Cryogenic preservation uses ultra‑low temperatures to halt microbial and enzymatic activity in fermented beverages.
Origin: Japanese sake breweries and European microbreweries (Modern era) — Japan and Europe
See full technique reference →At temperatures below –80 °C, metabolic reactions are arrested, preventing yeast, bacteria, and mold proliferation. Rapid freezing (>10 000 °C s⁻¹) limits ice crystal growth, preserving cell integrity and volatile aroma compounds. Maillard reactions are effectively stopped, though limited lipid oxidation can occur if oxygen is present.
