Is Beer Made With Roast Chicken Tasty?
Independent brewers are playing with ancient ingredients to invent new flavors.
Pull up a bar stool and prepare to open both your mind and your palate: It's time to meet beer before it settled down into the fizzy brown brew we know and love today. The ales in this episode of Gastropod represent the future of flavor, but take their inspiration from the pre-industrial pint. Join us as we meet brewers who are making beer with local herbs, roast chicken, and yeasts scraped off the skin of wild blueberries—and then taste the surprisingly delicious results.
Humans have been drinking beer for at least nine thousand years—and, for almost all that time, beer looked nothing like the industrial lager or hop-heavy craft brews popular today. All across the ancient world, from Egypt to China to South America, our ancestors figured out how to ferment wet grains, and then flavored the buzz-inducing result with whatever they thought might make it more palatable. Though today brewers consider hops a crucial ingredient in beer, it wasn't until medieval Europe that the bitter plant became a popular addition; until then, hops were just "one of the bazillion things you could put in a beer," brewer Butch Heilshorn told Gastropod.
But, five hundred years ago, two Bavarian Dukes passed the Reinheitsgebot: a purity law that stipulated that beer must only contain barley, water, and hops. And while many contemporary craft brewers certainly do include additional ingredients that would violate this purity law, hops have become a foundational ingredient in nearly all beers around the world. Earth Eagle Brewings, the Portsmouth, New Hampshire-based brewery Heilshorn co-founded in 2012, is the exception to the rule. Heilshorn brews a new hop-free "gruit" every week. Just like generations of pre-Reinheitsgebot brewers, Heilshorn relies on a gruit, or blend of herbs, to bitter, preserve, and flavor his brews—the same functions performed by hops, but without the plant's soporific effects. Made with local weeds such as sweet gale and yarrow, the resulting ales taste herbal, earthy, even medicinal—and completely unlike anything most modern drinkers would recognize as beer.
Yeast is another crucial ingredient in beer that's become standardized and industrialized. Before the 1860s, when Louis Pasteur proved that yeast causes fermentation, brewers unwittingly relied on wild local yeasts floating in the air, or cultured their own house yeast through intuition rather than science, re-using barrels or saving the dregs of one batch to inoculate the next, giving each local brew a distinctive taste and aroma. Post-Pasteur, yeast became stabilized, purified, and optimized. Today, most brewers simply order one of a few dozen yeast strains—“German Ale,” say, or “Czech Pils”—from a catalogue. In the second half of this episode, we visit Bryan Greenhagen of Mystic Brewery, who is among a handful of brewers exploring the pre-industrial flavors created by wild and local yeasts. In 2013, Vinland 2, which Greenhagen made using yeast cultured from a Maine wild blueberry, became the first beer fermented solely with indigenous yeast to win a prestigious Gold Medal at the Great American Beer Festival.
In this episode, we taste contemporary beers made with wild yeasts and herb blends—beers that, in many ways, more closely resemble those our ancestors drank for millennia, before purity laws and scientific advances. But Heilshorn and Greenhagen are not obsessively hewing to historical recipes in an attempt to reconstruct the past; instead, they're part of a new wave of independent brewers who are trying to expand the flavor profile of beer by drawing inspiration from its more creative, less rigid roots. And that's something to which even the most hop-mad, IPA-obsessed craft beer fan can raise a glass.
