Beer Centric: Belgium Lambic

Lambic beer occupies a fascinating corner of the brewing world, a place where tradition, geography, and a bit of wild fermentation come together in every glass. Unlike most modern beers, which rely on carefully selected cultivated yeasts, Lambics are born from spontaneous fermentation. Brewers in the Pajottenland region and the Senne Valley near Brussels expose their wort to the open air, allowing native wild yeasts and bacteria -- most notably Brettanomyces bruxellensis and Brettanomyces lambicus -- to take hold. The beer is then transferred to oak barrels (often previously used for port or sherry) for aging, where it matures for one to several years. This ancient method, dating back centuries, produces beers with unmistakable character: tart, funky, earthy, and extremely textured. The result is a style deeply tied to its environment as Lambic beer simply cannot be authentically replicated outside this small Belgian region because the local microflora are part of its identity.

Over time, Lambic brewing evolved into several substyles, including Gueuze, Kriek, and Framboise, each created by blending or fermenting the base beer with fruit. Gueuze is created by blending younger and older batches to create a highly carbonated, complex beer often compared to Champagne. Kriek is a Lambic augmented with cherries, whereas Framboise is a Lambic augmented with raspberries.

Among the most famous examples of the latter is Lindemans Framboise, a raspberry Lambic that showcases how fruit can soften and brighten the wild complexity of the base beer. Lindemans begins with a traditional Lambic foundation, then adds whole raspberries that subsequently spark a secondary fermentation. The fruit infuses the beer with a vivid ruby color, a fragrant berry aroma, and a balance of sweetness and tartness that makes it approachable even for those new to sour beers. Many thanks to the two centuries of brewing from the six generations of the Lindeman family.

What makes Lambic so compelling is the way it bridges past and present. It’s a living reminder of pre-industrial brewing, yet it continues to evolve through the creativity of producers like Lindemans. Whether you’re savoring the rustic funk of an unblended Lambic or the fruit-forward charm of a Framboise, you’re tasting a beer shaped by its land, its history, and the invisible wild yeasts that have floated through Belgian air for centuries. Lambic isn’t just a beverage—it’s a cultural artifact, a sensory time capsule, and a testament to the beauty of letting nature take the lead.

Belgium Beer: Gueuze Lambics with the Gueuze Tilquin à l’ancienne

Belgium has provided the world with a plethora of historic beer styles most likely because the industry wasn't hampered by government degrees like the German reinheitsgebot. Their brewing history, starting with Trappist Monks, has supplied us with Dubbel, Tripel, Quad, Saison, Witbier, Flanders Red, Belgian Dark Strong Ale, Belgian Blond Ale, Belgian Pale Ale, Belgian Golden Strong Ale, Oud Bruin, and Lambic beer styles. American consumers most likely think that the last style must contain fruit, however, that is not necessarily so. In fact, Lambics can be further segmented into framboise (raspberries), kriek (cherries), straight lambics, and gueuze.

Gueuze beers are created when blenderies purchase freshly brewed worts from different producers, combine them into oak barrels, and allow them to naturally ferment. Then 1, 2 and 3 years old lambics are blended together and because the young lambics are not fully fermented, the blended beer contains fermentable sugars, which allow a second fermentation to occur in the bottle. The end result is the "Champagne of Belgium" which tends towards a yeasty slightly sour and barnyard profile.

One of the most prolific producers of this style is Gueuzerie Tilquin -- the only gueuze blendery in Wallonia. Their flagship beer is the Gueuze Tilquin à l’ancienne (7% abv) which starts as wort brewed by Boon, Lindemans, Girardin and Cantillon. The blended worts are then fermented and matured in oak barrels at the blendery. After blending the different years, the lambics are then allowed to re-ferment for six months in the bottle.

One local Northern Virginia restaurant, Rustico, carries this beer in different size bottles from 37.5cl ($45) to a magnum ($90).  The profile is very bready - almost grainy with a slightly sour core that stays through the tail. This finish also exhibits a dry tannic bitterness that should be alluring to wine drinkers.  Starting Friday, December 13 Rustico is hosting their annual 12 Days of Christmas Beers where all bottles are 50% off. Since Gueuze beers are priced on the high side, this is a great opportunity to sample these delicious beers. Cheers.
