From Tequila Gringo:

Another great one from the good folks at El Mayor.  We served this to some friends of ours and they all were shocked that tequila could be so good.  In fact, two emailed me the next day to get the name again because they wanted to buy some.  We picked up caramel (and we love when we pick up caramel) a medium heat and a delicious richness.  This 100% agave tequila is aged for up to 3 years in white oak barrels.

From El Mayor:

 100% Agave Tequila

• El Mayor Añejo is 100% agave tequila made at the Gonzãlez family-owned distillery under the watchful eye of tequila master Rodolfo Gonzãlez.

• The El Mayor portfolio also includes El Mayor Reposado and El Mayor Blanco, offering a taste for every connoisseur of fine spirits.
   

Process

• El Mayor Añejo begins with the Blue Tequilana Weber agave grown in the Highlands of Jalisco, where natural conditions produce a larger, sweeter heart that yields the unique characteristics demanded of El Mayor tequila.
• It is double-distilled under time-honored, traditional methods enhanced by the technology in the state-of-the-art Gonzãlez factory, a combination resulting in the highest quality, premium tequila.  
• Prior to bottling at 80 proof in 750 mL bottles, the tequila undergoes a personal tasting by Rodolfo Gonzãlez. Every bottle is unique as each is hand labeled, numbered and signed with Rodolfo’s approval.
