I'm currently in the process of setting up an electric rims set up. I currently have two keggles that I want to use, one for BK one for MLT. It would be convenient if I could just use a 2 vessel no sparge set up but I'm concerned with volume as I fairly often make some vary large beers, imperials and barleywines. I'm just not sure if I can fit all everything in one keggle when making something that has an OG of like 1.120. Any advice on a good compromise to keep this a two vessel system would be much appreciated.
