El Tesoro brought a collection of oak barrels that previously held the legendary Booker’s 30th Anniversary Bourbon from Kentucky to La Alteña. Having aged Booker’s for up to 16 years, the casks remained rich with the vanilla flavor loved by Fred Noe. These exceptional barrels held safe this extra añejo tequila for at least 36 months, each tapped only when it was at the peak of its maturity.
