Single malt whisky is a whisky that is made from 100% malted barley and is produced at a single distillery. Single malt whiskies are typically aged for at least three years before being bottled and sold. These whiskies tend to be more complex and flavorful than other whiskies, such as blended Whiskies or grain whiskies. The difference between Cognac, Armagnac, and other brandies is that whiskies are made from grain rather than grapes.
