I'm soon to up my batch sizes for my 'house amber' to 20 gallons, I found a kettle but I'm contemplating the fermenter. I can use 4 6.5 gallon carboys or I can get a 30 gallon drum. I know there is some argument over oxidation through plastics but I'm wondering if its actually all that noticeable. I'd love to get a stainless, but that just isn't in the budget right now. The drum has a 3/4" hole for an airlock / blow off hose and I'm figuring I can use a bulkhead for a drain and just build a stand thats higher than my kegs to drain it. Being that I use a bathroom in the basement to ferment in (stays <70 all year for ales) my wife may kill me. I do have a home office that I could do this in with less risk to my health.
I know I can fit the carboys in the bathroom and they're individually easy to move around and clean. I'd probably have to use a 5 gallon bucket to fill the drum. Anyone doing / contemplating anything similar?
