Then there are what might be the best-known historic beers: the widely available Ancient Ales from Dogfish Head Craft Brewery, including the Midas Touch, based on ingredients found in the 2,700-year-old tomb believed to have belonged to King Midas; and Theobroma, inspired by chemical analysis of a Central American fermented chocolate drink from 1200 B.C. Dogfish Head released its next installment, the ancient-Egyptian-style Ta Henket, on Monday— the latest example of one of the beer world's most enduring and romantic trends.
"There's really a growing interest in re-creations — huge interest, I think," says Patrick McGovern, a biomolecular archaeologist at the University of Pennsylvania Museum who has conducted the scientific and historical research behind the Ancient Ales. Although he has an exclusivity agreement with Dogfish Head, he estimates that the number of brewers asking him to collaborate on re-creations has doubled or tripled within the past six months. He says he has even been approached by beer-industry giants, including MillerCoors.
Of course, re-creations of historic beers are as old as the craft beer movement itself. Many of America's best-loved styles, such as saisons, hefeweizens and imperial stouts, were once on the brink of disappearing, and many were saved by breweries that championed them. During the 1970s and '80s, for example, San Francisco's Anchor Brewing revived interest in not only California steam beers but also chocolate- and coffee-flavored porters, which brewers had largely cast aside.
Nowadays, ever-more-obscure styles are reappearing with increasing frequency, from Polish smoked-wheat beers to the English strong ales known as Burtons. Among the more prominent examples: the ancient Scottish beers resurrected by the Scotland-based Williams Brothers Brewing; the Ales of the Revolution series from Philadelphia's Yards Brewing, including Thomas Jefferson's Tavern Ale and Poor Richard's Tavern Spruce Ale; and the early British recipes dredged up by beer blogger Ron Pattinson, who has collaborated with the Boston area's Pretty Things Beer and Ale Project and Brouwerij de Molen of the Netherlands.
