23-A. American-Style Sour Ale

American Sour Ales are any range of color, and may take on the color of other ingredients. Chill haze, bacteria and yeast-induced haze are allowable at low to medium levels at any temperature. Moderate to intense yet balanced fruity-ester aromas are evident. In darker versions, roasted malt, caramel-like and chocolate-like aromas and flavors are subtly present. Diacetyl and DMS should not be perceived. Hop aroma, flavor and bitterness are evident over a full range from low to high. There is no Brettanomyces character in this style of beer. The evolution of natural acidity develops balanced complexity. The acidity present is usually in the form of lactic, acetic and other organic acids naturally developed with acidified malt in the mash or in fermentation by the use of various microorganisms including certain bacteria and yeasts. Acidic character can be a complex balance of several types of acid and characteristics of age. Residual flavors that come from liquids previously aged in a barrel such as bourbon or sherry should not be present. Wood vessels may be used during the fermentation and aging process, but wood-derived flavors such as vanillin must not be present. Fruited versions will exhibit fruit flavors in harmonious balance with other characters. Body is evident over a wide range from low to high. For purposes of competition entries exhibiting wood-derived characters or characters of liquids previously aged in wood would more appropriately be entered in a Wood-Aged Sour Beer style.
To allow for accurate judging the brewer must provide additional information including the classic style of base beer being elaborated upon, microbes, and/or any other ingredients or processes used. Beer entries not accompanied by this information will be at a disadvantage during judging.
