This category contains the traditional sour beer styles of Europe that are still produced, many (but not all) with a wheat component. Most have low bitterness, with the sourness of the beer providing the balance that hop bitterness would otherwise contribute. Some are sweetened or flavored, whether at the brewery or upon consumption.
23A. Berliner Weisse
Overall Impression
A very pale, refreshing, low-alcohol German wheat beer with a clean lactic sourness and a very high carbonation level. A light bread dough malt flavor supports the sourness, which shouldn’t seem artificial. A gentle fruitiness is found in the best examples.
Appearance
Straw in color, can be very pale. Clarity ranges from clear to somewhat hazy. Large, dense, white head with poor retention. Highly effervescent.
Aroma
A moderate to moderately-high sharply sour character is dominant. Can have up to a moderately fruitiness, often lemon, tart apple, peach, or apricot, and a light floral note. No hop aroma. The wheat may be perceived as raw bread dough in fresher versions; combined with the acidity, may suggest sourdough bread.
Flavor
Clean lactic sourness dominates and can be quite strong. A complementary doughy, bready, or grainy wheat flavor is generally noticeable. Hop bitterness is undetectable; sourness provides the balance rather than hops. Never vinegary. Bright yet restrained fruitiness may be detected as apricot-peach, citrus-lemon, or tart apple. Very dry finish. Balance dominated by sourness, but some malt flavor should be present. No hop flavor. No THP.
Mouthfeel
Light body, but never thin. Very high carbonation. No sensation of alcohol. Crisp acidity.
History
A regional specialty of Berlin. Referred to by Napoleon’s troops in 1809 as “the Champagne of the North” due to its lively and elegant character. At one point, it was smoked and there used to be Märzen-strength (14 °P) version. Increasingly rare in Germany, but now produced in several other countries.
Characteristic Ingredients
: Pilsner malt. Usually wheat malt, often at least half the grist. A symbiotic co-fermentation with top-fermenting yeast and LAB provides the sharp sourness, which may be enhanced by blending of beers of different ages during fermentation and by cool aging. Decoction mashing with mash hopping is traditional. German brewing scientists believe that Brett is essential to get the correct, fruity-floral flavor profile.
Style Comparison
Compared to Lambic, has a clean lactic sourness with restrained to below sensory threshold Brett. Also lower in alcohol content. Compared to Straight Sour Beer and Catharina Sour, is lower gravity and may contain Brett.

23B. Flanders Red Ale
Overall Impression
A sour and fruity oak-aged reddish-brown Belgian-style ale with supportive toasty malt flavors and fruit complexity. The dry, tannic finish supports the suggestion of a vintage red wine.
Appearance
Deep red, burgundy to reddish-brown in color. Good clarity. White to very pale tan head. Average to good head retention.
Aroma
Complex fruity-sour profile with supporting malt. Fruitiness is high, and reminiscent of black cherries, oranges, plums, red currants, or fruit leather. Low to medium-low vanilla, chocolate, or peppery phenol can be present for complexity. The sour aroma ranges from moderate to high. A dominant vinegary character is inappropriate, although low to moderate levels of acetic acid are acceptable if balanced with the malt. No hop aroma.
Flavor
Moderate to moderately-high malty flavors often have a soft toasty-rich quality. Intense fruit flavors, same descriptors as aroma. Complex, moderate to high sourness, accentuated by the esters; should not be a simple lactic sourness. A dominant vinegary character is inappropriate, although low to moderate acetic acid is acceptable if balanced with the malt. Generally as the sour character increases, the malt character fades to more of a background flavor (and vice versa). Low to medium-low vanilla, chocolate, or peppery phenols optional. No hop flavor. Restrained bitterness; balanced to the malt side. Acids and tannins can enhance the perception of bitterness, and provide balance and structure. Some versions are sweetened, or blended to be sweet; allow for a wide range of sweetness levels, which can soften the acidic bite and acetic perception.
Mouthfeel
Medium body, often enhanced by tannins. Low to medium carbonation. Low to medium astringency, often with a prickly acidity. Deceivingly light and crisp on the palate although a somewhat sweet finish is not uncommon.
Comments
The “wine-like” observation should not be taken too literally; it may suggest a high-acid French Burgundy to some, but it is clearly not identical. Produced by long aging (up to two years) in large wooden vats (foeders), blending of young and well-aged beer, and variable amounts of sweetening of the final product. A wide range of products are possible depending on the actual blend and whether any sweetening takes place. Acetic flavors may be noted, but not all acidity in this beer is from acetic acid; vinegar is over six times greater in total acidity than this style. Fruited versions should be entered as a 29A Fruit Beer.
History
An indigenous beer of West Flanders, typified by the products of the Rodenbach brewery, established in 1821. Aging in wooden vats and blending of old and young beers borrowed from the English tradition. Belgian brewers consider Flanders Red and Oud Bruin to be of the same style family, but the distinction was first made when Michael Jackson first defined beer styles, since the flavor profiles are distinctly different. Many modern examples are influenced by the popularity of Rodenbach Grand Cru.
Characteristic Ingredients
Vienna or Munich malts, a variety of caramel malts, maize. Low alpha acid continental hops. Sacch, Lacto, and Brett. Aged in oak. Sometimes blended and sweetened (natural or artificial).
Style Comparison
Less malty-rich than an Oud Bruin, often with more of a fruity-tart and acetic profile.

