Ok, I made a mistake on my calculations last month while doing my first double batch of beer and ended up adding 2 extra gallons of sparge water. Post boil amount ended up only one gallon high and my OG wasn't really all that far off.
My question is, what should I expect from this over sparge? Now that it's almost through with fermentation, it tastes a little sour. I only ask because I'm debating bottling 120 beers or half that and then kegging the other half
