Cantillon is the only traditional lambic brewery located within the city of Brussels. Founded in 1900, today Cantillon operates both as a brewery and as the living [[Brussels Gueuze Museum]]. They use 100% organic grains and hops in all of their beers. Cantillon brews traditional lambic products, using 65% malted barley and 35% unmalted wheat. Their beers are spontaneously fermented using a large coolship in the attic and fermented in Oak barrels. Their flagship products, which are discussed further below, include:
