Fermentation
Beginner Winemaking & Viticulture定義
The conversion of grape sugar into alcohol and CO2 by yeast.
詳しく
The fundamental transformation of grape juice into wine. Saccharomyces cerevisiae yeast metabolizes glucose and fructose, producing ethanol, carbon dioxide, and heat. Temperature control is essential: 12-15°C for aromatic whites, 25-30°C for red extraction. Fermentation typically takes 1-3 weeks. The process also generates hundreds of secondary compounds that contribute to wine's complexity.
