According to the Jose Cuervo website, it all began in 1795, when Jose María Guadalupe de Cuervo was producing his Mexcal wine spirit commercially having obtained an official permit for this purpose from the King of Spain. By 1812, he had established La Rojena, the distillery which to this day produces Jose Cuervo Tequila. By 1844, Jose Cuervo Tequila was being distributed within Mexico, and in 1873 the earliest known documented export of the Tequila outside of Mexico apparently occurred when 3 bottles of Jose Cuervo were transported across the United States border by donkey. As you know, those exports have continued (although no longer by donkey), and now the Jose Cuervo brand is the best-selling tequila in the entire world.
The Jose Cuervo Especial is available as both a Gold or ‘joven’ tequila and as a Silver or ‘plata’ tequila. These tequila spirits are not made from 100 % blue agave which means that they are referred to in the industry as “Mixto“. A Mixto tequila must have at least 51 % of its volume made from blue agave distillate, but the other 49 % can be distilled from other non agave sugars (usually sugar cane). Mixto is also subject to less stringent regulation with respect to additives such as sugar syrup and caramel.

(In July of 2013, Proximo Spirits acquired the distribution rights for the Jose Cuervo brand in supplanting Diageo, who had managed the brand since 1997.)

Review: Jose Cuervo Especial Plata (Silver)
Although this review was originally published two years ago, I have updated it to contain more current information and added a new cocktail suggestion, the Dreadful Lemon Sky. This Margarita style cocktail is based upon the Picador, a recipe which predates the margarita by several decades.
Please enjoy my updated review, and the cocktail suggestions which follow it. Cheers!
