Out of pure curiosity, is there a manual canner for sub-nano brewer?
There's no such thing as a truly "manual" canner. The seaming is a fairly complicated operation and there's really no way around that. I guess that at really tiny volumes you could fill the cans using a simple siphon setup and then seam them, but most people seem to end up with
Cask's two-head filler. Until Wild Goose came on the market, anyway. I guess we'll see what happens now.
Or a better question would be, how many cases of bottles (production level) until switching to cans makes sense?
Economically, a semi-automated canning setup is actually less expensive than bottling, in both capital and per-unit costs. The two
Cask units, gently used, sell for about
half a minivan
