Clase Azul Ultra is just that - an ultra-premium, extra añejo tequila and our brand’s crown jewel. Ultra is produced in limited quantities and has quickly become a collector and aficionado favorite! Its decanter includes 3 precious metals: pure platinum, sterling silver and 24-carat gold. Clase Azul Ultra is aged for five years in previously used sherry wood casks from Spain, which gives Clase Azul Ultra its unique, refined character.
