Tequila

Tequila is a distilled beverage, made only from a specific cultivar of Agave Tequilana called 'Weber Azul' or Blue Agave, native to the states of Jalisco, Colima, Nayarit and Aguascalientes in Mexico. The Blue Agave grows above an altitude of 1500 m and are juicy succulents with spiky fleshy leaves.

Tequila is made around the city of Tequila 40 miles northwest of Guadaljara, and in the Jaliscan Highlands of Central Western Mexico. Mexican laws state that Tequila can only be produces in the state of Jalisco and a few limited municipalities in the other Blue Agave growing regions.

Tequila is 35% to 55% Alcohol by Volume (70 and 110 U.S. proof), it must be at least 40% ABV to be sold as Tequila in the USA.

Tequila is a distilled derivative of the pre-Columbian fermented beverage called pulque, made from the Agave plant. When the Spanish conquistadors ran out of their brandy, they started distilling Agave to produce a distilled spirit. This by 1600s was what Don Pedro Sánchez de Tagle, the Marquis of Altamira, began mass-producing in his distillery near modern day Jalisco and came to be known as Tequila.

Wild Turkey 80 Proof Bourbon

American's don't need to be lectured on Bourbon, but still, let's put it in record like all other spirits. A Bourbon in American spirit is a barrel-aged distilled liquor made primarily from corn. The name might have been derived from the French Bourbon dynasty, or from Bourbon County in Kentucky, or Bourbon Street in New Orleans, both named after the French Dynasty.

Technically, most whiskey made in America are legally classified as Bourbon, although Bourbon is in spirit a Southern Whiskey with special connection to Kentucky. Note than although Tennessee Whiskey is classified as Bourbon, Tennessee distilleries do not prefer their whiskey to be unique and referred to as Tennessee Whiskey only.

Distilling came to Kentucky in the late 18rth Century with the Scots, Scot-Irish and other settlers including English, Welsh, German and French, and they brought with them their distilling techniques and ageing processes in charred oak barrels. The charring is what gives the Bourbon the brownish colour and distinctive taste.

To be a legal Bourbon, a whiskey has to meet the following criteria

Produced in the United States and Territories (Puerto Rico) and the District of Columbia
Made from a grain mixture that is at least 51% corn
Aged in new, charred oak containers
Distilled to no more than 160 (U.S.) proof (80% alcohol by volume)
Entered into the container for aging at no more than 125 proof (62.5% alcohol by volume)
Bottled (like other whiskeys) at 80 proof or more (40% alcohol by volume)
