Cold‑room fermentation in ice houses used sub‑freezing temperatures to slow spoilage while allowing lactic acid bacteria to acidify foods.
Origin: Monastic communities, Scandinavian fishermen, English estates (pre‑refrigeration (medieval to 18th century)) — Europe
See full technique reference →At temperatures between 0 °C and 4 °C, homofermentative lactic acid bacteria such as *Lactobacillus delbrueckii* subsp. *lactis* convert lactose or glucose into lactic acid, lowering pH and inhibiting spoilage organisms. The process also produces CO₂, contributing to texture and flavor development.
