European Sour Ale Lambic

BJCP 23D

BJCP 2015 23D Lambic example
23D - Lambic

Aroma

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.

Appearance

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.

Flavor

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.

Mouth Feel

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

Overall Impression

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.

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. 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.;

Comments

Straight lambics are single-batch, unblended beers. Since they are unblended, the straight lambic is often a true product of the "house character" of a brewery and will be more variable than a gueuze. They are generally served young (6 months) and on tap as cheap, easy-drinking beers without any filling carbonation. Younger versions tend to be one-dimensionally sour since a complex Brett character often takes upwards of a year to develop. An enteric character is often indicative of a lambic that is too young. A noticeable vinegary or cidery character is considered a fault by Belgian brewers. Since the wild yeast and bacteria will ferment ALL sugars, they are typically bottled only when they have completely fermented.

History

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.

Commercial Examples

The only bottled version readily available is Cantillon Grand Cru Bruocsella of whatever single batch vintage the brewer deems worthy to bottle. De Cam sometimes bottles their very old (5 years) lambic. In and around Brussels there are specialty cafes tha

Style Comparison

Generally has a more simple sourness and complexity than a gueuze. Traditionally served uncarbonated from pitchers, while gueuze is bottled and very highly carbonated.
