The guideline, in detail
Official style attributes, including what may be present and what should be absent.
Hop aroma & flavor
Low to high
Perceived bitterness
Low to high
Body & mouthfeel
Low to high
Clarity
Chill haze, bacteria and yeast-induced haze is allowable at low to medium levels at any temperature.
Color
Any color is acceptable. Beer color may be influenced by the color of added fruits or other ingredients.
Fermentation characteristics
Medium to high fruity esters are present. Acidity resulting from fermentation with Brettanomyces and bacteria results in a complex flavor profile. Brettanomyces character should be present and expressed as any of horsey, goaty, leathery, phenolic, fruity, or acidic aroma and flavor attributes. Cultured yeast may be used in the fermentation. Bacteria should be incorporated and in evidence. Bacteria will contribute acidity which may or may not dominate the flavor profile. Diacetyl and DMS should not be present.
Additional guideline notes & competition context
Fruited versions will exhibit fruit flavors in balance with other elements. Wood vessels may be used for fermentation and aging; such beers may or may not exhibit attributes typical of wood-aging such as vanillin or of liquids previously aged in a barrel (bourbon, sherry, etc.). When using these guidelines as the basis for evaluating entries at competitions, brewers may be asked to provide supplemental information about entries in this category to allow for accurate evaluation of diverse entries. Such information might include the underlying beer style upon which the entry is based, or other information unique to the entry such as type of Brett(s) and other culture(s) used, fruit(s), type of wood used (if any), or other ingredients or processing which influence perceived sensory outcomes.
