Ok, a friend of mine gave me a wine barrel, and I want to use it to secondary some beer in and get some of the flavors from the sine and oak out of it.
Only problem is, it's 30 gallon barrel

, and I can't/don't want to afford a 30 gallon batch of beer.
My question is.........Could I place a plastic bag with 15-20 gallons of water in the bag tied off just floating in the beer to fill the barrel? That way I get the best of both worlds. Flavor without having to make 30 gallons of one type of beer. Would the bag survive? (I think it would)
