※ 引述《mechtec (小豆)》之銘言:
: ※ 引述《jimmyw1003 (jimmywow)》之銘言:
: : 各位大大好小弟初學者接觸手沖三個月,想要問各位前輩們關於濾杯的意見
: : 就小弟淺見分析kono濾杯迷人之處是在於它對咖啡粉均勻萃取的程度,短溝槽設計所形成
: : 的壓力造就它的萃取方式,爬了一些文發現比較少人深入介紹所謂的點滴法,但目前坊間
: : 咖啡店點滴法因為費時耗成本的關係,又比較多是用普通手沖方式注水繞圈的方式,跟當
: : 初的設計理念不太一樣。
: : 雖然萃取方式取決於沖咖啡的人,但還是想要看看前輩們有沒有對kono濾杯獨特的見解或
: : 是針對點滴法與普通手沖去萃取咖啡出來風味的差別?
: 我在推文處問了原po,Kono與其他手沖法最大不同之處
: 你注意到了嗎?
: Kono最大不同處就是水是慢慢浸濕咖啡粉,慢慢的萃出來
: 咖啡豆烘焙好,裡面的水分會喪失一些
: 整個結構就變成了一種多孔性材料
: 加上梅納反應還再繼續作用
: 這裡面的二氧化碳還在繼續排出
: 所以第一次注水時,高溫熱水一沖下去,更加刺激二氧化碳大量噴出
: 水不容易進入到多孔性結構裡面(一個衝出來,一個想進去,會打架)
: 因此會用悶蒸手法,先讓一些二氧化碳排出
: 接下來的注水,水才容易進去
: 此外,注水有分1.大量的、高處注水,以及2.小量的、低處注水
: 1的情況,就是讓粉體翻攪(沖)
: 2的作用,則是讓粉浸潤(或說浸泡)在熱水中(泡)
: 適當的分配1與2 <--這就是手法喔!
: 這兩者都可以讓萃取率提高(但是味道有一點不同喔)
: (所以,葉教授才會在FB上說:誰再問我水粉比,我就翻臉)
: 濾杯上肋的作用,最主要不是什麼壓力、虹吸作用...balabala
: (我知道你看了哪一本書了....XD)
: 而是濾紙與肋的貼合處,產生毛細作用
: 使得萃取出的咖啡液體能夠順利的向下排出
: 不會產生堆積
: 過度堆積,在某些沖煮手法與濾杯的使用上,會容易產生過萃
: 同時也引導水流的方向 <--很重要喔
: 當然,因為這樣,咖啡的新鮮度、粉的粗細
: 甚至咖啡豆的產地、批次...,都會影響使用的濾杯與手法
: 所以,你可以綜合我上面說的
: 來看看V60與梯形濾杯(無論是單孔或三孔)設計
: 是否看出這兩種濾杯所對應的手法,為何有所不同?
: 再來看看kono
: 不用悶蒸,慢慢的滴
: 二氧化碳應該一樣排出,不是會造成前面說的阻擋熱水進去多孔性粉體內嗎?
: 為什麼在kono手法上比較看不到這樣現象?
: 想想看,咖啡粉的烘焙度有沒有不一樣?
: 粗細有沒有不一樣?
: 慢慢滴,時間拖那麼長,為什麼不會過萃?
: 所以kono濾杯的肋為什麼那麼短?而且也少?
: 附帶一提
: 我看到上面P網友寫的
: 也跑去某邪惡連鎖咖啡店去聽他們的手沖課
: 他們豆子是有名的深
: 而且都是保存期限半年以上的那種商業豆
: 用V60,磨得很細
: 然後悶蒸5秒,接下來就用小水柱只注水在中間
: 慢慢沖3分鐘(還是2分30秒,我忘了,反正比我們平常用V60手沖時間長)
: 有沒有有一點kono的feeling?
: (後話:其實那家邪惡咖啡店總公司還是有人懂手沖
: 不然不會用這種比較特殊的手法
: 只是教育訓練不足,員工只知其然,不知其所以然)
: 給大家參考
「何方神聖」一詞對誰都不該這樣說,恕我失言。
會這麼衝動的說是因為我認為對如何沖出一杯好喝的咖啡,正確的方法、正確的道理到哪裡都是通的,而不是因為哪個大師曾說過什麼就代表那是正確的。
先謝謝小豆大(如果不嫌棄我這樣稱呼)給大家一些思考的空間。
首先有個前提是kono跟V60在形狀上有很大的差別,為此我們可以用他們達到不同的沖煮效果,這個是肯定的。
不過我認為小豆大的說話的方式太玄、太讓人難以理解。
我對肋的效果還是存疑的
原因是這樣:一般所謂的KONO沖法都是從中間滴水下去,待粉層徹底把水分吸足了後因承受不住往下滴,按照錐形的粉層結構來看,如果水確實沿著肋滑下去,那不是代表有部分的水沒有完全經過粉層,而且先從頂部到達了濾杯邊緣,再沿著肋滑下?
事實上咖啡液會從哪個位置離開粉層是未知的,所以儘管可以觀察到咖啡液沿著肋條往下流,也不代表底部滴下的咖啡液一定是由肋條而來,而亦可能是直接一路穿過粉層往下。
是的,不同構造一定會有不同影響,但影響多少?如果只有5%的咖啡液會沿著肋條往下,那它還是我們調整的重點嗎?這個答案是未知的,甚至還有更多的因素在其中作用。
於是我認為最關鍵的因素應該還是由孔洞大小造成的流速差異。
再來小豆大也提到過翠的問題,我認為你簡化了太多因素,只看手法並不是很恰當。如果你直接用滾水開始滴還不會過翠嗎?如果你把粉磨到義式的程度呢?
翻攪、浸泡,就不用顧及粉水比了嗎?當你調整操作變因時,一定要考慮控制變因,那應變變因才有意義。
唉,說到底好喝才有意義啦
