Single malt is a type of whisky made from malted barley at a single distillery. It must be produced in a pot still and aged for a minimum of three years in oak barrels. The term "single" indicates that all the whisky comes from one distillery, while "malt" refers to 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 unique flavors and characteristics. Each distillery imparts its own style, influenced by factors like local water sources, climate, and production methods.
