推文好累...
如果包抹布與不包抹布
兩者的沖煮時間都控制在差不多的範圍內
喝起來會有明顯的差別嗎?
我以為不會
因為味道應該是受沖煮的時間影響較大
(如果不是的話請賜教)
再者
咖啡下流的速度會隨著粉的粗細程度而有明顯的不同
例如我用Rocky刻度10在不包抹布的情況下約30幾秒咖啡才會下完
如果用刻度20則20秒內會下完
顆粒越粗則包不包抹布在流速上的差異應該會愈不明顯
最後
板友提到的這個現象
farfree:特別是水快速下沖,最後還一直冒泡的的情況,我覺得超有趣
那是上壺的水蒸氣被吸入下壺後被冷卻
體積縮小(變成水)所造成壓力不平衡的現象
包不包抹布都會出現
有興趣的話可以做一個實驗
當下次上壺的咖啡開始下流時
你可以同時很努力地把上壺的水蒸趕跑(不停搧風之類的,要持續到咖啡流完)
那麼應該可以看到某種很不一樣的現象(笑)
