When we were growing up on the Mexican border, you could buy a bottle of Oso Negro (which means black bear but some swore it translated into "blindness in a bottle"). You could get vodka, gin, bourbon or scotch. Gin was vodka plus a splash of Pine-Sol floor cleaner, bourbon was vodka with a little more caramel coloring added and scotch was vodka with less caramel color added. It was dirt cheap and back then the alcohol content was scary high. I'm not sure anyone even knew how high it was or if there was any consistency. But you could pour some down the carburetor of nearly any engine and have it kick right over. I've read they just make vodka and gin now and they've taken steps to gentrify their image.
