If you haven't read it, I would encourage you to review my overview of Pichia kluyveri and the other strains. Just search non-Saccharomyces on the site or look … Continue reading Non-Saccharomyces Yeast: Pichia Kluyveri Results
Cider Yeast: Classifications
Scientifically, yeast are identified by a classification methodology. They are part of the fungi kingdom and they will have different families and orders(1). For alcoholic beverages makers, like hard cider makers, we usually focus and talk about three classifications for yeast. The first and highest level is the genus. Saccharomyces is a genus of yeast. … Continue reading Cider Yeast: Classifications
