Is it possible to do a 10gal BIAB? I have a keggle, my thinking is that approx 12gal of liquid would hold a steady mash temp better than say 3-4 in a 5 gallon batch during the mash. If I have the bags and space in my keggle, as well as compinsate for efficiency loss without a sparge(add more grains) would I be losing anything other than effinciency?
