The bottle I have brought home from Mexico a few times is the Tequila Gran Centenario Reposado. Centanario tastes good in all price ranges, but the Reposado tastes smoother and is a great sipper. I had a Don Pilar last year that was excellent, but I can't find it.

I just started drinking Absinthe, and that's some pretty damn good chit too. There's a boutique distillery here in Woodinville called Pacifique that makes some really good stuff.
