So I am having trouble locating some small used oak barrels (most of the barrels I can find are 50 gallons and I can't use something that large). What about using something like http://www.thenewenglandtradingcompany.com/solid-oak-barrel-drink-dispenser/ to age beer in? It would fit about half of a batch of beer. that way I can compare the aged beer to non-aged beer.
