Blended Scotch Whisky is created by combining one or more single malt Scotch whiskies with one or more single grain Scotch whiskies to produce 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's not uncommon for a well-known house style to rely on dozens of different malt and grain components working together in careful proportion.
Blended Scotch has sometimes been unfairly overlooked 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-crafted blend requires 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 role of the master blender is one of both artistry and discipline: to create a whisky with a recognizable character of its own, and to maintain that character year after year despite the natural variation of the whiskies from which it is composed.
