Where can I buy a cheap fermenter?!
and i like walk-in stores, not online
Answers:
your best bet would be to buy a 1-3 gallon bottle of cheap wine (carlo rossi, etc)
then either empty it, or drink it... then get a rubber cap with a hole, and a $2 airlock, and you will be set.
update: if you have a 1 gallon jug, just go to a home brewing store, they should have some universal rubber stoppers that will fit it, and the airlock.... at most cost you $3 for everything
I'd suggest wandering down to a local homebrew store. If you want to use your 1G jug you'll be able to find a stopper and airlock to fit it.
While you're there pick up a copy of John Palmer's "How to Brew" it will walk you through every aspect of home brewing.
And FWIW - as long as you have good sanitation it's very unlikely that you'll have a "failed brew". The ingredients want to become beer and as long as you don't give other bacteria and nasties a chance, you'll get beer.
Remember: Clean; then Sanitize. 2 steps. Always.
