Aroma
Varia conforme o estilo base. Aroma amadeirado baixo a moderado geralmente está presente; algumas variedades podem ter caráter mais forte ou distintivo. Se a madeira é tostada ou carbonizada, pode haver caráter baixo a moderado de baunilha, caramelo, toffee, tostado ou cacau presente. Aromáticos associados a álcool (destilados, vinho) previamente armazenados na madeira devem ser perceptíveis, mas equilibrados.
Aparência
Varia conforme o estilo base. Frequentemente mais escura que a cerveja base inalterada, particularmente se barris carbonizados são usados. Cervejas envelhecidas em barris de vinho ou outros produtos com cores distintivas podem também conferir cor à cerveja final.
Sabor
Varia conforme o estilo base. A madeira geralmente contribui com sabor amadeirado, e possivelmente caráter varietal distintivo. Madeira tostada ou carbonizada pode adicionar baunilha, caramelo, butterscotch, pão tostado, nozes tostadas, café, chocolate ou cacau, dependendo da variedade da madeira e do nível de tostagem ou carbonização. Sabores derivados da madeira e sabores adicionados de álcool devem ser equilibrados, mutuamente sustentadores e perceptíveis, sem sobrepor o estilo base de cerveja ou um ao outro.
Sensação na boca
Varia conforme o estilo base. Taninos da madeira podem aumentar a percepção do corpo, bem como realçar a secura do final; alguma adstringência dos taninos da madeira é permissível. Geralmente exibe calor alcoólico adicional, mas não deve ser quente nem áspero. Características ácidas devem ser baixas a nenhuma, e nunca distrair.
Contexto
Varies with underlying style Additional Notes: These are any traditional or experimental style of lager, ale or hybrid beer aged either a wooden barrel or in contact with wood, and exhibiting acidity derived from exposure to bacteria. These beers are aged in the presence of microflora (either present in the wood or introduced at some time in the brewing process) with the intention of introducing sourness to the beer. These beers are aged with the intention of developing unique attributes imparted by the wood and/or by liquids that had previously been stored in contact with the wood. Wood aging does not necessarily impart wood flavors but does result in distinctive sensory outcomes. Used sherry, rum, whiskey, tequila, port, wine and other barrels are often used, imparting complexity and uniqueness to a beer. A balance of aroma, flavor and mouthfeel results from the marriage of new beer with attributes imparted by the wood or barrel, and with sourness and/or other attributes derived from bacteria. These beers may or may not have Brettanomyces character. For purposes of competition, entries made with fruit are categorized as Fruited Wood-Aged Sour Beer. Entries made with spices are categorized as Herb/Spice Beers. Entries made with combinations of and or fruit(s) and or spices and or other ingredients, and which therefore represent combinations of multiple hybrid beer styles, are categorized as Experimental Beer. Versions made with fruit(s) will exhibit attributes of wood-aging, acidity and those added fruit(s). Competition organizers may choose to create subcategories for Wood-aged sour beers made with fruit or other ingredients. 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 length of time aged, type of wood or barrel, age, char level or previous liquids held by the wood, micro flora present if known, other ingredients or other processing which influence perceived sensory outcomes.
