I was eating fried lamb testicles at a dinner party a few weeks back when a tall man at the end of the table raised a bottle overhead and roared: "AHHHH! Bacanora! It tastes like the deserts of Meh-he-co!" The bottle then made its way around the table, eliciting both grimaces and nods of approval.

I had to drive back to my hermitage out of town, so I did not partake. But it’s been nagging me since: What is this bacanora, and why do men drop forkfuls of lamb testicles to sing its praises?

The answer came today when I read up on Hotel Congress’ third-annual AgaveFest, which takes place from 6 to 9 p.m., Thursday, May 5. It will include tastes of more than 40 different tequilas, mezcals and sotols and a cocktail competition, among all sorts of other revelry.

And bacanora will also be available for tasting. It is apparently an "agave-derived liquor made in Sonora that was illegal to distill until 1992," according to the Hotel Congress website. Sounds pretty interesting, and well worth checking out this Cinco de Mayo.

Tickets to the event are $25, and that includes tastes of 12 different liquors. There’s more information over here.
