for those that may be near me (huntington WV) there is a local business that sells among other things(flowers and trees) blue food grade barrels..they are $12 a piece and the ones i saw had either cider vinegar or kikioman soy sauce in them according to the label.. i was also hoping to see a label with a local address on it so i could get a source but no luck..he may have them trucked in from the place in MI and WI that was on the labels because at the begining of the summer he has like 100 of them sitting around.. i bought 2 and rinsed them out with plain water and some baking soda..soy sauce has a very strong smell after sitting in a barrel for a while..
