First AG

I brewed my first AG last night ... went pretty well. A little disorganized, but I will work on that.

The brew was supposed to be a SA Cream Stout clone I found, but I used a different yeast, and some different hops ... so basically it's a stout.

I was aiming for a 5.5 gallon batch, but came up with 5.25 .... not too bad. I was also aiming for a OG of 1.054 at 5.5 gallons, assuming 65% efficiency ... but ended up with 1.064 at the 5.25 gallons. I didn't have enough room for all of my runnings, but I took the gravity of the last little bit, and the gravity was 1.032 .... should kept sparging for another batch I guess.

But here is my question ..... could someone help me calculate my efficiency??
Here is the recipe:

Like I said, I missed the Batch size, ended up with 5.25 gallons, and the OG was 1.64.

(edit, had 6 row instead of 2 row, so my first # of 82% was wrong.)

congrats on the first AG! looks great.

I may have an issue with this batch. I mashed high, 158 ... I wanted it big bodied. It fermented down to 1.030 and has been there for a few days, I pitched some s-04 hoping to bring it down farther ... but 2 days and nada.

Would mashing this at 158 be the cause of the high fg 1.030?? or should it have a lower fg??

It should probably get a bit lower. Try brining the temp up to ~70 and see if it kicks up again

S-04 is not all that attenuative. One time I had S-04 not finish up a ferment and I added S-05 and that finished it up.
