Scotch whiskey (often referred to as "Scotch" or "Scotch Whiskey") is a malt whiskey made in Scotland. It was originally produced from barley malt, but in the eighteenth century distilleries began to market them where they are made from wheat and rye.
Scotch whiskey is divided into five distinct categories: single malt, single grain, blended malt (initially called vatted malt or pure malt), blended and blended grain. All Scotch whiskeys must undergo maturation (aging) in oak barrels for at least three years. Any age information on a whiskey bottle, expressed numerically, needs to reflect the age of the newest whiskey used to produce that product. A whiskey with the information of its age is known as "guaranteed-age".
The first citation of Scotch whiskey dates back to 1495. A monk named John Cor was the distiller of Lindores Abbey in the Kingdom of Fife.
