AG#58 – Death Star Black IPA

IMG_2814
I posed a question on Twitter (@BubblesBrews) recently, asking if it was safe to brew a black IPA again, now that all the trendy brewers are putting grapefruit and salt in their brews. At one stage in 2014/2015, it seemed like every craft brewery was coming out with a hoppy black IPA.
In my own recipe for black IPA, I am attempting to push those coffee flavours to the forefront by using Carafa Special III and Chateau Light Cafe Malt. I’m trying not to go overboard with the percentages of these malts as I don’t want something that is too roasty or acrid. I want more coffee than burnt toast. I also want some caramel character to balance the high hop bitterness and for this I’ll be using a combination of Crystal 40 and Crystal 60 malts. Hops will be whatever smells fresh when I open the bags. As usual, I’ve got a bit of a backlog in the hop drawer at the moment, so I want to use some of them up. But I’ll probably use a combination of Cascade, Centennial and Simcoe.

01/07/2016 – First taste and it’s an absolute cracker. Quite similar in hop character to the American stout I did last year, but much less roasty. Great aroma, classic pungent American hop flavour. Toasty, biscuity malt. Good balance with the bitterness. A keeper.
