Today I did an AG stout with 9.25# grain, mashed @ 157 with 3 gallons.

I batch sparge with a converted 5 gallon cooler, I did 2 sparges, each 2.75gallons. The first sparge was 168 and the second sparge ended up being being 166.

I ended up collecting 7 gallons and getting about 5.5 gallons into the carboy (I only have 5 gallons marked off, so I'm just guessing @ 5.5).

Anyway, I ended up with OG of 1.051, which according to BeerSmith is between 88 and 89% efficiency.

Typically I only get around 83% using the same techniques.

The only new thing I did was using 5.2 stabilizer in the mash.

Does anything seem incredibly off? Too much sparge water, perhaps? I suppose I will find out in a few weeks if I screwed something up or not.

That's what the stabilizer is supposed to do.......increase your efficiency and keep the tannins out of your wort. I would think that the stabilizer did it's thing. I have soe ordered to try and can't wait to see it I can get in the 80's. I get in the high 60's right now....

If you ended up with the correct preboil volume, how could it be over sparging?

If your final runnings were under 1.010 extracting the unwanted prob because of a small grain bill.