23C. Oud Bruin
Overall Impression
A malty, fruity, aged, somewhat sour Belgian-style brown ale with a caramel-chocolate malt flavor, and often substantial alcohol.
Appearance
Dark reddish-brown to brown in color. Good clarity. Average to good head retention. Ivory to light tan head color.
Aroma
Richly malty with fruity esters and an aged sourness. Medium to medium-high esters commonly reminiscent of raisins, plums, figs, dates, oranges, black cherries, or prunes. Medium-low to medium-high malt with caramel, toffee, treacle, or chocolate character. Low spicy-peppery phenols optional. A low sour aroma may be present, and can modestly increase with age but should not grow to a strongly acetic, vinegary character. Hop aroma absent. Aged examples can show a lightly nutty, sherry-like oxidation character.
Flavor
Malty with fruity complexity and typically some dark caramel or burnt sugar flavor. Medium-low to medium-high malt, same descriptors as aroma. Medium to medium-high fruitiness, same descriptors as aroma. Low spicy-peppery phenols optional. A slight sourness often becomes more pronounced in well-aged examples, along with some sherry-like character, producing a “sweet-and-sour” profile and aftertaste. The sourness should not grow to a strongly acetic, vinegary character. Hop flavor absent. Restrained hop bitterness. Balance is malty, but with fruitiness and sourness present. Blending and sweetening may produce a range of finishes, and balances.
Mouthfeel
Medium to medium-full body. Low to moderate carbonation. No astringency. Stronger versions can be noticeably warming.
Comments
Long aging and blending of young and aged beer may occur, adding smoothness and complexity and balancing any harsh, sour character. Traditionally, this style was designed to lay down so examples with a moderate aged character are considered superior to younger examples. Fruited versions should be entered as a 29A Fruit Beer.
History
An indigenous beer of East Flanders, typified by the products of the Liefman brewery with roots back to the 1600s. Belgian brewers consider Flanders Red and Oud Bruin to be of the same style family, but the distinction was first made when Michael Jackson first defined beer styles, since the flavor profiles are distinctly different. Many modern examples are influenced by the popularity of Liefmans Goudenband. Unrelated to the dark, sweet Dutch lager of the same name.
Characteristic Ingredients
Pils malt, dark crystal malts, maize, small amounts of color malt. Low alpha acid continental hops. Sacch and Lacto. Aged. Water with carbonates and magnesium typical of its home region.
Style Comparison
A deeper malt character with more caramel, toffee, and chocolate flavors and darker color distinguishes these beers from Flanders Red Ale. The Oud Bruin is less acetic and maltier than a Flanders Red, and the fruity flavors are more malt-oriented. In modern times, Oud Bruin also tends to be higher in alcohol than is typically seen in Flanders Red Ales. Differs from Lambic in that they are not spontaneously fermented, and don’t contain wheat.

