A fairly sour, often moderately funky wild Belgian wheat beer with sourness taking the place of hop bitterness in the balance. Traditionally spontaneously fermented in the Brussels area and served uncarbonated, the refreshing acidity makes for a very pleasant café drink.
Pale yellow to deep golden in color; age tends to darken the beer. Clarity is hazy to good. Younger versions are often cloudy, while older ones are generally clear. White colored head generally has poor retention.
A decidedly sour aroma is often dominant in young examples, but may become more subdued with age as it blends with aromas described as barnyard, earthy, goaty, hay, horsey, and horse blanket. A mild citrus-fruity aroma is considered favorable. An enteric, smoky, cigar-like, or cheesy aroma is unfavorable. Older versions are commonly fruity with aromas of apples or even honey. No hop aroma.
Young examples are often noticeably lactic-sour, but aging can bring this character more in balance with the malt, wheat and barnyard characteristics. Fruity flavors are simpler in young lambics and more complex in the older examples, where they are reminiscent of apples or other light fruits, rhubarb, or honey. Some citrus flavor (often grapefruit) is occasionally noticeable, and is desirable. The malt and wheat character are typically low with some bready-grainy notes. An enteric, smoky or cigar-like character is undesirable. Hop bitterness is low to none, and generally undetectable; sourness provides the balance. Typically has a dry finish. No hop flavor.
Light to medium-light body. In spite of the low finishing gravity, the many mouth-filling flavors prevent the beer from feeling like water. As a rule of thumb, lambic dries with age, which makes dryness a reasonable indicator of age. Has a medium to high tart, puckering quality without being sharply astringent. Traditional versions are virtually to completely uncarbonated, but bottled examples can pick up moderate carbonation with age.
Spontaneously fermented wild ales from the area in and around Brussels (the Senne Valley) stem from a farmhouse brewing tradition several centuries old. The number of producers is constantly dwindling.
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. Traditionally these beers are spontaneously fermented with naturally occurring yeast and bacteria in predominately oaken barrels. The barrels used are neutral with 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.
Generally has a more simple sourness and complexity than a gueuze. Traditionally served uncarbonated from pitchers, while gueuze is bottled and very highly carbonated.
