Alcohol Sanitization
Alcohol sanitization
Japanese: アルコール消毒（あるこーるしょうどく）
Sanitization by wiping surfaces with ethanol to eliminate unwanted microbes.
Food-grade ethanol (70-80%) applied via cloth or spray eliminates surface microbes. Too high concentration evaporates too fast — 70-80% is optimal.
Sanitize container interiors, lids, spoons — everything contacting miso. Hands too. Alcohol evaporates with no residue — the most convenient home fermentation sanitizer. Keep alcohol in a spray bottle for instant access. Line up tools before preparation and spray each in order. Cleanliness builds confidence in your fermentation.
