Whisky Johnnie Walker Blue Label Ghost and Rare Port Dundas. The fifth release of Johnnie Walker's limited-edition Ghost and Rare series celebrates Glasgow's famous Port Dundas grain distillery, that closed its doors and sired down its stills in 2010. Known for its distinctive sweet, fragrant character, Port Dundas was not only a blending powerhouse but also one of the world's most-famous grain whisky distillery, and Johnnie Walker master blender Dr Emma Walker has hand-picked whiskies that will complement and show off this ghost distillery's character. The creamy, woody notes of Port Dundas have been complemented by softly smoky, vanilla-forward whisky from ghost distillery Cambus, original stocks from Brora and fruity whiskies from five iconic distilleries.
