Funny. I went into my local liquor store and asked the very same question. I ended up with Jose Quervo Traditional; limited edition whatever that means. A bottle of liquor will often last me years, but generally not tequila. I have scotch that I have had on the shelf for 20 years and it was already 15 year old scotch. I have to say though, I enjoy sipping on a margarita and love the flavor. I am probably a candidate for an upgrade since I use so little.
