters for robusta. But its taste limitations are very actual, he mentioned, pointing me to a passage from his current e book, twenty first Century Coffee: A Guide, the place he wrote that robusta won’t ever have as engaging a style, total, as arabica. “The famous Kaapi Royale grade of wet-processed Robusta from India, for example, displays an impeccable 0% physical bean imperfections,” it mentioned. “Yet even such squeaky clean Robustas are too bitter, with too much grainy nut and not enough chocolate and fruit to make an attractive single-origin beverage.”
Others within the specialty-coffee trade had been extra blunt. The case for robusta, Arno Holschuh, the chief espresso officer at Bellwether Coffee in Berkeley, informed me, is “kind of like the Soylent Green argument: It’s like, the future is going to be so awful that you’re going to have to learn to love robusta.” I considered Will Frith’s declare that the perfect robustas may very well be “the smoky scotches” of the espresso world—just a little harsh at first, maybe, however delivering a rewarding complexity and depth. That’s not how one hundred pc robusta struck me two years in the past once I had a cup in Vietnam. It wasn’t smoky; it was ash. Much as I attempted, I discovered it undrinkable.
This October, I paid a go to to Nguyen Coffee Supply’s sales space on the New York Coffee Festival. It was the one one representing robusta espresso on the expo, however the firm made up for it with sheer exuberance; there was a Roll With Robusta Skee-Ball sport, a robusta augmented-reality expertise that conjured a can of the corporate’s new ready-to-drink robusta chilly brew, and Powered by Robusta T-shirts on the market. Walking among the many pageant cubicles, it was laborious to not discover how esoteric our need for ever newer, higher, or weirder types of espresso had turn into: I noticed culinary “coffee paste” created from overwhelmed honey and espresso machines that promised “precision dosing to a tenth of a gram.” Coffee is an acquired style, whether or not it’s created from the most cost effective robusta pebbles or the best Ethiopian arabica. We spat it out as youngsters, labored laborious to love it as youngsters, and now spend our grownup lives fetishizing its bouquets. The majority of arabica tastes horrible, too, Kenneth Davids identified to me, except it’s coddled, massaged, and blasted with an embarrassing degree of human ingenuity. What would occur if we had been to use this identical degree of obsession to robusta?
Here within the U.S., we’ll quickly have extra alternatives to seek out out. Already, in Vietnam, the marketplace for high quality robusta has exploded. After the pandemic hit, Frith pivoted his roasting enterprise to maintain from going bankrupt: He launched his personal espresso model, Building Coffee, and as we speak “fine robusta” accounts for 40 p.c of manufacturing. Inspired by pioneer robusta farmer-roasters like Toi Nguyen (whose cupping scores now land within the 90s, on par with the fanciest arabica coffees), a whole lot of quality-robusta producers have sprung up in Vietnam. In Ho Chi Minh City, two new cafés are targeted completely on tremendous robusta, with arabica relegated to token standing, like decaf; and Tractor Coffee is serving tremendous robusta in each variation—espresso, Vietnamese type, no matter—alongside its arabica choices.
When I spoke with Duong final week, once more by way of translator, he admitted that the robusta he’d served me again in 2020 wasn’t excellent. It turned out that the soil through which he’d been rising his robusta timber was nonetheless laden with chemical pesticides from the Instant Era, which he mentioned had permeated the processed espresso cherries, inflicting “undesirable taste traits.” Duong had spent the previous two years ready for the pesticides to clear earlier than introducing natural fertilizer. This is now widespread observe amongst robusta growers, he informed me, leading to “a much cleaner cup and more clarity in the desirable flavor notes.”
Meanwhile, given Americans’ lust for espresso innovation—and appreciation for a comeback—robusta’s rise could proceed right here as nicely. Perhaps someday quickly, espresso sourced from Vietnam might be branded with its personal gourmand bona fides: No Arabica!
