Lambic is a traditional beer style that has its roots in Brussels and the region of Pajottenland. This style must be made with a minimum of 30% wheat, and the wort is always spontaneously fermented with local and naturally occurring wild yeasts.
Because of different local microorganisms, these beers always have a unique and frequently unpredictable character. Due to its wild nature, many batches of lambic are sometimes blended, a style known as gueuze or geuze, to produce a more palatable version.
Although it is difficult to pinpoint the exact characteristics of lambic beers, the unblended young varieties are usually pale with a characteristic red sheen, while more mature versions will usually have red to light purple color. These beers are always complex, and they often have a distinctive sour backbone, which will mellow as the beer ages.
Most styles will display fruity aromas and flavors, with subtle malt character, dry finish, and little hop bitterness. Lambic beers are mostly enjoyed young and uncarbonated, and they will usually be served on tap. They pair well with seafood, especially mussels or oysters, and poultry.
