More than 300 whiskies were in the running for the accolade but The Macallan single malt outshone the rest as store manager votes were combined with sales data to crown a winner.
The Macallan Amber retails at £59.99 and was praised for its vivid colour and strong use of sherry casks.
Ken Grier, director of malts at brand owner Edrington, said: “This recognition is testimony both to this innovative approach to whisky making of taking colour as the basis for shaping these whiskies, and to the long experience of our whisky maker Bob Dalgarno.
"As some 60% of the aroma and flavour of The Macallan derives from the oak maturation casks, Amber truly demonstrates the critical role of our exceptional casks.”
Andrew Torrance, managing director at The Whisky Shop, added: “Although it was only launched earlier this year, The Macallan Amber has already established itself as one of our leading single malts.
“Our Whisky of the Year is voted for by our customers as well as our knowledgeable store managers, which underlines the impact of this new addition to The Macallan range and The Macallan Amber is a highly deserving winner of our Whisky of the Year 2013.”
Previous winners of the award, which is now in its seventh year, are Jura Superstition, Dalmore 12 year old, Laphroaig Quarter Cask, Auchentoshan 12 year old, Bowmore 12 year old and Bunnahabhain 12 year old.
