Distinctive domestication of farmhouse beer yeasts preserved pre-industrial genetic and phenotypic diversity.

Abstract excerpt

Since its inception over 10,000 years ago, beer brewing has transformed from a domestic activity based on uncontrolled spontaneous fermentations into a highly optimized industrial process that uses pure single-strain starter cultures of Saccharomyces yeasts. Along with the storage of frozen yeast stocks, this shift halted the domestication process of beer yeasts and led to a massive loss of beer yeast...
