Conduct your Tequila Tasting similar to a wine tasting with these items set up on a table: 3 types of 100% agave Tequila: Blanco, Reposado, and Anejo
Glasses for each type of Tequila that will showcase it's qualities
Pitchers of water and a discard container, so guests can rinse their glasses and then pour the water into the container, or use it as a spittoon.
Tasting notes for your Tequila and a description of the types of Tequila displayed on note cards to help guests detect the aromatic nuances and flavor characteristics with each sip.
For an innovative way to taste wine and spirits use the idea of "priming ingredients" as suggested in my article "A Sensuous Wine Tasting Party" for your Tequila Tasting.
