Incomplete Fermentation
Cause: Temperature fluctuations above 4°C activate yeast prematurely, while temperatures below 0°C halt all microbial activity
Fix: Use calibrated refrigeration with ±0.5°C precision and thermal buffer materials
Excessive Acidity
Cause: Prolonged cold fermentation (beyond 72 hours) allows lactobacilli to dominate, producing excess acetic acid
Fix: Limit fermentation to 60 hours maximum or introduce 1-hour room temperature proofing phase
