Maybe the guys who do 10 or more gallons will comment here, but I need an ABV calculator that will let me change the volume, instead of assuming the standard 5 gallons. Ive had more than a few batches that ended up with almost 6 gallons by bottling time and I need a more accurate way to calculating that abv. All the online cals seem to simply assume 5g, and Im not seeing a way to edit that volume.
