Clase Azul Ultra is an ultra-premium and the brand’s crown jewel. House in a beautiful decanter that is made using not one, not two, but three precious metals. pure platinum, sterling silver and 24-carat gold. The spirit itself is aged in Sherry wood for five years, an incredibly long time for a Tequila. The result is a rich, dark amber spirit with notes of exotic fruit, caramel and vanilla. Rounded and full, this is sipping Tequila par excellence.
