The finishing touch: How aged tequila is being transformed

Traditionally, tequila is aged in white American oak barrels to soften harsh alcohol flavours for a smoother, creamier mouthfeel. However, increasing numbers of producers are experimenting with different cask finishes to explore their effect on the tequila’s aroma, flavours and texture, while luring whisky and wine drinkers.

Each cask can contribute different levels of complexity. However, producers don’t add something just because it is different. It’s important to understand the tequila, then find a cask that enhances what’s already there.

A spirited history

One example is Tequila Ocho Barrel Select Añejo, which is aged in seasoned Cognac casks made from French oak. The aim is to explore not only different wood types but also previous fills.

‘A seasoned Cognac cask brings the characteristics of French oak, but it also brings the history of the spirit that previously occupied it,’ says Jesse Estes, global brand ambassador for Tequila Ocho. ‘The cask has already been used to mature Cognac, so its interaction with the tequila is different from that of a new barrel.’

The goal isn’t to make tequila taste like Cognac, but to understand what the barrel can contribute while preserving the tequila’s identity. ‘We don't want the barrel to become the dominant flavor in the tequila,’ says Estes. ‘We want it to frame the agave.’

Cultural exchange

Casa Dragones Reposado Mizunara is the first tequila aged exclusively in Mizunara casks, a rare Japanese oak known for its use in whisky making.

‘The minerality and character of the agave remain very present,’ says Bertha González Nieves, co-founder and CEO at Casa Dragones Tequila. ‘It’s complemented by these delicate characteristics of Japanese oak.’

For Nieves, it’s about more than adding a unique dimension to her spirit. The relationship between the agave and Mizunara portrays something bigger. ‘It represents a beautiful meeting of both Mexican and Japanese cultures,’ she says. ‘Thanks to extraordinary traditions of craftsmanship.’

Food fusion

José Cuervo’s Reserva de la Familia Private Cask Collection Edition No2 is the world’s first tequila finished in mole-seasoned barrels, paying homage to one of Mexico’s most notable dishes – a complex savoury sauce.

‘A key challenge was translating mole’s complex flavour into wood,’ says Alejandro Coronado, Maestro Tequilero for Reserva de la Familia. ‘We created a specialty Oaxacan red mole paste that was added directly to the interior of new American oak barrels, allowing the wood to absorb those deep, layered compounds.’

The barrels were then thoroughly rinsed and filled with the brand’s añejo tequila. The result was an expression unlike anything before. ‘What makes this approach so unique is that nothing is added directly to the liquid,’ says Coronado. ‘The wood does all the work.’

Speciality casks

Returning to France, Don Fulano Reposado is made with mature highland agave and aged in French Limousin oak from southwest France, which adds distinct character to the spirit.

‘French Limousin’s elegant and subtle dry spice character complements the natural roundness of our mature highland agave base,’ says Sergio Mendoza, co-founder of Don Fulano. ‘Our aim is to let the product express itself through its long maturation without letting the barrel dominate with over-woodiness.’

But the cask experimentation doesn’t stop there. ‘We like to play with specialty casks, such as with oloroso and amontillado Sherry or Calvados,’ explains Mendoza. ‘This provides more subtle finishes or coupages.’

Whisk(e)y galore

Tequila Partidas Añejo is aged in ex-bourbon barrels before finishing in Sherry-seasoned ex-single malt Scotch casks for expansive complexity and depth.

‘Ex-bourbon contributes a rounder and softer texture, complementing the natural cooked-agave profile very well,’ says José Valdez, Master Tequilero at Tequila Partida. ‘The ex-single malt Scotch sherry-seasoned casks take the tequila in another direction with additional depth and complexity.’

Using different casks not only helps producers deepen their understanding of the craft behind maturation, but also see what is possible.

‘Innovation in tequila is about having the courage to explore, but also the discipline to know when to say no,’ says Valdez. ‘My role is not simply to create something new, but to make sure that what we create respects the agave.’
