Lambic is a distinctive type of beer brewed only in the Pajottenland region of Belgium.
Unlike conventional ales and lagers, Lambic beer is produced by spontaneous fermentation by being exposed to wild yeasts and bacteria. It is this unusual process which gives the beer its distinctive flavour: dry, vinous, and cidery, with a slightly sour aftertaste.
Many Belgian fruit beers have Lambic as their base for blending with cherry (kriek), raspberry (framboise), peach (pêche), blackcurrant (cassis) or strawberry (aardbei) as either whole fruit or syrup.
