Well, I brewed the IPA clone last night and it is not much of a clone. I sucked on my effiency. I know the BYO recipes are based on 65%, so I thought I would be safe if I increased the volume from 5G to 5.5G with the same grain bill thinking I could get above 70% efficiency, but that didn't happen.
My preboil gravity (SG) was 1.044 with a 7.5G volume. I ended up only boiling for 80 minutes with a very slow boil because it was burning off quickly.
My OG was 1.056, but I think I have a little more than 5.5G in the fermentor.
I Mashed at 150 for 60 minutes with 4.25G (17Q), I drained 2.6G, and batch sparged with 3 gallons on the first run and 2.5G on the second run.
I should have used less sparge water. After I got my boil volume and drained the cooler to see how much was left and there was close to another gallon left and I am wondering if I used 4.5G / 2 sparges instead of 5.5G I would have had a higher OG. The water would have been more concentrated it seems.
What do you think? Beer smith calculates my brewhouse at 62%
