Drie Fonteinen is one of the traditional lambic brewers/blenders out of Belgium. They are located near Brussels in Beersel, BE. Gueuze is produced by blending aged and young lambic. Kriek is similar, except that cherries are included. This 375ml beauty is incredibly tart and sour, while still being drinkable and interesting! I love this beer and always buy it when I see it on the shelves, even though it is not a cheap purchase.
