To taste true tequila find a bottle that states 100% agave then decide between these varieties:
Blanco (White) also called Plata (Silver) Tequila
Agave in its purest form, straight from a stainless steel vat to the bottle, without aging. Clear in color, light in body with sharper alcohol and true agave flavors and intensity as well as the natural sweetness. Fresh cut apple, pear, citrus and vegetal fresh herb notes like fresh cut and lemon grass.
Aged in wooden casks or tanks from two to eleven months. The most popular style of tequila in Mexico. Golden hued with a robust, spicy, peppery taste balancing agave and wood with hints of almond vanilla, butterscotch, honey and oak.
Aged in oak for a minimum of one year (three + for extra anejo). Darker colors, smoother, fuller mouth feel and long finish imparted by oils from the oak. Agave may be almost hidden. Chocolate, caramel, stronger butterscotch, burnt honey, sweet potato (yam), vanilla and sometimes tobacco or leather tastes.
Aged more than three years. Even darker, more mahogany color, and is so rich that it becomes difficult to distinguish it from other quality aged spirits. Frowned upon by many tequila purists for lacking most of the agave flavour but loved by others it is the most expensive tequila available.
Beware of tequila not labeled 100% agave. These are “mixtos” or blends comprised of as little as 51% agave (the minimum amount required by law to be called tequila) and 49% alcohol made from other sugars usually corn or sugar cane.
Also avoid tequilas labeled “gold” as these are typically mixtos that are colored with caramel. This artificial color implies that the tequila was aged in oak but instead only causes hangovers.
