23F – Fruit Lambic

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).

23E – Gueuze

Overall Impression: A complex, pleasantly sour but balanced wild Belgian wheat beer that is highly carbonated and very refreshing. The spontaneous fermentation character can provide a very interesting complexity, with a wide range of wild barnyard, horse blanket, or leather characteristics intermingling with citrusy-fruity flavors and acidity.

Aroma: A moderately sour aroma blends with aromas described as barnyard, leather, earthy, goaty, hay, horsey, and horse blanket. While some may be more dominantly sour, balance is the key and denotes a better gueuze. Commonly fruity with aromas of citrus fruits (often grapefruit), apples or other light fruits, rhubarb, or honey. A very mild oak aroma is considered favorable. An enteric, smoky, cigar-like, or cheesy aroma is unfavorable. No hop aroma.

Appearance: Golden color, with excellent clarity and a thick, rocky, mousse-like, white head that seems to last forever. Always effervescent.

Flavor: A moderately sour character is classically in balance with the malt, wheat and barnyard characteristics. A low, complementary sweetness may be present but higher levels are not traditional. While some may be more dominantly sour, balance is the key and denotes a better gueuze. A varied fruit flavor is common, and can have a honey-like character. A mild vanilla and/or oak flavor is occasionally noticeable. The malt is generally low and bready-grainy. An enteric, smoky or cigar-like character is undesirable. Hop bitterness is generally absent but a very low hop bitterness may occasionally be perceived; sourness provides most of the balance. Crisp, dry, and tart finish. 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 feeling like water. Has a low to high tart, puckering quality without being sharply astringent. Some versions have a light warming character. Highly carbonated.

Comments: Gueuze is traditionally produced 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. A noticeable vinegary or cidery character is considered a fault by Belgian brewers. A good gueuze is not the most pungent, but possesses a full and tantalizing bouquet, a sharp aroma, and a soft, velvety flavor. Lambic is served uncarbonated, while gueuze is served effervescent. Products marked oude or ville are considered most traditional.

23D – Lambic

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.

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.

Mouthfeel: 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.

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.

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. 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.

Cultures taken from bottles are sometimes used but there is no simple way of knowing what organisms are still viable.

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.

Vital Statistics:

OG:  1.040 – 1.054

IBUs:  0 – 10

FG:  1.001 – 1.010

SRM:  3 – 7

ABV:  5.0 – 6.5%

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 that often have draught lambics from traditional brewers or blenders such as Boon, De Cam, Cantillon, Drie Fonteinen, Lindemans, Timmermans and Girardin.
