Description
Yeast flocculation: a FERMENTATION culinary technique.
Technical
Yeast flocculation typically refers to the reversible clumping together (flocculation) of brewing yeast once the sugar in a wort has been fermented into beer. In the case of "top-fermenting" ale yeast, the yeast creates a krausen, or barm on the top of the liquid, unlike "bottom-fermenting" lager yeast where the yeast falls to the bottom of the brewing vessel.
