14. India Pale Ale (IPA)
Styles
14A. English IPA
Aroma: A moderate to moderately high hop aroma of floral, earthy or fruity nature is typical, although the intensity of hop character is usually lower than American versions. A slightly grassy dry-hop aroma is acceptable, but not required. A moderate caramel-like or toasty malt presence is common. Low to moderate fruitiness, either from esters or hops, can be present. Some versions may have a sulfury note, although this character is not mandatory.
Appearance: Color ranges from golden amber to light copper, but most are pale to medium amber with an orange-ish tint. Should be clear, although unfiltered dry-hopped versions may be a bit hazy. Good head stand should persist.
Flavor: Hop flavor is medium to high, with a moderate to assertive hop bitterness. The hop flavor should be similar to the aroma (floral, earthy, fruity, and/or slightly grassy). Malt flavor should be medium-low to medium-high, but should be noticeable, pleasant, and support the hop aspect. The malt should show an English character and be somewhat bready, biscuit-like, toasty, toffee-like and/or caramelly. Despite the substantial hop character typical of these beers, sufficient malt flavor, body and complexity to support the hops will provide the best balance. Very low levels of diacetyl are acceptable, and fruitiness from the fermentation or hops adds to the overall complexity. Finish is medium to dry, and bitterness may linger into the aftertaste but should not be harsh. If high sulfate water is used, a distinctively minerally, dry finish, some sulfur flavor, and a lingering bitterness are usually present. Some clean alcohol flavor can be noted in stronger versions. Oak is inappropriate in this style.
Mouthfeel: Smooth, medium-light to medium-bodied mouthfeel without hop-derived astringency, although moderate to medium-high carbonation can combine to render an overall dry sensation in the presence of malt sweetness. Some smooth alcohol warming can and should be sensed in stronger (but not all) versions.
Overall Impression: A hoppy, moderately strong pale ale that features characteristics consistent with the use of English malt, hops and yeast. Has less hop character and a more pronounced malt flavor than American versions.
History: Brewed to survive the voyage from England to India. The temperature extremes and rolling of the seas resulted in a highly attenuated beer upon arrival. English pale ales were derived from India Pale Ales.
Comments: A pale ale brewed to an increased gravity and hop rate. Modern versions of English IPAs generally pale in comparison (pun intended) to their ancestors. The term "IPA" is loosely applied in commercial English beers today, and has been (incorrectly) used in beers below 4% ABV. Generally will have more finish hops and less fruitiness and/or caramel than English pale ales and bitters. Fresher versions will obviously have a more significant finishing hop character.
Ingredients: Pale ale malt (well-modified and suitable for single-temperature infusion mashing); English hops; English yeast that can give a fruity or sulfury/minerally profile. Refined sugar may be used in some versions. High sulfate and low carbonate water is essential to achieving a pleasant hop bitterness in authentic Burton versions, although not all examples will exhibit the strong sulfate character.

14B. American IPA
Aroma: A prominent to intense hop aroma with a citrusy, floral, perfume-like, resinous, piney, and/or fruity character derived from American hops. Many versions are dry hopped and can have an additional grassy aroma, although this is not required. Some clean malty sweetness may be found in the background, but should be at a lower level than in English examples. Fruitiness, either from esters or hops, may also be detected in some versions, although a neutral fermentation character is also acceptable. Some alcohol may be noted.
Appearance: Color ranges from medium gold 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 should persist.
Flavor: Hop flavor is medium to high, and should reflect an American hop character with citrusy, floral, resinous, piney or fruity aspects. Medium-high to very high hop bitterness, although the malt backbone will support the strong hop character and provide the best balance. Malt flavor should be low to medium, and is generally clean and malty sweet although some caramel or toasty flavors are acceptable at low levels. No diacetyl. Low fruitiness is acceptable but not required. The bitterness may linger into the aftertaste but should not be harsh. Medium-dry to dry finish. Some clean alcohol flavor can be noted in stronger versions. Oak is inappropriate in this style. Some sulfur may be present if sulfate water is used, but most examples do not exhibit this character.
Mouthfeel: Smooth, medium-light to medium-bodied mouthfeel without hop-derived astringency, although moderate to medium-high carbonation can combine to render an overall dry sensation in the presence of malt sweetness. Some smooth alcohol warming can and should be sensed in stronger (but not all) versions. Body is generally less than in English counterparts.
Overall Impression: A decidedly hoppy and bitter, moderately strong American pale ale.
History: An American version of the historical English style, brewed using American ingredients and attitude.
Ingredients: Pale ale malt (well-modified and suitable for single-temperature infusion mashing); American hops; American yeast that can give a clean or slightly fruity profile. Generally all-malt, but mashed at lower temperatures for high attenuation. Water character varies from soft to moderately sulfate.

14C. Imperial IPA
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 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 sweet 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. Some sulfur may be present if sulfate water is used, but most examples do not exhibit this character.
Mouthfeel: Smooth, medium-light to medium-full 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.
Overall Impression: An intensely hoppy, very strong pale ale without the big maltiness and/or deeper malt flavors of an American barleywine. Strongly hopped, but clean, lacking harshness, and a tribute to historical IPAs.
History: A recent American innovation reflecting the trend of American craft brewers "pushing the envelope" to satisfy the need of hop aficionados for increasingly intense products. Category may be stretched to cover historical and modern American stock ales that are stronger, hoppier ales without the malt intensity of barleywines. The adjective "Imperial" is arbitrary and simply implies a stronger version of an IPA; "double," "extra," "extreme," or any other variety of adjectives would be equally valid.
Comments: 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. Not necessarily as high in gravity/alcohol as a barleywine. A showcase for hops.
Ingredients: Pale ale malt (well-modified and suitable for single-temperature infusion mashing); can use a complex variety of hops (English, American, noble). American yeast that can give a clean or slightly fruity profile. Generally all-malt, but mashed at lower temperatures for high attenuation. Water character varies from soft to moderately sulfate.
Vital Statistics:OG FG IBUs SRM ABV 1.075 - 1.090+ 1.012 - 1.020 60 - 100+ 8 - 15 7.5 - 10+% Commercial Examples: Dogfish Head 90-minute IPA, Rogue I2PA, Stone Ruination IPA, Three Floyd's Dreadnaught, Russian River Pliny the Elder, Moylan's Moylander Double IPA.