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 served uncarbonated as a café drink.
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.
Aroma
Young versions can be quite sour and fruity, but can develop barnyard, earthy, goaty, hay, horsey, or horse blanket funkiness with age. The fruit character can take on a light citrus fruit, citrus rind, pome fruit, or rhubarb quality, getting more complex with age. Malt can have a light bready, grainy, honey, or wheat-like quality, if noticeable. Should not have enteric, smoky, cigar-like, or cheesy faults. No hops.
Flavor
Young versions often have a strong lactic sourness with fruity flavors (same descriptors as aroma), while aged versions are more balanced and complex. Funky notes can develop over time, same descriptors as aroma. Low bready, grainy malt. Bitterness generally below sensory threshold; sourness provides the balance. No hop flavor. Dry finish, increasing with age. Should not have enteric, smoky, cigar-like, or cheesy faults.
Mouthfeel
Light to medium-light body; should not be watery. 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
A single-batch, unblended beer, reflecting the house character of the brewery. Generally served young (6 months) from the cask. Younger versions tend to be one-dimensionally sour since a complex Brett character takes a year or more to develop. A noticeable vinegary or cidery character is considered a fault by Belgian brewers. Typically bottled only when completely fermented. Lambic sweetened with raw sugar at service time is known as Faro.
History
Spontaneously-fermented ‘wild’ ales from the area in and around Brussels (also known as the Senne Valley and the Pajottenland) stem from a farmhouse brewing tradition several centuries old.
Characteristic Ingredients
Pilsner malt, unmalted wheat. Aged hops (3+ years) used more as a preservative than for bitterness. Spontaneously fermented with naturally occurring yeast and bacteria in well-used, neutral oak barrels.
Style Comparison
Often has a simpler sourness and less complexity than a Gueuze, but more variability from batch to batch. Traditionally served uncarbonated from pitchers, while Gueuze is bottled and very highly carbonated.

23E. Gueuze
Overall Impression
A very refreshing, highly carbonated, pleasantly sour but balanced wild Belgian wheat beer. The wild beer character can be complex and varied, combining sour, funky, and fruity flavors.
Appearance
Golden color, with excellent clarity and a thick, rocky, mousse-like, white head that seems to last forever. Effervescent.
Aroma
Moderately sour with complex but balanced funkiness accented by fruity notes. The funkiness can be moderate to strong, and can be described as barnyard, leather, earthy, goaty, hay, horsey, or horse blanket. Fruitiness is light to moderate, with a citrus fruit, citrus rind, pome fruit, or rhubarb quality. Malt is supportive, and can be lightly bready, grainy, honey, or wheat-like, if noticeable. Should not have enteric, smoky, cigar-like, or cheesy faults. No hops. Light oak acceptable. Complexity of aroma is valued more than intensity, but a balanced sour presentation is desirable.
Flavor
Sour and funky on the palate, with a similar character as the aroma (same descriptors and intensities apply for funk and fruit). Low bready, grainy malt. Bitterness low to none; sourness provides most of the balance. No hop flavor. Crisp, dry finish, with a tart and funky aftertaste. Light oak, vanilla, and honey are acceptable. Should not have enteric, smoky, cigar-like, or cheesy faults. The beer should not be one dimensionally sour; a balanced, moderately sour presentation is classic, with the funky and fruity notes providing complexity. May be aged.
Mouthfeel
Light to medium-light body; should not be watery. Has a low to high tart, puckering quality without being sharply astringent. Some versions have a very light warming character. Highly carbonated.
Comments
Blending young and aged lambic creates a more complex product, and often reflects the personal taste of the blender. 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 texture. Lambic is served uncarbonated, while Gueuze is served sparkling. Products marked oude or vieille (“old”) are considered most traditional.
History
Same basic history as Lambic, but involves blending, which may be performed outside the brewery. Some of the best examples are produced by blenders, who ferment, age, blend, and package the final product. Some modern producers are sweetening their products post-fermentation to make them more palatable to a wider audience. These guidelines describe the traditional dry product.
Characteristic Ingredients
Same as Lambic, except that one-, two-, and three-year old Lambics are blended, then cellared.
Style Comparison
More complex and carbonated than a Lambic. The sourness isn’t necessarily stronger, but it tends to have more of a well-developed wild character.

