Happy National Scotch Day!
Scotch whisky by law must be distilled and aged in Scotland from malted barley and, sometimes, other grains. If it’s made with just malted barley and water and bottled as whisky from one distillery, it’s one of the famous “single malt” Scotch whiskies. If a Scotch is made with other grain, it’s referred to as “single grain.” There are also blended Scotches (such as Johnnie Walker) that use whiskies from multiple distillers.
The Jon Taffer Drink: Dry Godfather

Pour 1.5 oz of Johnnie Walker Blue and add a few drops of Amaretto in a rocks glass over ice.
