指#44的... If you're looking for clarity, one of the better ways (in my personal experience and on my setup of course) is to allow faster flow with less preinfusion, and pull to a high brew ratio...嗎?
這段我存疑。經驗中有發生過這種事,但認為是剛好豆子很容易應付,簡單處理就可以。
dc碰風啥的我不介意,反正我不會買。結果是看完整串,matt perger那句...A lower bed depth makes it easier for channels to form (M Petracco, 2005). ..還是無解。

Best book currently available for the guy that wants to know more but its not for average browsing. Covers espresso coffee from origin to cup. Doesn't give a scientific answer for every question which says to me that there are still aspects that are "art" and not yet fully explained. The book I was looking for hasn't been written yet (to my knowledge). Maybe it never will be.
