Is it a black India pale ale, a cascadian dark ale, an american black ale, an East India export porter, or a NW style black ale? I honestly don't know anymore and that is the most frustrating part of these beers. It's not yet a BJCP recognized style, and yet every brewery under the sun is riding the black ipa wave for giggles or glory. Some examples of this are Stone Sublimely Self Righteous, Shorts Bludgeon Yer Eye PA, Hill Farmstead Jim, and Widmer Brother's Pitch Black IPA.
All of the best examples of this style have had two characteristics worth noting. The first is a clear hop forward presence. It can be Citra, Cascade, Amarillo/Simcoe, etc., but it must be clear and forward. Behind the hops is where the American Black Ale distinguishes itself from an IPA; this is where you'll find a unique maltiness. This malt flavor has notes of a subtle porter; not caramelly, but roasty; not harsh, but additive. The flavors of dark caramel malts, chocolate malts, and de-husked roasted malts are the flavors that work well with hops and add to the flavors. A beer advocate review of Hill Farmstead's Society & Solitude #2, an experimental american black ale, reads:
"A beautiful marriage of pine and roast. Additional notes of chocolate and citrus. Lovely malt body. Medium bodied and easy to drink too quickly."
I found this review spot on with my experience while drinking the beer. I enjoyed it immensely and it helped to challenge my paradigm of what this style was.
