IPA Sub-Styles

The IPA Explosion

No beer style has spawned more sub-styles than the India Pale Ale. What began as a single style has fragmented into a diverse family, each variation exploring a different aspect of hop character.

West Coast IPA

The classic American IPA. Clear to brilliant gold, aggressively bitter (60-80+ IBU), bone-dry finish, and resinous/piney/citrus hop aroma. The malt backbone is deliberately restrained — a clean canvas for hops. Prominent examples: Russian River Blind Pig, Firestone Walker Union Jack, Alpine Nelson.

New England / Hazy IPA

A revolution in hop expression. Hazy IPAs prioritize juicy aroma and soft mouthfeel over bitterness. Characteristics include permanent haze (from oats, wheat, and hop polyphenols), a creamy, pillowy body, massive dry hop additions, and tropical/citrus/stone fruit aroma. Bitterness is moderate (40-70 IBU) but perceived as low due to the soft body.

Double / Imperial IPA

The amplified IPA. 7.5-10% ABV with enormous hop additions but, in the best examples, still balanced and dangerously drinkable. Simple sugar (10-15% of fermentables) lightens the body. Both West Coast (dry, bitter) and hazy (juicy, soft) double IPAs exist.

Session IPA

A lower-ABV IPA (3.5-5%) that attempts to deliver full hop character at reduced strength. The challenge is achieving hop intensity without the malt backbone that normally supports it. Light body and crispness are features, not flaws.

Brut IPA

An ultra-dry IPA where enzymes (amyloglucosidase) break down all residual dextrins, producing a bone-dry, champagne-like body. High carbonation and exclusive late/dry hop additions create an effervescent, aromatic beer with zero sweetness. A brief trend that produced some outstanding examples.

Black IPA / Cascadian Dark Ale

An IPA with the color and mild roast character of a porter or stout. Dehusked dark malts (Carafa Special, Midnight Wheat) provide color without harsh roast. Hop character remains dominant. An interesting stylistic exercise, though not as commercially successful as other IPA variants.

Red IPA

A malt-forward IPA with significant Crystal malt additions for amber-red color and caramel sweetness. The malt provides a richer, more complex backdrop for the hops. Balances the hop-forward IPA approach with a stronger malt presence.

White IPA

A cross between a Belgian Witbier and an American IPA. Wheat malt, Belgian yeast (subtle spice and fruit), and American hops (citrus and tropical). Often includes coriander and orange peel. An interesting fusion that combines the best of both worlds.

Cold IPA

A recent innovation: an IPA brewed with lager yeast (or ale yeast at cold temperatures) and adjuncts (rice, corn) for an ultra-clean, crisp, dry base that showcases hops. Think of it as a highly hopped lager.

Milkshake IPA

A hazy IPA with lactose for sweetness and body, often combined with fruit and vanilla. Dessert-like and polarizing, but undeniably popular.
