More updates on this...
Beer looks like old old used motor oil. Overall, I got close to my goal of being like Oak agged Yeti by Great divide except for one small bit. I think I can say that I added too much black roast and/or roasted barley.
The initial taste the other weekend left me with a burnt aftertaste. I'm hoping that it'll mellow with time, so the rest of the stout has been sitting in boxes in the back of a cool room now. I don't expect to pull the next one for a few weeks at least.
If nothing else, I think this would make an awesome BBQ sauce. Reduce it with some tomato paste, some peppers, maybe a little honey and some brown sugar(might not need this though). I bet it would be good.
