If you are looking for beers that are like sucking on a sour warhead, then look no further than Bruery's Oude Tart. True, it's a terrible beer, but definitely tongue-meltingly sour. It would be a waste of time for anyone. Oude Tart is an awful beer and certainly not worth $25. Pick up a 750 of Rodenbach Grand Cru if you want something sour that will have wide appeal. Wine drinkers will definitely approve of it's vinous characteristics, assuming they don't mind the sour.
