DEWAR'S 12 Years Old 6/LT 80P DEWAR'S 12 is a perfectly balanced marriage of carefully selected 12 year old malt and grain Scotch whiskies, created by DEWAR'S sixth Master Blender, Tom Aitken. This perfectly balanced taste is achieved through the marrying process, originally pioneered by our first Master Blender, A J Cameron. Only malt and grain whiskies of the highest quality are used to create this rich, fruity and delightfully mellow whisky.
