Genome sequencing of traditional kveik yeast used in farmhouse brewing on the west-coast of Norway
Kveik is the common name of yeast that has been used in traditional farmhouse brewing of western Norway for generations. Its fast fermentation, increased flocculation, temperature tolerance, and rich flavor profile have led to growing interest in recent years. Previous genetic analyses have shown that kveik forms a distinct group within the Saccharomyces cerevisiae tree and placed its origins within the Beer I clade of industrial brewing yeasts, although with signs of mixed ancestry. In this study, we revisit the phylogenetic position of kveik within the S. cerevisiae tree. We searched for traditional farm breweries in western Norway and collected ten samples of potential kveik yeast.  Using Illumina whole genome shotgun sequencing, we aim at determining specific variants associated with kveik and determine its phylogenetic position within the S. cerevisiae tree.
