✅ Detailed Explanation
- Catechins & EGCG → Heat helps them extract faster, but they’re stable in cold water too.
- L-theanine → Heat-resistant amino acid, not destroyed by cold.
- Caffeine → Fully soluble in hot and cold.
- Taste → Cold whisking = smooth, creamy, refreshing. Warm whisking = stronger umami, more “traditional” feel.
📊 What the Science Says
- Food Chemistry (2018): Catechins stay stable at 10°C (cold) and 80°C (hot).
- Journal of Food Science: Cold-brewed green teas — including matcha — still deliver antioxidants.
- Consensus: You’ll get benefits either way. Hot water is faster, cold water is smoother.
⚖️ Cold vs Warm — Pros & Cons
| Cold Whisking | Warm Whisking |
|---|---|
