American Wild Ale - Brett Beer

Name

American Wild Ale

The name American Wild Ale is commonly used 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, or perhaps that they are mixed-fermentation beers. The use of the word American does not mean that the beer has to be based on a Classic Style American beer style, or that the methods are solely practiced in the United States. Base styles in this category do not have to be Classic Styles at all (although they can be); something like, “blond ale, 7%” would be fine, since the underlying style is often lost under the fermentation character.
This category is intended for a wide range of beers that do not fit traditional European sour, wild, or spontaneously-fermented styles. All of the styles in this category are Specialty-Type 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.
The styles in this category are differentiated by the types of yeast and bacteria used – see the preamble to each style for more information. We use the conversational shorthand terms used in the brewing industry: Brett for Brettanomyces, Sacch for Saccharomyces, Lacto for Lactobacillus, and Pedio for Pediococcus. See the Glossary for additional information. The Wild Specialty Beer style is for beers for other styles within this category when Specialty-Type Ingredients are added. Background levels of oak may be used in all styles within this category, but beers aged in other woods with unique flavors or barrels that contained other alcohol products must be entered in the Wild Specialty Beer style.

Guidelines

Impression

Most often drier and fruitier than the base style suggests. Fruity or funky notes range from low to high, depending on the age of the beer and strains of Brett used. May possess a light non-lactic acidity.

Aroma

Variable by base style. Young Brett beers will possess more fruity notes (e.g., tropical fruit, stone fruit, or citrus), but this is variable by the strains of Brett used. Older 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.

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.

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. Always fruitier when young, gaining more funk with age. May not be 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.

Mouth Feel

Variable by base style. Generally has 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, but often less than the base style.

Comments

The base style describes most of the character of these beers, but the addition of Brett ensures a drier, thinner, and often fruitier 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. The Brett character should always meld with the style; these beers should never be a ‘Brett bomb’. While Brett can produce low levels of organic acids, it is not a primary beer souring method.

History

Modern American craft beer interpretations of Belgian wild ales, or experimentations inspired by Belgian wild ales or historical English beers with Brett. So-called 100% Brett beers gained popularity after the year 2000, but this was when S. Trois was thought to be a Brett strain (which it isn’t). Brett used in conjunction with a Sacch fermentation is standard practice now.

Ingredients

Virtually any style of beer (except those already using a Sacch/Brett co-fermentation), then finished with one or more strains of Brett. Alternatively, a mixed fermentation with Sacch and one or more strains of Brett. No Lacto.

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 Style, or provide a description of the ingredients, specs, or desired character. The entrant may specify the strains of Brett used.
