Locally Sourced Yeast from the Chicago Area
WARF: P150032US01

Inventors: Chris Hittinger, Ryan Moriarty

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing wild strains of yeast that potentially could be used in craft fermentation.
Overview
Saccharomyces cerevisiae, Torulaspora delbrueckii and Hanseniaspora uvarum yeast strains have long been associated with industrial and natural fermentation processes, including beer and wine production. There is growing interest among brewers for ‘locally sourced’ ingredients, including yeast.
The Invention
UW–Madison researchers and others recently identified novel strains of Saccharomyces cerevisiae, Torulaspora delbrueckii and Hanseniaspora uvarum. The strains were isolated in the Chicago region from soil, bark and fruit samples submitted through the citizen science branch of the Wild YEAST Program. The multiple strains may be of interest to the craft brewing industry.
Applications
  • Novel yeast strains for beer and wine fermentation
Key Benefits
  • Unknown flavor and aroma characteristics
  • Special significance to Chicago area brewers
Stage of Development
The strains were identified based on DNA barcode sequencing in August 2014.
