Description
Extended yeast fermentation at 4°C slows metabolism to favor flavor development over gas production.
Technical
Cold retardation slows Saccharomyces cerevisiae activity while allowing endogenous enzymes (proteases, amylases) to hydrolyze proteins/starch into flavor precursors (amino acids, maltose).
Culinary Significance
Creates superior crust color, complex aromatics, and extended shelf life in breads.
