Westvleteren Brewery
Until 1999, the brewery also made a 6.2% ABV dark beer and a lighter 4° which was the monks' table beer. The 8 and 12 are bottle conditioned.  They have a long shelf life. Some drinkers prefer the taste when the beers have been stored for several years. The ingredients are yeast, hops, malt, sugar, caramel and water.
