Two basic categories of the spirit drink Tequila can be distinguished according to Mexican law. For the high quality category "Tequila 100% de Agave" only pure agave juice is allowed to be fermented and distilled. Otherwise, the product is a "Mixto-Tequila", which is manufactured by adding up to 49% of sugar to the Agave wort. The sensory analysis using ranking methods showed significant differences between Tequila samples of both categories. The premium products with 100% of Agave were preferred by the test panel. Especially matured products (reposado and anejo Tequilas) had a harmonically mellow aroma and were comparable to premium fruit spirits or whiskies. The worldwide trend leading to a preference of "Tequila 100% de Agave" should be no longer ignored by the German market dominated so far by Mixto-products
