Blended Scotch Whisky is made by combining one or more single malt Scotch whiskies with one or more single grain Scotch whiskies to create a balanced and consistent whole. Every component whisky must comply with the legal requirements for Scotch whisky production, which means that each must have been distilled and matured in Scotland, matured in oak casks for at least three years, and bottled at a minimum strength of 40% ABV. Many blends are built from a large number of individual whiskies, and it is not unusual for a well-known house style to depend on dozens of different malt and grain components working together in careful proportion.
Blended Scotch has sometimes been unfairly dismissed by enthusiasts who focus only on single malts, but the category remains central to the history, character and global success of Scotch whisky. A well-made blend demands not only excellent component whiskies, but also a high degree of precision in assembling them so that the final result is harmonious, distinctive and consistent over time. The task of the master blender is one of both artistry and discipline: to create a whisky with a recognisable character of its own, and to preserve that character year after year despite the natural variation of the whiskies from which it is composed.
