There's a great little shop, CUISH, in the center of Oaxaca City that sells a bunch of different varieties of artisanal mescal made from wild agaves. The agave circled in red in the poster shown above, "papalometl", is the species (Agave cupreata) that I studied in Guerrero (see Mescal and Counting Agaves). The shop is dark and filled with hundreds of little bottles of mescal; tasting is encouraged before buying. [NOTE: The posters are free when you buy a bottle of mescal].
