That being said I do already have 15 gallons fermenting or conditioning, as well as another 3-4 drinkable gallons of homebrew right now.
I have done 7 AG brews now and really feel comfortable in my technique, however my efficiency has not been very good (mid 60s). This leads me to believe that the crush from the HBS that I have been ordering (MoreBeer) is not adequate, and also inconsistent. I have been using my pre-boil efficiency to calculate a DME addition to get closer to my OG which has worked, depending on how my efficiency has been. I am thinking a mill will allow me to not only jump my efficiency to 75-80% but also give me consistent results.
