Top shelf tequila will probably kill you more easily, it’s filtered and very mild compared to more plebeian, rough tasting brands. I went to dinner with friends several weeks ago to a new place, they had Roca Patrón Silver on the rocks as a drink special, six bucks, so we said what the heck and ordered a round, then another before dinner. Very nice, not head-spinning or really even strong tasting. Very mild, a little citrus, a little peppery, pleasant to drink straight over rocks and I never thought I’d ever say that about tequila.
Actually tequila “neat” is my favorite sipping drink. It’s amazingly delicious in tiny sips. The flavors are more intriguing than fine scotch with the right brand. I recommend Clase Azul, either platinum or reposado for a very full flavor.
