I have been brewing all grain for a few months now but am ready to upgrade. Ive been mashing on my stove top in a one gallon stock pot and sparging using a strainer. My capacity per brew is stuck at one gallon at the moment. My question is what is the best way to upgrade to a five or even ten gallon setup (do you think five is big enough or should i just jump to ten?) Whats the best and cheapest way to get a brew pot, lautering tun and all that stuff going. Whats your recommendation as far as carboys go? My goal is cheap, big, and not making too big of a mess (eliminating spills). I already have a turkey frier setup and access to every power tool imaginable (lathe, drill press etc.) so a little DIY is no issue. I'm mostly brewing simpler ales with some experimental batches thrown in here and there. Basically whats my best investment at this point? I would love to be self sufficient and be able to brew all the beer I drink (not that I would, but that I could).
