I seem to always run high in my OG and I am not sure what to tweak to try and fix that. My pre-boil readings are pretty good but after a typical 60 minute boil I always end up high. My last batch was estimated at 1056 and ended up 1060 and if all else goes as planned the ABV will be 6.6% instead of 5.6%. Any idea on a good place to start?
