BrewBlog: Double IPA

Specifics

Style:

Category:	India Pale Ale (IPA)
Number:	14C

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. Drinkability is an important characteristic; this should not be a heavy, sipping beer. It should also not have much residual sweetness or a heavy character grain profile.

Commercial Examples: Russian River Pliny the Elder, Three Floyd’s Dreadnaught, Avery Majaraja, Bell’s Hop Slam, Stone Ruination IPA, Great Divide Hercules Double IPA, Surly Furious, Rogue I2PA, Moylan’s Hopsickle Imperial India Pale Ale, Stoudt’s Double IPA, Dogfish Head 90-minute IPA, Victory Hop Wallop.

Comments

I wanted to use up all of the remaining Cascades from the 2008 harvest and this seemed like the best way to do it. In total, 7.35 oz of hops will be used for this batch.
