Hi everyone! I got a quick question, about conversion efficiency. I brew with a grainfather, and for a 10L batch you often have something like 7,8 L of mash water and then 8.7 L of sparge water. When calculating conversion efficiency, should the gravity be measured before or after the sparge...

Seems this is a fairly un-brewed style so far, it's not even in the style list! I figured i'd make a post and see if anyone has experience brewing Brut IPAs or anyone really could give this some feedback :) https://www.brewersfriend.com/homebrew/recipe/view/603096/brut-ipa-work-in-progress-...
