咖啡豆研磨得越细，味道就越浓？其实不完全是这样！
Grind finer = stronger flavor? Not always! There’s more science behind it than you think.
📏 咖啡研磨的五大常见粗细度
5 Common Grind Sizes & Their Uses
| 中文 | 英文 | 建议用途 |
|---|---|---|
| 极细研磨 | Extra Fine | 土耳其咖啡 |
| 细研磨 | Fine | 意式浓缩 (Espresso) |
| 中细研磨 | Medium-Fine | 手冲、爱乐压 |
| 中研磨 | Medium | 美式滴滤、自动咖啡机 |
| 粗研磨 | Coarse | 法压壶、冷萃咖啡 |
⚖ 研磨度 vs 萃取时间
Grind Size Affects Extraction Time
研磨越细 → 接触面积越大，萃取更快
Finer grinds = faster extraction, higher risk of over-extraction (bitterness)研磨越粗 → 接触面积小，需更长时间萃取
Coarser grinds = slower extraction, but may under-extract if too quick (sour taste)
☕ 如果选错了研磨度会怎样？
What Happens If You Use the Wrong Grind Size?
过细粉 + 滤杯冲泡：水流变慢，咖啡过萃太苦
Too fine in a dripper? Water slows down, bitter over-extracted brew.太粗粉 + 意式机：水几乎冲不出味道，变成酸水
Too coarse in an espresso machine? Water flows too fast = under-extraction.
📝 小建议：
Tips for Home Brewers:
没有磨豆机？可选择店家代磨（记得告知冲煮方式）
No grinder? Ask your roaster to grind based on your brew method.不同冲煮法请准备对应粗细度
Different brewing methods need different grinds—don’t use one size for all!使用手磨机时可多试几次，找出最适合你口味的“研磨点”
When using a manual grinder, experiment to find your ideal grind setting.
