Microbe new to science found in self-fermented beer: New technique helps disentangle the various species of yeast and bacteria

Microbe new to science found in self-fermented beer: New technique helps disentangle the various species of yeast and bacteria that live in “'wild beer”'

"In May 2014, a group of scientists took a field trip to a small brewery in an old warehouse in Seattle, Washington. They were looking for some yeast to sequence—and to taste some beer, if it came down to it. Cody Morris, then brewmaster of Epic Ales, ushered them through the building, warning of a large hole in the floor. Then he brought the group over to one of the old wine casks in which Morris was brewing a “wild beer.”

The scientists dubbed the new hybrid Pichia apotheca - Greek for “warehouse.”"

Most brewers try their best to avoid wild strains entering their beer. It seems some wild yeast may be useful for flavour and stability but maybe not predictability (until it's available as a dried pure culture).
