There's no such thing. Tequila is nasty poor man's liquor, only made palatable to yuppy palates by insisting you can only enjoy it by inbibing in a taste bud numbing cocktail of salt and lime juice before you drink it.

That said, I enjoy a good (=nasty) tequila every now and then. Just like I enjoy a good glass of paint thinner aka Moutai on occasion: give the ol' taste buds a little workout.
