Single malt refers to whisky that is produced at a single distillery using only malted barley. It must be distilled in pot stills and aged in oak barrels for a minimum of three years. The term "single" indicates that the whisky comes from one distillery, while "malt" signifies the use of malted barley as the primary grain. Single malt whisky is often associated with regions in Scotland, where it is highly regarded for its diverse flavors and characteristics. Each distillery has its unique methods and recipes, resulting in a wide range of taste profiles, from fruity and floral to rich and smoky.
