Excerpts from the article:
"Dogfish Head’s Theobroma beer...one of the Delaware brewery’s “liquid time capsules”: it was created in collaboration with biomolecular archaeologist Patrick McGovern who, according to his University of Pennsylvania webpage, is “known as the ‘Indiana Jones of Ancient Ales, Wines, and Extreme Beverages.’”
..."trace residues of an unidentified beverage on ancient Mesoamerican pottery fragments"...
"The jars and bowls in question dated back to 1400 B.C....excavated from Puerto Escondido in modern-day Honduras, in an area called the UlĂșa Valley, known (according to records from the sixteenth century, when the Spanish invaded) for its excellent cacao. Henderson’s theory was that the people of Puerto Escondido had been among the earliest to domesticate Theobroma cacao, and that the pottery fragments he had found might once have contained a “frothy chocolate beverage.”
"...in a section of his book titled “Theobroma for the Masses,” McGovern describes his collaboration with Dogfish Head craft brewers Sam Calagione and Bryan Selders to create a beer based on the core ingredients of early New World alcohol: chocolate beans (in nib form, as the cacao pods are too perishable to transport from Honduras to Delaware), honey, corn, ancho chillis, and annatto.
McGovern adds: "We might also have tossed in peppery “ear flower” or a hallucinogenic mushroom if they had been available. The fermentation was carried out with a German ale yeast, which is not obtrusive and brings out the flavours of the other ingredients".
"The result? Cloudy and quite strong (9% A.B.V.), but more refreshing than you would think: the chocolate is savoury rather than sweet, and the chilli is just a very subtle, almost herbal, aftertaste. There is almost no head"...
