Selecting And Generating Superior Yeasts For The Brewing Industry

October 25, 2013 By Jay Brooks

After my post a couple of days ago about Genetically Engineered Yeast, Chaz from Alaskan Brewing sent me a link to an interesting blog post by Dmitri, an amateur yeast wrangler who writes about his yeasty adventures at BKYeast. The post is a review of science literature from Cerevisia, the Belgian Journal of Brewing and Biotechnology. The article in question is titled Selecting and Generating Superior Yeasts for the Brewing Industry, which was published in 2012. It’s deliciously geeky and technical, but should be scrutable to anyone who brews either professionally or at home, thanks to Dmitri’s writing, as his goal is to take the jargon and science and make it accessible to a broader audience. As brewers struggle to have their beers stand out in an ever-increasingly crowded marketplace, it should be obvious that we’ll be seeing more and more experimentation with flavors and ingredients and ultimately more unique beers, and even new types of beers as others copy the successful ones, in the coming years. As the author notes, new varieties of hops are already facilitating that effort, and it seems likely that new strains of yeast are a logical next step in that evolution. And that’s what this research by a group from Leuven, Belgium is trying to make easier, finding the right yeast to create the right range of flavors for your beer. Give it a read.

“Graphical representation (heat map) of different characteristics of industrial yeast strains. Every row consists of data from a different yeast strain, every column is a different characteristic. ‘Yellow’ is a low score, and ‘red’ is a high score for this certain characteristic. The dendrogram on the left represents the genetic relatedness of the yeasts, based on an AFLP fingerprint exploiting transposon TY1 insertion site polymorphisms. The colour code on the top right indicates the origin of the yeast strains. This kind of analysis allows us to select yeasts with specific beneficial traits, for example to use in industry, or for breeding.”
