What You Need to Know
By exploiting the thermal sensitivity of lactic acid bacteria, yeasts, and other microbes, temperature dictates enzyme kinetics, substrate uptake, and by‑product formation. Lower temperatures favor acid production and preserve crisp textures, while moderate temperatures enhance ester synthesis and flavor complexity. Excessive heat can inactivate beneficial microbes, leading to off‑flavors or stalled fermentations.
The Science
Primary Reaction
Fermentation of sugars to acids, alcohols, and flavor compounds by temperature‑sensitive microbes
