India Black Ale, IBA.
Let's get it going.
IMO, I don't even know if there should be an 'I' in with the 'P & A", let alone the 'P'.
It's not a historic style, so the "India" can go.
It's not "Pale" either so that can be tossed out.
Calling it a Black IPA is an oxymoron (Black India
Pale Ale?)
I like Cascadian Dark Ale, or Cascadian Black Ale. I don't think the Cascadian will stick whatsoever, the BA has already named it as a category at this years GABF, and if the BJCP adopts this "new" style, I'd assume they will call it what it will be
known as best.
I know all the folks up in northern Calfornia, Oregon, Washington, and Canada want to take credit for this "style", which they may very well be entitled to, however, I just don't see Cascadia sticking with the title. One reason is I've never seen a region (other than a mountain range, which is the Cascade Range) on a map listed as Cascadia.
Regardless of what folks locally call the area, or what folks would like the area to be called, I think the vast majority of the eastern United States do not know the upper northwest as Cascadia. I could be wrong, and I'm sure someone will point out some shortcoming in my argument.
Either way it is just my opinion.
