Diageo’s brand Tequila Don Julio has expanded its portfolio with the launch of a double-cask tequila offering a distinctive flavour profile.

The new limited-edition Tequila Don Julio Reposado Double Cask is a variant of the company’s traditional Reposado with additional hints of whisky.

The beverage was matured in American white oak barrels for a period of eight months before being finished for 30 days in casks that were previously used to make Buchanan’s Blended Scotch Whisky. It is the company’s first innovation in six years.

Don Julio’s master distiller Enrique de Colsa worked on the tequila for around three years by experimenting with a wide variety of cask options available within the Diageo portfolio.

Colsa said: “I spent three years experimenting with various cask options to perfect the flavour of this variant and I’m proud to introduce it to the US.

“I spent three years experimenting with various cask options to perfect the flavour of this variant and I’m proud to introduce it to the US.”

“I found that finishing the tequila for one month in casks used in the making of Buchanan’s Blended Scotch Whisky allowed me to create a tequila that perfectly balances the core flavour of Tequila Don Julio, as well as the signature flavour of Buchanan’s Blended Scotch Whisky.

“It’s an incredibly unique flavour profile that is excellent enjoyed responsibly neat or on the rocks.”

Later this year, the brand will also introduce the Tequila Don Julio Reposado Private Cask programme, which aims to produce unique tequila variants.

Colsa selected 300 limited-edition barrels for the programme, which were aged for ten months (two months longer than traditional Reposado).

Tequila Don Julio Reposado Double Cask will be available at participating retailers throughout the US for a suggested retail price (SRP) of $59.99.

The Private Cask offering will be available later this year. Each retailer will receive a personalised certificate of authenticity from the brand.

Diageo’s collection of brands includes Johnnie Walker, Crown Royal, Bulleit and Buchanan’s whiskies, as well as Smirnoff, Cîroc and Ketel One vodkas, Captain Morgan, Baileys, Don Julio, Tanqueray and Guinness.

The company’s products are sold in more than 180 countries worldwide.
