US is running out of aluminum cans

It's also surprisingly inexpensive to get started. Like any hobby you can spend as much money as you want, and supply stores will try to push you to the latest and greatest. But I think I'm going to remain happy with my simple siphon, pair of one gallon (~3.75L) glass fermenters, and glass bottles for a long time.
Also, for whatever reason the homebrewing community in the US seems to have standardized around the five gallon (19L) batch size, but there's nothing wrong with smaller batches. I like being able to have more than one kind fermenting at once, and the space to variety ratio is great. Who really wants five gallons of the same thing when you gave have a few gallons of different beers?
alcohol is absolutely essential - stress levels at peaking and I would never consider it a luxury at this point.
I guess being stuck at home, a 1/6 keg with a tap and CO2 system (which is less expensive than you'd think!) is the way to go -- with CO2 it should be ok for a few weeks to a month?
