Dewar’s is called “The Ancestor” in honor of our founder, John Dewar, this impeccable blend is the result of a time-honored process. After we blend our DEWAR’S 12 Blended Scotch Whisky, we return it to vintage oak casks, allowing the whiskies to age together and harmonize to perfection. This extra step makes DEWAR’S 12 Blended Scotch Whisky an even smoother blend with a long, lingering finish.
