History
Lambic has been brewed in the Senne Valley and Pajottenland, southwest of Brussels, for centuries as a farmhouse tradition. In the 19th century blenders began bottling mixtures of young and old lambic, producing the sparkling gueuze, and adding cherries (kriek) and raspberries (framboise). The number of producers fell sharply in the 20th century. Cantillon (1900), Boon, Drie Fonteinen, Lindemans, Oud Beersel, Girardin and Timmermans survive, and the High Council for Artisanal Lambic Beers (HORAL) was founded in 1997. 'Oude geuze' and 'oude kriek' are protected as EU Traditional Specialities Guaranteed.
Appearance, aroma and taste
Unblended lambic is pale yellow to gold, often hazy and nearly flat, with sour, earthy, barnyard, hay and citrus aromas. Gueuze is deep gold, sparkling, with a lively white head and complex aromas of lemon, green apple, leather, horse blanket and oak. It is intensely sour but dry, with almost no hop bitterness. Kriek is ruby red with tart cherry and almond notes from the stones; framboise is pinkish with raspberry aroma. Traditional 'oude' versions are unsweetened, unlike modern sweetened commercial lambics.
How it is brewed
The grist combines about 60 to 70% barley malt with at least 30% unmalted wheat, mashed in a long 'turbid' process. Brewers use aged, low-alpha hops for their preservative effect rather than bitterness, and boil for several hours. The hot wort cools overnight in a shallow open vessel called a koelschip, where wild yeasts and bacteria from the air inoculate it, mainly in the cold months from October to April. Fermentation in oak barrels involves Saccharomyces, Brettanomyces, Pediococcus and Lactobacillus over one to three years.
Food pairing
Lambic's acidity makes it a natural partner for fat and salt. Gueuze pairs with moules-frites, oysters, goat cheese, Brussels plattekaas (fresh cheese with radish and onion on bread) and salads with vinaigrette. Kriek works with duck, game terrines, chocolate desserts and cheesecake. Lambic is also used in Belgian cooking, for example rabbit braised in gueuze. Serve it in a straight-sided tumbler, pouring gently from a horizontal basket to avoid disturbing sediment.

Lambic & gueuze: questions and answers
What is the difference between lambic and gueuze?
Lambic is the base beer: spontaneously fermented, aged in oak and usually flat. Gueuze is a blend of one-, two- and three-year-old lambics, bottled so that the young lambic's sugars ferment in the bottle, creating a sparkling, more complex beer.
What is spontaneous fermentation?
In spontaneous fermentation, no yeast is added. Hot wort cools in an open koelschip overnight and is inoculated by wild yeasts and bacteria from the air and the brewery's barrels. Lambic brewers rely on the microflora of the Senne Valley.
What is the difference between kriek and oude kriek?
Oude kriek is traditional: lambic aged on whole sour cherries, with no added sweetener, and refermented in the bottle. Commercial kriek often uses juice or syrup and is sweetened and filtered, giving a sweeter, less sour beer.
