Systems Biology: Interactomics Yeast were first identified by Pasteur around 1860 and the isolation and propagation of Saccharomyces cerevisiae soon followed. However, for over a hundred years, yeast were mostly isolated from wild fermentations and propagated based on their fermentative and organoleptic properties. Not until the 1990’s did we really start breeding or mutating yeasts … Continue reading Cider Words: Interactomics

Cider Words: Autolysis

Mālus Trivium Page Top

Autolysis: The decomposition of yeast cells. Why does the flavor of cider change when it ages? Part of those changes can come from bacteria or yeast. This micro flora can make malolactic fermentation (MLF) occur or a souring by Brettanomyces yeasts. However, one of the biggest impacts can come from the yeast that fermented your … Continue reading Cider Words: Autolysis
