I've been all grain brewing for over 10 years now and have lived with a 7.5 gallon pot and doing the boilover dance many a time. I've actually gotten good at it. A buddy gave me a 15.5 gallon stainless keg which I cut the top off of and now I have a keggle. I like the headroom in the keggle, but it is so heavy (no port) to lift and seems like I'm wasting a lot of propane because of the thick sidewalls on the bottom. I'm thinking of buying a brewpot. I have zero plans on ever brewing anything more than 5 gallon batches. a 15 gallon pot seems a bit much, but will I have only marginal benefit on boilovers with a 10 gallon pot? or will I be in good shape? All the posts seem to point to 15 gallon pots, but its always with eye to brewing 10 gallon batches at some point...I just want to do 5 only. I use a cooler for mashing, so not issues with using it as a mash tun.
