Magical microbe: A wild yeast sourced from Wisconsin is ushering in a whole new class of beers

Noted: UW-Madison genetics professor Chris Hittinger co-authored the study describing the breakthrough. He continued his wild yeast research in Wisconsin, and a few years later, he and a team of students found Saccharomyces eubayanus in a park near Sheboygan, Wisconsin. It was the first — and so far the only — time the species had been identified in North America. “Because Saccharomyces eubayanus has been so rarely isolated from the wild, this is really a unique opportunity for study,” Hittinger says. “It seems to be very rare.”
