Oro, meaning "gold," tastes similar to blanco and costs about the same. Remember to choose 100% agave tequila. Mixtos may be cheap, but a nasty headache in the morning is expensive. You don't have to go through the salt-and-lime routine if you don't want to. (Most Mexicans don't drink tequila this way, anyway.) Take room-temperature tequila, pour it into a shot glass, toast, and pour it down your gullet.
