Double (Imperial) India Pale Ale Traits

Click the below buttons for a more detailed description of Double (Imperial) India Pale Ale style traits

Beer Style Description

Imperial or Double India Pale Ales have intense hop bitterness, flavor and aroma. Alcohol content is medium-high to high and notably evident. They range from deep golden to medium copper in color. The style may use any variety of hops. Though the hop character is intense it’s balanced with complex alcohol flavors, moderate to high fruity esters and medium to high malt character. Hop character should be fresh and lively and should not be harsh in quality. The use of large amounts of hops may cause a degree of appropriate hop haze. Imperial or Double India Pale Ales have medium-high to full body. Diacetyl should not be perceived. The intention of this style of beer is to exhibit the fresh and bright character of hops. Oxidative character and aged character should not be present. Bigger than either an English or American IPA in both alcohol strength and overall hop level (bittering and finish). Less malty, lower body, less rich and a greater overall hop intensity than an American Barleywine. Typically not as high in gravity/alcohol as a barleywine, since high alcohol and malt tend to limit drinkability. A showcase for hops.

60-120

Aroma

A prominent to intense hop aroma that can be derived from American, English and/or noble varieties (although a citrusy hop character is almost always present). Most versions are dry hopped and can have an additional resinous or grassy aroma, although this is not absolutely required. Some clean malty sweetness may be found in the background. Fruitiness, either from esters or hops, may also be detected in some versions, although a neutral fermentation character is typical. Some alcohol can usually be noted, but it should not have a “hot” character.

Appearance

Color ranges from golden amber to medium reddish copper; some versions can have an orange-ish tint. Should be clear, although unfiltered dry-hopped versions may be a bit hazy. Good head stand with off-white color should persist.

Flavor

Hop flavor is strong and complex, and can reflect the use of American, English and/or noble hop varieties. High to absurdly high hop bitterness, although the malt backbone will generally support the strong hop character and provide the best balance. Malt flavor should be low to medium, and is generally clean and malty although some caramel or toasty flavors are acceptable at low levels. No diacetyl. Low fruitiness is acceptable but not required. A long, lingering bitterness is usually present in the aftertaste but should not be harsh. Medium-dry to dry finish. A clean, smooth alcohol flavor is usually present. Oak is inappropriate in this style. May be slightly sulfury, but most examples do not exhibit this character.

Mouthfeel

Smooth, medium-light to medium body. No harsh hop-derived astringency, although moderate to medium-high carbonation can combine to render an overall dry sensation in the presence of malt sweetness. Smooth alcohol warming.
