Tequila Don Julio 70 Anejo Claro Blanco. Don Julio 70 uses carefully selected, fully ripe Weber blue agave and distilled into copper abysses. It is aged for 18 months in Bourbon barrels made of white American oak and then subjected to carbon filtration, to regain the basic citrus notes of a blanco tequila. This creates a combined taste experience, at the beginning notes of citrus and herbs and at the end full, sweet and soft aftertaste.