23F. Fruit Lambic
Overall Impression
A complex, refreshing, pleasantly sour Belgian wheat beer blending a complementary fermented fruit character with a sour, funky Gueuze.
Appearance
Like Gueuze, but modified by the color of the fruit used, fading in intensity with age. Clarity is often good, although some fruit will not drop bright. If highly carbonated in the traditional manner, will have a thick rocky, generally long-lasting, mousse-like head, sometimes with a hue reflecting the added fruit.
Aroma
The specified fruit should be the dominant aroma, blending well with similar aromatics as Gueuze (same description applies, but with the addition of a fermented fruit character).
Flavor
Combines the flavor profile of a Gueuze (same description applies) with noticeable flavor contributions from the added fruit. Traditional versions are dry and tart, with an added fermented fruit flavor. Modern versions may have a variable sweetness, which can offset the acidity. Fruit flavors also fade with age, and lose their vibrancy, so can be low to high in intensity.
Mouthfeel
Light to medium-light body; should not be watery. 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.
Comments
Produced like Gueuze, with the fruit commonly added halfway through aging, so the yeast and bacteria can ferment all sugars from the fruit; or less commonly by adding fruit to a Lambic. The variety of fruit can sometimes be hard to identify since fermented and aged fruit is often perceived differently than the more recognizable fresh fruit. Fruit can bring acidity and tannins, in addition to flavor and aroma; understanding the fermented character of added fruit helps with judging the style.
History
Same basic history as Gueuze, including the recent sweetening trend but with fruit in addition to sugar. Fruit was traditionally added by the blender or publican to increase the variety of beers available in local cafés.
Characteristic Ingredients
Same base as Gueuze. Fruit added to barrels during fermentation and blending. Traditional fruit include tart cherries, raspberries; modern fruit include peaches, apricots, grapes, and others. May use natural or artificial sweeteners.
Style Comparison
A Gueuze with fruit, not just a sour Fruit Beer; the wild 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).

23G. Gose
Overall Impression
A tart, lightly-bittered historical central European wheat beer with a distinctive but restrained salt and coriander character. Very refreshing, with a dry finish, high carbonation, and bright flavors.
Appearance
Unfiltered, with a moderate to full haze. Moderate to tall white head with tight bubbles and good retention. Effervescent. Yellow color.
Aroma
Light to moderately fruity aroma of pome fruit. Light sourness, slightly sharp. Noticeable coriander, which can have an aromatic lemony quality, and an intensity up to moderate. Light bready, doughy, yeasty character like uncooked sourdough bread. The acidity and coriander can give a bright, lively impression. The salt may be perceived as a very light, clean sea breeze character or just a general freshness, if noticeable at all.
Flavor
Noticeable sourness, medium-low to medium-high. Moderate bready or doughy malt flavor. Light to moderate fruity character of pome fruit, stone fruit, or lemons. Light to moderate salt character, up to the threshold of taste; the salt should be noticeable (particularly in the initial taste) but not taste overtly salty. Very low bitterness. No hop flavor. Dry, fully-attenuated finish, with acidity not hops balancing the malt. Acidity can be more noticeable in the finish, and enhance the refreshing quality of the beer. The acidity should be balanced, not forward (although historical versions could be very sour). No THP.
Mouthfeel
High to very high carbonation. Effervescent. Medium-light to medium-full body. Salt may give a slightly tingly, mouthwatering quality and a rounder, thicker mouthfeel. Yeast and wheat can also add a little body, but shouldn’t feel heavy due to the thinning effects of acidity.
Comments
Historical versions may have been more sour than modern examples due to spontaneous fermentation, and may be blended with syrups as is done with Berliner Weisse, or with caraway liqueur. Modern examples are inoculated with Lacto, and are more balanced and generally don’t need sweetening. Pronounced GOH-zeh.
History
Minor style associated with Leipzig but originating in the Middle Ages in the town of Goslar on the Gose River. Documented to have been in Leipzig by 1740. Leipzig was said to have 80 Gose houses in 1900. Production declined significantly after WWII, and ceased entirely in 1966. Modern production was revived in the 1980s in Germany, but the beer was not widely available. Became popular outside of Germany recently as a revival style, and is often used as a base style for fruited sour beers and other Specialty-Type beers.
Characteristic Ingredients
Pilsner and wheat malt, restrained use of salt and coriander seed, Lacto. The coriander should have a fresh, citrusy (lemon or bitter orange), bright note, and not be vegetal, celery-like, or ham-like. The salt should have a sea salt or fresh salt character, not a metallic, iodine note.
Style Comparison
Perceived acidity is not as intense as Berliner Weisse or Gueuze. Restrained use of salt, coriander, and Lacto – should not taste overtly salty. Coriander aroma can be similar to a Witbier. Haziness similar to a Weissbier.

Comments
Any Brett character is restrained, and is typically expressed as fruity and floral notes, not funky. Aged examples can show a cider, honey, hay, or gentle wildflower character, and sometimes increased acidity.
In Germany, it is classified as a Schankbier denoting a small beer of starting gravity in the range 7-8 °P. Fruited or Spiced versions should be entered as 29A Fruit Beer, as 30A Spice, Herb, or Vegetable Beer, or as 29B Fruit and Spice Beer.
