Single malt Scotch whisky is a type of whisky made from malted barley and produced at a single distillery in Scotland. It must be aged in oak barrels for a minimum of three years, which contributes to its unique flavor profile. The term "single" indicates that it comes from one distillery, while "malt" refers to the use of malted barley as the primary grain. To be classified as Scotch, the whisky must adhere to strict regulations set by the Scotch Whisky Association. This includes being distilled and matured in Scotland and having an alcohol content of at least 40%. Single malt Scotch is known for its rich and complex flavors, often featuring notes of fruit, spice, and smoke.
