It depends on how much wine you want to make. If it's a couple of
carboys of decent wine, then the suggestion of Oak Barrel is a good,
easy one. If you want to make a barrel of potentially great wine
(roughly 1/2 ton) then you've got a lot of options. I'd say that
www.winerysite.com had the best classifieds. Starting in June/July
there will many, many listings and if you're patient you can pick up
tremendous fruit.
