Hi. I am batch sparging and my efficiency is around 80% on normal gravity beers (1.040-1.050). I’m starting to suspect this is a little high, and that it causes some unwanted effects on the finished beer.
I’m using a plastic cooler with a manifold to drain. Typical mash temperature around 150-152 degrees.
Stupid question maybe, but how can I lower the efficiency? I would like to try to be around 70%. I have a MM3 set at max opening. I don’t have a refractometer. I don’t have mash tun space to do a no sparge. Suggestions?
