Jose Cuervo Especial Silver Tequila comes from the oldest distillery still in operation in South America, founded in 1758 when Jose Antionio de Cuervo was granted a piece of land in the Mexican state by the King of Spain to cultivate agave. The blue agaves are distilled and bottled at 38% alcohol. Tequila Especial Silver impresses with its fresh and light taste, with an agave content of over 50%.
