You can't call the spirit made here tequila—not legally, anyway—since that name is reserved by a denomination of origin status to blue agave liquor produced in the state of Jalisco. Still, the tour of the Los Osuna distillery is no less interesting because of that. You'll learn about tequila and Mexican spirits generally, as guides spend time explaining the so-called Tequila Wars. Want to know what the difference is between tequila and Los Osuna's blue agave spirit? You'll be able to taste both and see if you can tell them apart before the tour concludes.
