3 Fonteinen was founded in about 1887 as a café and geuzestekerij, a place where geuze is produced by blending old and new lambics, acquired from other breweries. The enterprise was bought by Gaston De Belder in 1953, who expanded it with a restaurant and left it to his sons Armand and Guido in 1982. In 1998, a brewery installation was bought. Apart from using its own lambic, 3 Fonteinen uses lambic made by Boon, Girardin and Lindemans for its geuze. 3 Fonteinen is one of the few remaining geuzestekerijen. The Mijol Club, a literary club, founded by Herman Teirlinck, used to convene in the café.
