Fruit Lambics are spontaneously fermented beers from the Lambic region of Belgium that have been aged with whole fruits. The most common examples are Kriek (cherry) and Framboise (raspberry), though other fruits have been used. The fruit additions provide acidity, flavor complexity, and natural color. These beers combine the dry, funky character of base lambic with the tart, fruity qualities of the added fruit.
Fruit additions to beer have ancient roots. The Sumerians added dates to beer, Egypt used oranges, and in Turkey, grapes were allegedly added to beer for King Midas. However, the modern Fruit Lambic tradition specifically developed in Belgium where spontaneously fermented lambics provided the perfect base for fruit aging.
The most iconic Fruit Lambic is Kriek, traditionally made with small, dark, acidic Morello cherries. These cherries are harvested in July and added to fermenting lambic. The beer is then aged on the cherries for a minimum of six weeks, though quality examples often age much longer. The cherry pits, wood, and flesh all contribute to the final character.
Framboise uses raspberries, typically added to aged lambic rather than fermenting lambic. The shorter contact time compared to Kriek reflects the different character of raspberries and their more delicate flavor.
American breweries have adopted the fruit lambic concept using coolships (traditional shallow cooling vessels for spontaneous fermentation) and various local fruits. Portland, Oregon's craft breweries particularly embraced this style, creating unique regional variations.
Historical Belgian producers include Boon, Cantillon, De Cam, Drie Fonteinen, and Hanssels—breweries dedicated to preserving lambic traditions while experimenting with fruit additions.
Color varies dramatically based on fruit used. Kriek ranges from medium to deep red. Framboise appears pink to deep red. Clarity varies from clear to slightly hazy due to fruit particulates. Head is typically low and pink/reddish.
Prominent fruit aroma (cherry, raspberry, or other fruits) dominates. Sour, acidic notes from fermentation. Subtle funky wild yeast and brett character underlying the fruit.
The fruit provides primary flavor alongside sour, acidic character from spontaneous fermentation. Dry, complex, layered profile. No residual sweetness despite fruit additions. The interaction of fruit tannins with wild fermentation creates complexity.
Fruit character dominates: cherry, raspberry, or other fruits depending on variety. Dry, acidic, sour notes from spontaneous fermentation and wild bacteria.
Subtle funky, earthy, vineyard-like characters from wild yeasts (Brettanomyces). Tannins from fruit pits and skins contribute complexity and slight astringency.
Long, dry, sour finish with lingering fruit character. No sweetness. Very refreshing and complex.
Serve at cool cellar temperature (50-55°F) in a wine glass or specialty Belgian glass to showcase aroma and complexity. An aperitif or dessert beer rather than a session beer.
Overall Impression: A complex, fruity, pleasantly sour, wild wheat ale fermented by a variety of Belgian microbiota, and showcasing the fruit contributions blended with the wild character. The type of fruit can sometimes be hard to identify as fermented and aged fruit characteristics can seem different from the more recognizable fresh fruit aromas and flavors.
Aroma: The specified fruit should be the dominant aroma. A low to moderately sour character blends with aromas described as barnyard, earthy, goaty, hay, horsey, and horse blanket (and thus should be recognizable as a lambic). The fruit aroma commonly blends well with the other aromas. An enteric, smoky, cigar-like, or cheesy aroma is unfavorable. No hop aroma.
Appearance: The variety of fruit generally determines the color, although lighter-colored fruit may have little effect on the color. The color intensity may fade with age. Clarity is often good, although some fruit will not drop bright. A thick rocky, mousse-like head, sometimes a shade of fruit, is generally long-lasting (carbonation-dependent). Carbonation is typically high, but must be specified.
