白茶冷泡科学：温度-时间-浓度的精确关系
White Tea Cold Brew Science: Temperature-Time-Concentration Precision
白茶冷泡的科学参数：4°C冰箱冷泡——茶氨酸在低温下持续溶出（0-4小时快速，4-12小时缓慢），而多酚和咖啡碱几乎不溶出。最佳参数：5g茶/500ml水/4°C/8小时=甜度峰值+零苦涩。室温冷泡（20-25°C/4小时）则多酚少量溶出，有更多茶味但略涩。冷泡vs热泡对比：冷泡茶汤茶氨酸含量是热泡的1.5倍（更甜），咖啡碱只有热泡的1/3（更不失眠），EGCG是热泡的60%（仍有保健效果）。冷泡白茶是夏天的终极方案。
White tea cold brew science: 4°C fridge cold brew — theanine continuously dissolves at low temp (fast 0-4h, slow 4-12h), while polyphenols and caffeine barely dissolve. Optimal: 5g tea/500ml water/4°C/8h = peak sweetness + zero bitterness. Room-temp cold brew (20-25°C/4h) has slightly more polyphenols, more tea flavor but slight astringency. Cold vs hot comparison: cold brew theanine is 1.5x hot brew (sweeter), caffeine only 1/3 (less sleep disruption), EGCG is 60% (still health benefits). Cold brew white tea is summer's ultimate solution.
