Just 276 packs have been released worldwide. Each is accompanied by a hand-signed certificate from distillery manager Malcolm Waring.

The 21-year-old expression, named World Whisky of the Year in 2012 by Jim Murray’s Whisky Bible, is a “full-bodied” whisky with hints of apple and pear.

The “rich and sweet” palate has “subtle light fruity notes and touches of honey and vanilla, followed by a dry finish”.

Old Pulteney 1989 pays homage to the brand’s maritime heritage.

The whisky is matured in hand-selected American oak ex-Bourbon barrels, which previously held a peated malt.

On the nose, there are hints of spice, green apples and wood smoke. The palate is “rich and dark with subtle spices” and has a “long-lasting” finish.

Vicki Wright, Old Pulteney brand manager, said: “It doesn’t get better than this. The twin pack speaks for itself, with each expression winning a top-respected industry award for their exceptional quality. We are incredibly proud of these exquisite bottles and hope other passionate whisky drinkers share our enthusiasm about this special collector’s release.”
