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. Dark amber color. Silky, rich and full body. Aromas of wood, fruit, intense sherry notes with hints of caramel and vanilla. The taste is smooth, flavorful, elegant with hints of sweet and oak.
