It's a good way to turn a huge polluted yeast cake into smaller, Yeast reproduce and go through genetic changes each time they ferment a batch of beer, so each time you reuse yeast it can undergo mutations that harm its fermentation performance and flavor profile. Eighteenth-century German braumeisters allowed the beer to ferment spontaneously with airborne yeasts, while today's brewers use lactic acid bacteria to give Gose its characteristic tartness. Oh, and there's a good reason to pucker up: Drinking Gose is rumored to heighten sexual performance. Zinc may be the only yeast nutrient that even barley malt is deficient of. Zinc levels greater than 0.6 mg/l can inhibit yeast growth (Priest, Handbook of Brewing). However, the performance of most yeast is restricted by temperature and also their alcohol tolerance levels. Various types of brewing yeast and distillers yeast are needed to produce the specified alcohols and spirits. In: Brewing Yeast Fermentation Performance. Only a handful still produce it, but the growing popularity of wild yeast and sour beers has sparked a renewed enthusiasm for the style among American craft brewers.
