The duration of refrigerated retardation in sourdough baking significantly impacts the final product’s characteristics. This process involves slowing down yeast activity through reduced temperatures, typically ranging from 35F to 45F (2C to 7C), after an initial period of bulk fermentation. The time spent in this chilled environment can vary widely depending on factors such as the starter’s strength, the recipe’s hydration level, and the desired flavor profile.
Extended periods at low temperatures develop complex flavor profiles and improve dough handling. Slow fermentation produces more organic acids, contributing to the bread’s characteristic tang and enhanced keeping qualities. The prolonged resting period also strengthens gluten development, leading to a more open and airy crumb structure. Historically, cold fermentation was a practical method for managing dough in environments without precise temperature control, allowing bakers to work around their schedules.
