我想學英文 wrote:
每當豆量減少到約剩三分之一時,粉就會變細,
咖啡機萃取的秒數也會增加;
當豆槽又重新裝滿時,粉變粗,萃取秒數就減少,
但過了幾把之後就會恢復正常的粗細,不會太粗或太細...(恕刪)
還是回到正題吧
我想請教樓主,以上這段敘述,已經證實確定是豆槽豆量的影響嗎?
我的意思是,排除一切可能因素,如早晚溫差,溫溼度,粉量,豆子待在豆槽裡的時間等
例如用電子秤量粉重,先在豆槽豆量近全滿時做一杯
然後立刻把豆子倒出來留下三分之一以下,再以相同重量的粉做一杯
觀察記錄這兩杯的流速
國外有位大師說
It's a well known fact that the the grind setting needs to be finer when grinding few beans, either when single dosing or when the hopper is near empty. This occurs because with fewer beans in the burrs at any one time, there is less bean to bean crushing action. To get the same fineness, the grindstones have to pick up the slack; and they do this by being closer together.
撇開變粗還是變細不談
國外是有很多人覺得把豆槽裝滿,出粉的一致性會比豆槽豆量少或single dosing要好
