Since 1950, tequila has become a drink of distinction, bringing world-renown to a small Mexican town, the town of Tequila. True tequila is made from the Weber blue agave, a relative of the yucca and amaryllis. Agave is harvested when it is 12 years old and the juice after fermentation is known as pulque, it is then distilled in pot stills and creates a fiery drink called mezcal. Distilling for the second time refines the tequila which is aged in wax lined vats to produce white tequila or in oak casks to produce the mellow, gold colored tequila.
