I've posted about getting better efficiency before, and I've always applied the suggestions to the equation. I have a manifold that covers about as much as the bottom without it being a false. I have a sparge arm that very slowly and evenly distributes. The only question I have.
Does anyone FLY sparge with a rectangular cooler? If so, do you use a manifold, and Sparge arm? If so, would you please post a picture of your system and your average efficiency. Just curious whether I should bag fly sparging with a rectangular cooler or if my system is missing something. I don't know why, but i really want to nail fly sparging.
I understand the million variables. Just want to see your system. Want to know I'm lautering as best i can before I worry about some of the other variables. I already sparge for 30 to 45 minutes with my PH between 5.2 and 5.6
