I'm having a hard time deciding on what size Boilermaker pots to use in my electric setup that I am working on. Currently I only brew 5 Gal batches and right now do not have the storage space for 10 Gal but I am sure I will do it someday. If I decide to go with the 20 Gal Boilermakers has anyone had any major issues brewing 5 Gal batches? I know the Brewmometer will not reach as it is placed at about the 9 Gal mark. Is there any other issues besides that that I should be aware of?
