What is Yeast?

Yeast is a single cell organism which multiplies vigorously in the presence of oxygen and then after consuming all the oxygen will convert fermentable sugars into alcohol.  Without yeast we could not produce alcoholic beverages or ethanol fuel.

Distillers Yeast

Distillers yeast is a particular species of yeast (Saccharomyces cerevisiae) that has a particularly strong ability to metabolize sugar and produce alcohol as a by-product.  Distillers yeast also has a major impact on the flavor of your final spirit.  The flavor and aroma of whiskey, rum and moonshine (or lack of such in the case of vodka) are highly influenced by the distillers yeast in the fermentation process and thus choosing the proper yeast has a significant impact of the quality of your distilled spirit.  All distillers yeast is definitely not the same.
