Want to get a taste of authentic Tequila? Please, toss out your crocs, put on some walking shoes, and cross over to Nogales, Sonora. Here’s why: In Mexico, Tequila is 32-35% alcohol. For some reason, when that same bottle crosses over to the U.S., it gets bumped to 40%, completely changing the taste. Below is my personal recommendation: Herradura Ultra Anejo.
