28. American Wild Ale

The name American Wild Ale is in common use by craft brewers and homebrewers. However, the word Wild does not imply that these beers are necessarily spontaneously-fermented; rather, it indicates that they are influenced by microbes other than traditional brewer’s yeasts. This category is intended for a wide range of beers that do not fit traditional European sour or wild styles. All of the styles in this category are essentially specialty beers where many creative interpretations are possible, and the styles are defined only by the use of specific fermentation profiles and ingredients. As specialty styles, the mandatory description provided by the entrant is of the utmost importance to the judge.

Throughout this category, Brett is used as an abbreviation for Brettanomyces. This is the term most craft brewers and homebrewers will use in conversation, if not in formal communications.

28A. Brett Beer

Overall Impression

Most often drier and fruitier than the base style suggests. Funky notes range from low to high, depending on the age of the beer and strain(s) of Brett used. Funkiness is generally restrained in younger 100% Brett examples, but tends to increase with age. May possess a light acidity, although this does not come from Brett.

Appearance

Variable by base style. Clarity can be variable, and depends on the base style and ingredients used. Some haze is not necessarily a fault.

Aroma

Variable by base style. Young Brett-fermented beers will possess more fruity notes (e.g., tropical fruit, stone fruit, or citrus), but this is variable by the strain(s) of Brett used. For 100% Brett beers heavily hopped with American hop varieties, the fermentation-derived flavors are often difficult to tease from the hop aromatics. Older 100% Brett beers may start to develop a little funk (e.g., barnyard, wet hay, or slightly earthy or smoky notes), but this character should not dominate. If the beer is fermented with a brewer’s yeast in addition to Brett, some of the character of the primary yeast may remain. A faint sourness is acceptable but should not be a prominent character.

Flavor

Variable by base style. Brett character may range from minimal to aggressive. Can be quite fruity (e.g., tropical fruit, berry, stone fruit, citrus), or have some smoky, earthy, or barnyard character. Should not be unpleasantly funky, such as Band-Aid, fetid, nail polish remover, cheese, etc. Light sourness is acceptable with the beer being lightly tart, but should not be truly sour. Always fruitier when young, gaining more funk with age. May not be acetic or lactic. Malt flavors are often less pronounced than in the base style, leaving a beer most often dry and crisp due to high attenuation by the Brett.

Mouthfeel

Variable by base style. Generally a light body, lighter than what might be expected from the base style but an overly thin body is a fault. Generally moderate to high carbonation. Head retention is variable.

Comments

The base style describes most of the character of these beers, but the addition of Brett ensures a drier, thinner, and funkier product. Younger versions are brighter and fruitier, while older ones possess more depth of funk and may lose more of the base style character. Wood-aged versions should be entered in the Wild Specialty Beer style. The Brett character should always meld with the style; these beers should never be a ‘Brett bomb’. Note that Brett does not produce lactic acid.

History

Modern American craft beer interpretations of Belgian wild ales, or experimentations inspired by Belgian wild ales or historical English beers with Brett. 100% Brett beers gained popularity after the year 2000; Port Brewing Mo Betta Bretta was one of the first celebrated examples.

Characteristic Ingredients

Virtually any style of beer, fermented in any manner, then finished with one or more strains of Brett. Alternatively, a beer made with Brett as the sole fermentation strain.

Style Comparison

Compared to the same beer style without Brett, a Brett Beer will be drier, more highly attenuated, fruitier, lighter in body, and slightly funkier as it ages. Less sourness and depth than Belgian ‘wild’ ales.

Entry Instructions

The entrant must specify either a base beer style (Classic Style, or a generic style family) or provide a description of the ingredients/specs/desired character. The entrant must specify if a 100% Brett fermentation was conducted. The entrant may specify the strain(s) of Brettanomyces used.

Vital Statistics

Variable by base style.

Commercial Examples

Boulevard Saison Brett, Hill Farmstead Arthur, Logsdon Seizoen Bretta, Russian River Sanctification, The Bruery Saison Rue, Victory Helios.

28B. Mixed-Fermentation Sour Beer

Overall Impression

A sour and/or funky version of a base style of beer.

Appearance

Variable by base style. Clarity can be variable; some haze is not a fault. Head retention can be poor due to high levels of acid or anti-foam properties of some lactobacillus strains.

