Better still, why not have a go at brewing your own? Buy a 5 gallon beer kit
and if it turns out okay, bottle and drink it yourself. If not keep it for
the slugs and the snails. You'll have lots of fun brewing and they'll all
die happy if it all turns out unfit for human consumption.

A mix of a little yeast and a lot of water will work just as well and
is considerably cheaper. Ordinary baker's yeast, dried or fresh. Add a
little sugar to the mix and it will grow, so you can use even less
yeast.
