I heard grain crush significantly affect efficiency. I have done 6 all grain brews (of 24 total) in a Mash & Boil. First and third were so so. Second was bad (low mash temp & stuck). But this month I did three. All three were off in OG with the first one way off. My LHBS crush them for me. I want to show pictures to see if you can tell me how they look. All for 5gal batch. Final OG at fermenter with 4.5-5.2gal. Below are pictures. Tks
First one was a stout. OG was 1.052 and got 1.032 (5.2gal) Fly sparge with water over spoon
Second was a honey blossom ale. OG was 1.045 and got 1.41 (4.5gal). Batch sparge.
Third was a brown ale with OG of 1.066 and got 1.045 (5 gal) Batch sparge.
