先感謝scorpioliu b101300290 Icta trouk等大大的分享

魚博士 GH/KH test kit google sheet試算 https://bit.ly/40YbpUQ
→ b101300290: 也可以用KH/GH值比比看(水族館也有test kit可以買) 02/13 15:37
→ b101300290: 一般來說GH跟整體風味萃取有關,KH有點算是鹼性/buff 02/13 15:37
→ b101300290: er,太少咖啡液喝起來酸度會提高;太多就中和掉整杯 02/13 15:38
→ b101300290: 咖啡的酸味會很平淡 02/13 15:38
→ Icta: 一般咖啡沖泡來說,比較在意水的alkalinity,作為buffer 02/13 17:43
→ Icta: 對於咖啡風味普遍認為有著比PH更大的影響 02/13 17:44
→ Icta: 所以一般會用滴定法去測定kh值來了解水質的鹼度 02/13 17:44
→ Icta: 現在國外談水質,主要滴定出GH跟KH來決定,細部再談鎂鈣比例 02/13 17:45
→ Icta: https://reurl.cc/Dm1Y1d 02/13 17:49
→ Icta: sca就談過,為什麼在咖啡萃取上鹼度比酸鹼值更重要 02/13 17:50
→ Icta: 很粗略去談就是GH決定萃取強度,KH決定風味展開,鈣鎂比決定 02/13 17:54
→ Icta: 風味取向 02/13 17:55
→ Icta: 水質挖下去恐怖的地方在於會發現手法跟刀盤的差異會被抹殺 02/13 17:56
→ Icta: 調水質會發現可以把乾淨的刀調到有夠雜,把雜刀調到溫和 02/13 18:00
→ Icta: https://reurl.cc/WD4zM7 Gagne有寫過水質的基礎 02/13 18:13
→ Icta: 但這篇有點舊了,水質陸續有新的概念出來 02/13 18:16
→ Icta: https://reurl.cc/0Ezk8M 這篇很有趣 02/13 18:20
→ Icta: 是一位玩家與ssp mp刀, tricolate與水質混戰的血淚 02/13 18:21
推 scorpioliu: 只是純水或RO+瀉鹽+小蘇打的話,我的經驗咖啡會偏平 02/15 09:03
→ scorpioliu: 板呆滯頻寬窄,要活潑細節多一點要多點不同離子,可 02/15 09:03
→ scorpioliu: 以增加、鈣、鉀、氯化鎂,也印證有人喜歡天然水較豐 02/15 09:03
→ scorpioliu: 富的表現 02/15 09:03
推 trouk: 我自己配鈣、鎂、鈉濃縮配方液,也只有一開始調配時稍微麻 02/14 22:07
→ trouk: 煩一點點(三罐濃縮液調15分鐘吧),後續使用只要花錢買一 02/14 22:07
→ trouk: 支微量滴管(陸製max 10cc 1000元左右),沖煮時就非常簡 02/14 22:07
→ trouk: 單了,還可以很輕鬆的調整3種離子濃度,操作容易調整自由 02/14 22:07
→ trouk: 度又高 02/14 22:07
推 trouk: 目前心得,最後沖煮水常溫時的TDS大於80跟我都不怎麼合, 02/14 23:19
→ trouk: 目前最常用的是AQUACODE 9L配方的離子比例,鈣3.5ppm/鎂12 02/14 23:19
→ trouk: .1ppm/鈉0.4ppm,目標tds 66,我自己計算調配後弄出的沖煮 02/14 23:19
→ trouk: 水tds也是64-70之間,剛好檢驗出我沒有算錯XD 02/14 23:19
原子量: H:1.008, O:15.999, S:32.065, Na:22.99, Mg:24.305, Ca:40.078, Cl:35.453
分子量: CaCl2:110.984
MgSO4:120.366, MgSO4.7H2O(epsom salt):246.47
NaHCO3(baking soda):84.007
trouk大配方水:
3.5 ppm Ca -> 110.984*3.5/40.078 ppm CaCl2 = 9.69 ppm
9.4 ppm Mg -> 120.366*9.4/24.305 ppm MgSO4 = 46.55 ppm
0.4 ppm Na -> 84.007*0.4/22.99 ppm NaHCO3 = 1.46 ppm
TDS = 9.69+46.55+1.46 = 57.7 ppm
SCA optimal recipe:
16.5 ppm Mg -> 120.366*16.5/24.305 ppm MgSO4 = 81.71 ppm
18.4 ppm Na -> 84.007*18.4/22.99 ppm NaHCO3 = 67.23 ppm
TDS = 81.71+67.23 = 148.94 ppm
原來SCA optimal目標TDS要150左右 一直跟total hardness搞混了@@
如有漏掉請幫忙補充一下~