Flavor: The specified fruit should be evident. Low to moderately sour flavor, often with an acidic bite in the finish. The classic barnyard characteristics may be low to high. When young, the beer will present its full fruity taste. As it ages, the lambic taste will become dominant at the expense of the fruit character – thus fruit lambics are not intended for long aging. The finish is commonly dry and tart, but a low, complementary sweetness may be present; higher sweetness levels are not traditional but can be included for personal preference (sweetness level must be specified). A mild vanilla and/or oak flavor is occasionally noticeable. An enteric, smoky or cigar-like character is undesirable. Hop bitterness is generally absent; acidity provides the balance. No hop flavor.
Mouthfeel: Light to medium-light body. In spite of the low finishing gravity, the many mouth-filling flavors prevent the beer from tasting like water. Has a low to high tart, puckering quality without being sharply astringent. Some versions have a light warming character. Carbonation can vary from sparkling to nearly still (must be specified).
Comments: Fruit-based lambics are often produced like gueuze by mixing one, two, and three-year old lambic. "Young" lambic contains fermentable sugars while old lambic has the characteristic "wild" taste of the Senne River valley. Fruit is commonly added halfway through aging and the yeast and bacteria will ferment all sugars from the fruit. Fruit may also be added to unblended lambic. The most traditional styles of fruit lambics include kriek (cherries), framboise (raspberries) and druivenlambik (muscat grapes). IBUs are approximate since aged hops are used; Belgians use hops for anti-bacterial properties more than bittering in lambics.
History: Spontaneously fermented wild ales from the area in and around Brussels (the Senne Valley) stem from a farmhouse brewing and blending tradition several centuries old. The number of producers is constantly dwindling and some are untraditionally sweetening their products (post-fermentation) with sugar or sweet fruit to make them more palatable to a wider audience. Fruit was traditionally added to lambic or gueuze, either by the blender or publican, to increase the variety of beers available in local cafes.
Characteristic Ingredients: Unmalted wheat (30-40%), Pilsner malt and aged hops (3 years) are used. The aged hops are used more for preservative effects than bitterness, and makes actual bitterness levels difficult to estimate. Traditional products use 10-30% fruit (25%, if cherry). Fruits traditionally used include tart cherries (with pits), raspberries or Muscat grapes. More recent examples include peaches, apricots or merlot grapes. Tart or acidic fruit is traditionally used as its purpose is not to sweeten the beer but to add a new dimension. Traditionally these beers are spontaneously fermented with naturally occurring yeast and bacteria in predominately oaken barrels. The barrels used are old and have little oak character, so don't expect a fresh or forward oak character – more neutral is typical. Home-brewed and craft-brewed versions are more typically made with pure cultures of yeast commonly including Saccharomyces, Brettanomyces, Pediococcus and Lactobacillus in an attempt to recreate the effects of the dominant microbiota of Brussels and the surrounding countryside of the Senne River valley. Cultures taken from bottles are sometimes used but there is no simple way of knowing what organisms are still viable.
Style Comparison: A lambic with fruit, not just a fruit beer; the wild lambic character must be evident. Entry Instructions: The type of fruit used must be specified. The brewer must declare a carbonation level (low, medium, high) and a sweetness level (low/none, medium, high).

Traditional lambic grain bill: Belgian pale malt (65-75%), unmalted wheat (25-35%), small amounts of roasted malt (1-2%). Aged hops (3+ years) for preservative character without bittering.
Spontaneous fermentation using wild yeasts and bacteria in the Lambic region's air and wooden vessels. Coolships for cooling, open fermentation in wooden barrels.
Traditional Kriek: Small dark Morello cherries, whole with pits, added to fermenting lambic in a 1:1 or 1:2 ratio. Fermentation continues on the fruit.
Framboise: Raspberries added to aged lambic, typically in smaller quantities than Kriek.
Other fruits: Any fruit may theoretically be used, though cherries and raspberries remain traditional.
Kriek: Minimum 6 weeks on fruit, often much longer (months to years). Complex interplay between fruit character and wild fermentation.
Bottle conditioning without filtration or pasteurization maintains live character.
