So I've done a few batches on my Mr Beer kit, and I'm deciding that this hombrew thing is something I'd like to stick with - but am looking for a better quality refill that works at a 2 - 2 1/2 gallon size for the LBK fermenter. I'm holding off on purchasing any additional equipment like kettles or all grain equipment, as I'll have more room for 5 gallon equipment next year. Right now my biggest pot is 2 gallons - What are my options for continuing at this size?
