today i brewed my fifth all grain batch(3 gallon biab). it was the third time i brewed what is becoming my standard pale ale. i hit 73% efficiency. this is the highest i've been so far. today was also the first time i used my grain mill(a barley crusher), digital thermometer and o2 system. the crush right out of the box is pretty good. i think it's better than the crushes i've been getting at lhbs.
anyway, just wanted to share a good brew day. i'm super excited about continually dialing in and improving my process.
thanks for all the information everyone provides!
