My target OG was 1.092-1.095 at 65% predicted efficiency (high gravity, I was definitely not overestimating). I hit 2 gallons exactly into the bucket, OG of 1.105!! (75%) I didn't use the bag this time, it worked perfectly though the bolt at the end of my hose fell out when trashing the grain, I'm 99% sure I through it away haha.. ah well, should probably grab a couple next time I'm at the hardware store, I'm guessing this is going to happen often.

I eased up the pressure on my mill and didn't "dust" the grain this time, just tried to crack it down to about 1/2 - 1/3 the size of a normal piece of grain. This gravity blew my mind, I'm still a little shocked it was such an efficient mash given the mad science recipe put together. That airlock was moving within 2 hours of pitching and when I looked this morning?? There is a full on war against sugar going on in that bucket.

Thanks for the grain advice, I followed it and it has returned extremely good results.

Great efficiency and no stuck sparge. Win Win.
