The Very Yeast

March 4, 2016 Artvoice 0






Of the 1500 or so species of yeast, only about 300 of these are species that can ferment sugar. However, very few of these 300 are able to produce reliable concentrations of alcohol. Because alcohol is toxic to cells, yeast will die as they ferment and the concentration of alcohol increases. Only a handful of strains have been discovered that can sustain alcohol concentrations of greater than 8 percent.
