El Tesoro de Don Felipe Tequila and Master Distiller Carlos Camarena are proud to introduce El Tesoro Extra Añejo as a permanent addition to its award-winning tequila portfolio. This tequila has been patiently aged in ex-bourbon barrels for four to five years, with the first batch put in barrels years ago by Camarena's late father, Don Felipe J. Camarena Orozco.
