National Scotch Day is observed worldwide on July 27, celebrating the rich tradition of Scotch whisky. This holiday encourages enthusiasts to enjoy a glass of fine Scotch, a type of whisky that has been produced since the late 15th century. Scotch whisky is strictly regulated, requiring it to be distilled in Scotland and aged in oak barrels for a minimum of three years, with an alcohol by volume (ABV) of at least 40%. The drink must not contain any added substances other than water and plain caramel coloring. There are five distinct types of Scotch: single malt, single grain, blended malt, blended grain, and blended Scotch. Notable brands include Bell's, Johnnie Walker, and Chivas Regal, among others. To commemorate National Scotch Day, whisky lovers are encouraged to savor their preferred Scotch, appreciating its unique flavors and heritage.
