manufactured from 100% blue agave (no sugars added), then, by default, that tequila is a mixto (manufactured from at least 51% blue agave). Some tequila distilleries label their tequila as "made with blue agave" or "made from blue agave". However, the Tequila Regulatory Council has stated only tequilas distilled with 100% agave can be designated as "100% agave". Many of the higher-quality, 100% agave tequilas do not impart significant alcohol burn, and drinking them with salt and lime is likely to remove much of the flavor. These tequilas are usually sipped from a snifter glass rather than a shot glass, and savoured instead of quickly gulped. Doing so allows the taster to detect subtler fragrances and flavors that would otherwise be missed. Tequila glasses When served neat (without any additional ingredients), tequila is most often served in a narrow shot glass called a caballito (little horse, in Spanish), but can often be found in anything from a snifter to a tumbler. The Consejo Regulador del Tequila approved an "official tequila glass" in 2002 called the Ouverture Tequila glass, made by Riedel. The margarita glass, frequently rimmed with salt or sugar, is a staple for the entire genre of tequila-based mixed drinks, including the margarita. Cocktails A variety of cocktails are made with tequila, including the margarita, a cocktail that helped make tequila popular in the United States. The traditional margarita uses tequila, Cointreau, and lime juice, though many variations exist. A popular cocktail in Mexico is the Paloma. Also, a number of martini variants involve tequila, and a large number of tequila drinks are made by adding fruit juice. These include the Tequila Sunrise and the Matador. Sodas and other carbonated drinks are a common mixer, as in the Tequila Slammer. Other popular cocktails are the Acapulco cocktail, Bloody Aztec Chimayó Cocktail, Mexican martini, Mojito Blanco and Vampiro. Regulation outside of Mexico Canada Under Canadian regulations (C.R.C., c.870, section B.02.90), any product labelled, advertised, or sold as Tequila must be manufactured in Mexico, as it would be for consumption in Mexico. However, once imported to Canada for sale, it is legal for Tequila to be diluted with distilled or otherwise purified water to adjust it to the desired strength and then sold. United States Similar to the law of Canada, the U.S. law (27 CFR 5.22 (g)) says that tequila must be "manufactured in Mexico in compliance with the laws
