Lambic is a type of beer brewed in the Pajottenland region of Belgium southwest of Brussels and in Brussels itself at the Cantillon Brewery.
 Lambic beers include gueuze and kriek lambic.
 Lambic differs from most other beers in that it is fermented through exposure to wild yeasts and bacteria native to the Zenne valley, as opposed to exposure to carefully cultivated strains of brewer's yeast.
 This process gives the beer its distinctive flavour: dry, vinous, and cidery, usually with a sour aftertaste.
