Whisky Advocate finally lays out something I've wondered about: which single malts go into which blends?
“Cardhu’s at the heart of Johnnie Walker,” says Emma Walker, one of 12 master blenders that work on Johnnie Walker. “Cardhu was always a blender’s favorite,” she adds. “It was essential to Johnnie Walker. They always created high-quality spirit and it became a partnership even before Cardhu joined the Johnnie Walker family.”
Owned by Diageo, Cardhu Distillery is just one of the global corporation’s 29 whisky-producing distilleries in Scotland alone. This gives the Johnnie Walker blending team a vast library of stocks to work with.
For fans of single malt scotch, being able to identify the single malts that make up a blend is a fun endeavor that is sure to bring new appreciation for the craft of blending.
That's true, and in some cases it works inductively. Like, where does 90% of Caol Ila's output wind up?
