What is "espolon"

Tequila El Espolòn is a brand of tequila from Campari America, the sixth largest spirits company in the United States. The tequila is produced by the San Nicolas Distillery in the Los Altos (Highlands) region of Jalisco, Mexico, famous for its cultivation of agave plants.

Made entirely from blue agave, El Espolòn (or simply, Espolòn) was created by Cirilo Oropeza, and was first produced in 1998. It is currently distributed in Mexico, the United States and select markets elsewhere. It is the first tequila to release variants of reposado.
