New Mexico Pinon Coffee Shop/Cafe?
I've seen it as the "roast of the day" at many different places around town. One, for example, is Friends coffee shop in the street level of the Galleria at Second and Tijeras.
I can't tell you where you can purchase it, as it's not really my thing. Have you checked the supermarkets at all?
BTW, the vast majority of the piñon sold in NM is imported from China. :-) If you don't pick it yourself or know the fellow who picked it, it's not from here. Those fellas at the side of the road with the pickup truckloads of piñon? I doubt they and their grandkids were gathering it all off of bedspreads spread on the ground beneath NM trees . . . . ;-)
So . . . I suspect the roasters aren't using local stuff, either. In fact, there's just no way that they are. Don't know if that matters to you, but it might.
