NORTH AMERICAN Origin Style Ales

Source: 2023 Brewers Association Beer Style Guidelines

The Brewers Association’s beer style guidelines reflect, as much as possible, historical significance, authenticity, or a high profile in the current commercial beer market. Often, the historical significance is not clear, or a new beer type in a current market may represent only a passing fad and is quickly forgotten. For these reasons, the addition of a style or the modification of an existing one is not undertaken lightly and is the product of research, consultation, and consideration of market actualities, and may take place over several years.

Since 1979 the Brewers Association has provided beer style descriptions as a reference for brewers and beer competition organizers. Much of the early work was based on the assistance and contributions of beer journalist Michael Jackson; more recently these guidelines were greatly expanded, compiled, and edited by Charlie Papazian. The task of creating a realistic set of guidelines is always complex. The beer style guidelines developed by the Brewers Association use sources from the commercial brewing industry, beer analyses, and consultations with beer industry experts and knowledgeable beer enthusiasts as resources for information

Beers exceeding 5.0% abv are not considered Session India Pale Ales. Beers under 5.0% abv (4.0% abw) which meet the criteria for another classic or traditional style category are not considered Session India Pale Ales. An India Pale Ale made to alcohol content below 0.5% abv (0.4% abw) is categorized as a Non-Alcohol Malt Beverage.

Perceived Hop Aroma & Flavor: Medium-high to very high hop aroma and flavor are present, exhibiting a very wide range of attributes, especially fruity, tropical, juicy, and many others.

Body: Medium-low to medium-high. Perceived silky or full mouthfeel may contribute to overall flavor profile.
Additional notes: Grist may include oats, wheat, or other adjuncts to promote haziness. The term ‘juicy’ is frequently used to describe taste and aroma attributes often present in these beers which result from late, often very large, additions of hops.

Likewise the term ‘hazy’ is frequently used to describe the appearance of many examples of these beers. However, some versions may exhibit very low cloudiness. These beers can exhibit astringency and heat (sometimes referred to as ‘hop burn’) as a result of very high hop usage rates and excessive contact time in beer, which can detract from balance and drinkability when present above low levels.

A juicy character is not required, however. Other hop-derived attributes such as citrus, pine, spice, floral or others may be present with or without the presence of juicy attributes. Likewise the term ‘hazy’ is frequently used to describe the appearance of many examples of these beers. However, some versions may exhibit very low cloudiness.

Additional notes: American-Belgo-Style Ales are either 1) non-Belgian beer types portraying the unique characters imparted by yeasts typically used in big, fruity Belgian-style ales, or 2) defined Belgian-style beers displaying the hallmark attributes typical of American variety hops.

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 kettle or post wort fermentation and is produced by various microorganisms including certain bacteria and yeasts. Acidic character can be a complex balance of several types of acid and attributes of age. Wood vessels may be used during the fermentation and aging process, but wood-derived flavors such as vanillin should not be present. There should be no residual flavors from liquids previously aged in a barrel such as bourbon or sherry.
Body: Low to high
Additional notes: Beers exhibiting wood-derived characters or characters of liquids previously aged in wood are categorized as Wood-Aged Sour Beer. Fruited versions are categorized elsewhere.

Color: Can range from pale to black depending on underlying beer style and is often influenced by the color of added fruit
Clarity: Chill haze, bacteria, and yeast-induced haze is acceptable at any temperature.
Perceived Malt Aroma & Flavor: Low. In darker versions, any of roasted malt, caramel, or chocolate aroma and flavor attributes should be present at low levels.
Perceived Hop Aroma & Flavor: None to high
Perceived Bitterness: None to high and in balance with fruit character
Fermentation Characteristics: Moderate to intense, yet balanced, fruity esters are present. Diacetyl, DMS, and Brettanomyces should not be present. The evolution of natural acidity at medium-low to high levels develops a balanced complexity and is expressed as a refreshing, pleasant sourness, in harmony with other attributes. 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 kettle or post wort fermentation and is produced by various microorganisms, including certain bacteria and yeasts. Acidic character can be a complex balance of several types of acid and attributes of age. Wood vessels may be used during the fermentation and aging process, but wood-derived flavors such as vanillin should not be present. Attributes arising from liquids previously aged in a barrel, such as bourbon or sherry, should not be present.
Body: Low to high
Additional notes: Fruit aromas, ranging from subtle to intense, should be present. Fruit or fruit extracts, used as an adjunct in either the mash, kettle, primary or secondary fermentation, provide harmonious fruit character ranging from subtle to intense. Beers exhibiting wood-derived attributes or evidence of liquids previously aged in wood are categorized as Fruited Wood-Aged Sour Beer. Within the framework of these guidelines, coconut is defined as a vegetable, and beers containing coconut are categorized as Field Beer. Likewise beers containing chili peppers are categorized as Chili Beer. Fruited versions of Berliner-Style Weisse and Belgian-Style Sour Ale are categorized elsewhere.
