I used to go to a Mexican place that used beer in the beans. The idea is to put it in with the beans, when they're first boiling. The alcohol boils out and leaves the flavor. I have these three micro's from Red Rocks that were left in my cooler, so I'm going to use them this batch. (Thanks Jade!) If it tastes OK I'm planning on using Guinness stout next time. That will really add some flavor.
The rest of the batch is basically the same. Roasting the tomato's, garlic, jalapeno's, and green pepper, and adding some dark chocolate at the end.
I've been told to add some 'bottom' flavor, and we've had some pretty good discussions on how to do so. I figure I'll give it a try, and give me some ground to compare what the Guinness will taste like.