Aroma

Variable by base style. The contribution of non-Saccharomyces microbes should be noticeable to strong, and often contribute a sour and/or funky, wild note. The best examples will display a range of aromatics, rather than a single dominant character. The aroma should be inviting, not harsh or unpleasant.

Flavor

Variable by base style. Look for an agreeable balance between the base beer and the fermentation character. A range of results is possible from fairly high acidity/funk to a subtle, pleasant, harmonious beer. The best examples are pleasurable to drink with the esters and phenols complementing the malt and/or hops. The wild character can be prominent, but does not need to be dominating in a style with an otherwise strong malt/hop profile. Acidity should be firm yet enjoyable, but should not be biting or vinegary; prominent or objectionable/offensive acetic acid is a fault. Bitterness tends to be low, especially as sourness increases.

Mouthfeel

Variable by base style. Generally a light body, almost always lighter than what might be expected from the base style. Generally moderate to high carbonation, although often lower in higher alcohol examples.

Comments

These beers may be aged in wood, but any wood character should not be a primary or dominant flavor. Sour beers are typically not bitter as these flavors clash. The base beer style becomes less relevant because the various yeast and bacteria tend to dominate the profile. Inappropriate characteristics include diacetyl, solvent, ropy/viscous texture, and heavy oxidation.

History

Modern American craft beer interpretations of Belgian sour ales, or experimentations inspired by Belgian sour ales.

Characteristic Ingredients

Virtually any style of beer. Usually fermented by Lactobacillus and/or Pediococcus, often in conjunction with Saccharomyces and/or Brettanomyces. Can also be a blend of styles. Wood or barrel aging is very common, but not required.

Style Comparison

A sour and/or funky version of a base style.

Entry Instructions

The entrant must specify a description of the beer, identifying the yeast/bacteria used and either a base style or the ingredients/specs/target character of the beer.

28C. Wild Specialty Beer

Overall Impression

A sour and/or funky version of a fruit, herb, or spice beer, or a wild beer aged in wood. If wood-aged, the wood should not be the primary or dominant character.

Appearance

Variable by base style, generally showing a color, tint, or hue from any fruit (if used) in both the beer and the head. Clarity can be variable; some haze is not a fault. Head retention is often poor.

Aroma

Variable by base style. Should show the fruit, sour and/or funk of a wild fermentation, as well as the characteristics of the special ingredients used. The best examples will blend the aromatics from the fermentation with the special ingredients, creating an aroma that may be difficult to attribute precisely.

Flavor

Variable by base style. Should show the fruit, sour and/or funk of a wild fermentation, as well as the characteristics of the special ingredients used. Any fruit sweetness is generally gone, so only the esters typically remain from the fruit. The sour character from the fruit and wild fermentation could be prominent, but should not be overwhelming. The acidity and tannin from any fruit can both enhance the dryness of the beer, so care must be taken with the balance. The acidity should enhance the perception of the fruit flavor, not detract from it. Wood notes, if present, add flavor but should be balanced.

Mouthfeel

Variable by base style. Generally a light body, lighter than what might be expected from the base style. Generally moderate to high carbonation; carbonation should balance the base style if one is declared. The presence of tannin from some fruit or wood can provide a slight astringency, enhance the body, or make the beer seem drier than it is.

Comments

A wild beer featuring fruit, herbs, spices, or wood based on a style other than lambic. Could be another Classic Style (normally sour or not), or something more generic. These beers may be aged in wood, but any wood character should not be a primary or dominant flavor.

History

Modern American craft beer interpretations of Belgian wild ales, or experimentations inspired by Belgian wild ales.

Characteristic Ingredients

Virtually any style of beer. Any combination of Saccharomyces, Brettanomyces, Lactobacillus, Pediococcus, or other similar fermenters. Can also be a blend of styles. While cherries, raspberries, and peaches are most common, other fruits can be used as well. Vegetables with fruit-like characteristics (chile, rhubarb, pumpkin, etc.) may also be used. Wood or barrel aging is very common, but not required.

Style Comparison

Like a fruit, herb, spice, or wood beer, but sour and/or funky.

Entry Instructions

Entrant must specify the type of fruit, spice, herb, or wood used. Entrant must specify a description of the beer, identifying the yeast/bacteria used and either a base style or the ingredients/specs/target character of the beer. A general description of the special nature of the beer can cover all the required items.
