National Tequila Day is dedicated to recognizing Tequila, a distilled alcohol made from the blue agave plant. Tequila is the main alcohol ingredient in a Margarita. Blue agave plants produce sugars such as fructose, which are ideal for preparing tequila. The plant only grows in the rich and sandy soil of Jalisco, Mexico at altitudes of 1,500 meters. The origins of National Tequila Day are not well understood, however, it appears that National Tequila Day began to emerge around the late 1990s. This Observance is celebrated every year on July 24.
