I made a stout with chipotle pepper and it tasted great! I used about 1/2 oz in the boil and 1/2 oz in the secondary. Since the peppers are smoked to begin with, the peppers added a nice smoked wood flavor to the beer and gave it a little warmth. I would not call the beer spicy by any means but it really added some complexity with a little "afterburn". I will definitely be experimenting with chipotle again. Sounds like with the smoked malt and the chipotle you will have a very smokey beer. Good luck on your brew!
