Mezcal: Mezcal, sometimes spelled mescal, is a distilled alcoholic beverage made from any type of agave. The word mezcal comes from Nahuatl mexcalli, which means "oven-cooked agave", from metl and ixcalli. Traditionally the word "mezcal" has been used generally in Mexico for all agave spirits and it continues to be used for many agave spirits whether these spirits have been legally certified as "mezcal" or not, and it is also considered a drink of artisan origin. Agaves or magueys are endemic to the Americas and found globally as ornamental plants. More than 70% of mezcal is made in the Mexican state of Oaxaca, but is now produced and commercialized throughout Mexico for the national and international market. A saying attributed to Oaxaca regarding the drink is: "Para todo mal, mezcal, y para todo bien, también; y si no hay remedio litro y medio" ("For all bad, mezcal, and for all good, as well; and if there is no remedy, liter and a half"). Native fermented drinks from maguey plant, such as pulque, existed before the arrival of the Spanish. The origin of mezcal is tied to the introduction of distillation technology from Spanish immigrants to Nueva Galicia (present-day Aguascalientes, Colima, Guanajuato, Jalisco, Nayarit, and Zacatecas) in the late 16th century.
Tequila: Tequila is a distilled beverage made from the blue agave plant, primarily in the area surrounding the city of Tequila 65 km (40 mi) northwest of Guadalajara, and in the Jaliscan Highlands (Los Altos de Jalisco) of the central western Mexican state of Jalisco. The red volcanic soils in the region of Tequila are well suited for growing the blue agave, and more than 300 million of the plants are harvested there each year. Agave grows differently depending on the region. Blue agaves grown in the highlands Los Altos region are larger and sweeter in aroma and taste. Agaves harvested in the valley region have a more herbaceous fragrance and flavor. Due to its historical and cultural importance, the region near Tequila was declared a UNESCO World Heritage Site in 2006, the Agave Landscape and Ancient Industrial Facilities of Tequila.
