Mortlach steals the show at The Twelve by Casks of Distinction

During The Twelve by Casks of Distinction, there came a moment unlike any other. This is the first time such an aged Mortlach whisky has been part of this special event. We're talking about a 41-year-old single malt that was distilled in 1984 at Mortlach Distillery.

Dr. Craig Wilson, Master Blender at Diageo, calls it "a piece of living distillery history" and commends its complex expression.

‘It’s a bold and complex expression that perfectly captures the essence of Mortlach, and, in my opinion, this superb cask has more than earned its name.’

- Dr. Craig Wilson
