I read a simple article on beertools about over milling resulting in astrengency? How much is overmilling? I mill my own at the LHBS and it is a very nice crusher that is the the double roller powered by a drill and the speed you run it through can affect the crush. Thinking "oh the better the crush the better the efficiency," i run my grain nice and slow and get a very nice crush with efficiency around 80% batch sparging with the steel braid. I have never got a stuck sparge, but i am getting astrengency in some of my lighter beers (i realized i was over sparging and hope thats that problem). My real question is it possible to really get off flavor from over milling or should i not worry about it and just keep doing what im doing
