Long before European settlers set foot on North American soil, the continent’s indigenous peoples were brewing a beer that bubbled with the spirit of the land itself—corn beer. Maize, a staple crop domesticated in the Americas thousands of years ago, wasn’t just food; it was a sacred gift, a source of sustenance, and, in the hands of skilled brewers, a pathway to celebration and ritual. From the Andes to the American Southwest, corn beer wove itself into the cultural fabric, and its legacy endures in North America’s brewing history.
In the pre-Columbian era, corn beer was a cornerstone of indigenous life. In the Andes, the Wari culture (600–1000 AD) relied on elite women to brew chicha, a fermented maize beverage, for feasts and ceremonies. Archaeological digs at Cerro Baúl in Peru reveal sprawling breweries where sprouted corn kernels were malted, not chewed, as some myths suggest, to convert starches into fermentable sugars. These brews, sometimes flavored with Peruvian pink peppercorns, were potent enough to fuel social bonds and religious rites. Farther north, in what is now Mexico, the Tarahumara people crafted tesguino, a sacred corn beer brewed for Holy Week celebrations, using sprouted maize and wild herbs. The Apache and Chiricahua, in the American Southwest, fermented tiswin, a “yellow water” made from ground, sprouted corn flavored with locoweed or lignum vitae roots, often after days of fasting to amplify its intoxicating kick.
When Europeans arrived, they brought barley-based brewing traditions, but corn was already king in the New World. The Pilgrims, landing at Plymouth Rock in 1620, ran low on beer and learned from Native Americans to ferment maize with birch sap and water. By 1622, John Winthrop Jr. presented a paper to the Royal Society on malting maize, signaling early colonial interest in corn as a brewing grain. In Virginia, settlers like John Smith reported brewhouses producing beer from native corn by 1629, a practical choice when barley was scarce and imports costly. These early beers, often flavored with molasses, sassafras, or spruce, were rough but vital, sipped from waxed leather tankards called “black jacks.”
Corn’s role grew in the 19th century as German immigrants reshaped American brewing. Their beloved Bavarian lagers, made with two-row barley, didn’t translate well to America’s protein-heavy six-row barley, which produced hazy, unstable beers prone to spoilage. Enter corn, abundant and cheap, with a low-protein profile that lightened body and color. By the 1870s, brewers like John Glatz in Oshkosh, Wisconsin, and the Pabst Brewing Company were adding corn grits—about 20% of the grain bill—to their mashes, guided by brewing scientist Anton Schwarz’s influential articles in The American Brewer. The result was the quintessential American lager: pale, clear, and crisp, perfect for hot summers and rapid drinking. In 1878, Anheuser-Busch’s corn-infused lager won a grand prize in France, outshining European rivals despite Germany’s strict Reinheitsgebot purity laws.
Corn wasn’t just a fix for barley’s flaws; it was a cultural fit. North America’s vast cornfields made it a natural choice, unlike barley, which farmers loathed for its spiny awns and low market value. Brewers experimented with forms—grits, flaked corn, even cornmeal—to achieve a smooth, dry finish with a neutral sweetness. Beers like Krueger’s Finest, canned in 1935, and mass-market lagers from Budweiser and Coors leaned on corn for their light, approachable profiles, often using up to 30% corn to keep flavors clean and calories low.
But corn’s reputation took a hit. By the mid-20th century, craft beer purists scorned it as a cheap filler, blaming corn syrup (like NU-BRU, used by Oshkosh Brewing in the 1960s) for bland, mass-produced lagers. A 2019 Bud Light Super Bowl ad mocking rivals’ corn syrup use didn’t help. Yet, the tide is turning. Craft brewers like Fonta Flora and Black Narrows in Virginia are reviving corn’s legacy with heirloom varieties like Bloody Butcher and Hopi Blue, grown by Native farmers. Trillium’s Crib lager, brewed with Valley Malt’s malted corn, and Cruz Blanca’s Mexican-style lager, with 70% Bloody Butcher, showcase corn’s spicy, peppery depth. These beers, often gluten-free like Dos Luces’ chicha-inspired brews, honor indigenous traditions while pushing flavor boundaries.
Corn beer’s journey in North America is a story of adaptation and resilience. From sacred tiswin to colonial experiments, from 19th-century lagers to modern craft revivals, maize has been more than an ingredient—it’s a thread connecting cultures across centuries. So, on National Beer Lover’s Day, crack open a corn lager and toast to the grain that’s been brewing history since the dawn of the Americas.
