Real tequila is made from the Blue Agave plant, specifically the Agave Azul Tequilana Weber variety, grown in certain regions of Mexico, including Jalisco, Michoacan, Nayarit, Guanajuato, and Tamaulipas. To be classified as real tequila, it must meet certain standards set by Mexican law, including being made from 100% agave and being bottled in Mexico. The label on the bottle should indicate whether the tequila is blanco, reposado, añejo, or extra añejo, and what percentage of the tequila is made from agave. The label should also state "Product of Mexico" or "Hecho en Mexico" and have the letters CRT, which stands for Consejo Regulador del Tequila, the regulatory agency that ensures companies follow the rules when making tequila. Tequilas that are not 100% agave are called mixtos and are generally of lower quality. The alcohol content of real tequila is typically between 35% and 40% ABV. To ensure that you are drinking real tequila, it is important to read the label carefully and look for these indicators of authenticity.
