I am gathering ingredients for a Black IPA I plan on brewing in a week or two. My LHBS didn't have 90L Crystal on hand so I picked up some 120L Crystal to substitute.

What type of differences will come from this substitution? This will be steeped for 30 minutes at 155 F.

120L Crystal has more of a burnt raisin flavor than 90L. They are both darker crystals, so the flavor profile isn't too different, but they are different enough. How much are you using in your recipe?

Here is the steeping bill:

0.5 lb British Black Patent
0.5 lb Carafa III
1 lb 60L Crystal
0.5 lb 90L Crystal
0.5 lb Roasted Barley

I imagine that the black patent and roasted barley will be the dominant grains in this recipe but I am going for a Black IPA so there is be a lot of hops in the schedule.

That's more like an American Stout (with the assumption of the hops you're adding). It's not really a Black IPA at all - you won't that much black patent or roasted barley in a Black IPA. I'd stick with a dehusked Carafa plus possibly a touch of chocolate malt to get your color while not overpowering the taste with the roasted grains.

I agree with Pseudo Chef. Ditch the roast barley and the black patent. Up the carafa to a full pound. You've got a hoppy stout there.

OK. So switch out the Patent and roast barley for more carafa and what else?

Agree with the rest. That's somewhere in the porter/stout category, not IBA. You will get some significant roast from that level of roasted grains.

Looks like an interesting beer, could be very tasty. Still, if all 7 billion people on Earth call that an IPA, I still won't agree.

The dark crystal is going to darken that beer a bit by itself. With a half pound of Carafa, it'll be midnight black. and I'm throwing another vote to remove the BP and roast barley from there, unless you are shooting for a hoppy stout, not an IPA.

That's about it. If you're really looking for suggestions, I'd drop the crystal 60 down to .5lb for a total of 1lb of crystal, but that's just my taste. The important thing is dropping the RB and black patent, and upping the carafa III to 1lb. Carafa will contribute color, and a little flavor, but won't give any of those burnt, roasted, acrid flavors that you don't want in a Black IPA
