I'm in central Texas.  Hill country.
Thank you all for the input.  I'm talking about a small-scale, no experience, bathtub-gin type of operation.  I used to drink a lot of beer (Shiner bock) but I've never made any.  This idea occurred to me though, and I thought I'd seek out information.
Anyway, the mesquite beans have a high sugar content and a molasses taste, so I was thinking along those lines...use the beans in a fermentation process or something.  Mesquite wood has a good reputation for smoking barbecue and such, but it's the beans I was considering using.
I'll read through the site as time permits and see what information I can pick up.  Meanwhile, if any of you come across a mesquite beer recipe, please keep me in mind.  I did a web search for mesquite beer and found only one mention:

Thanks again.
