根據您這個情況再回想(恕刪)
魚大好，最近在ditting usa買了一組807的刀盤裝在KF804上，送來標示是804的刀盤，提供給您參考。

您好
感謝您提供資訊
原來刀盤可以直接跟ditting USA買
剛收到Voltage Coffee Supply的回覆如下：
We believe the 804 Lab Sweet are the same discs as used in the 807 Lab Sweet, but we won't know for sure until the first units get here for us to play with.
也收到ditting USA的回覆如下：
I *believe* the 807 Sweet discs are the same as the 804 Sweet discs, but we will wait for our first shipment of the 807s to arrive in the next week or so to confirm and compare.
The U.S. is the last market to receive the 807 series grinders because the certifications required here are very strict and a much lengthier process.
結果總算出來了
等了大半年，內容有夠少
而且萃取率高低拿出來單獨看也不重要，如果有粒徑分布資料搭配看才會比較有意義
希望接下來還有其他內容會公布
第三張圖裡的Espresso TDS不知道為什麼會是2.12和2.11
Espresso的參數可能是這個

但是804 LS的刻度從1起跳，根本沒有0.7

後來Socratic Coffee解釋
第三張圖表中，他們是抓一個類以espresso與filter的粗細度去做某種方式的萃取得到的數值
並不是真的去做espresso與filter萃取
目的是要比較出兩台磨豆機磨出來的咖啡粉在相同條件下的溶解度的差異
the espresso "equivalently sized" particles were taken from a sieve stack with grind particles between 354 and 297 microns (US Std No. 45 & 50). The filter samples between 707 and 595 microns (US Std No. 25 & 30). We used our validated sieving protocol to get these particles and then test them in our solubility protocol to see if "similarly sized" particles (where the only variable is the grinder that produced them) extract similarly.
測試時的萃取方法可能是他們先前po的這篇吧
