Tuxca
The word tuxca originated in Colima and was used by people in the city of Colima to describe mezcal that arrived in clay jugs from the Zapotitlan de Vadillo and Tuxcacuesco region of Jalisco. The name tuxca, of course comes from the name of the latter town, Tuxcacuesco, and the term was used to refer to vino mezcal from that region.
There is a group of people that is actively working with the Mexican government to establish a Denomination of Origin for tuxca, similar to that of tequila or mezcal. This would mean that only spirits made in this region of Jalisco could be called tuxca, because there is historical significance of the term and the tuxca production in this area.
