The whisky was also the world’s fastest- growing malt brand, increasing by 69% in value compared with 2010. The Dalmore enjoyed year-on-year value growth in duty free of 95% in 2011.
Whyte & Mackay’s other single malt brand, Isle of Jura, was the channel’s second fastest- growing malt brand, posting value growth of 75%.
In contrast, average value growth for the overall single malt category in 2011 sat at just 8%.
The Dalmore has invested heavily in travel retail in the past two years, building a reputation for launching rare and exclusive whiskies with selected operators.
For instance, in May this year The Dalmore launched the Constellation Collection exclusively with Heathrow airport retailer World Duty Free Group – a 21-bottle collection of rare vintage whiskies valued collectively at £158,000.
Commenting on the results, Whyte & Mackay CEO John Beard said: “The global whisky market is continuing to experience a significant boom in sales and, within the malt category, competition is fierce to capitalise on this growth.
“So it’s testament to the hard work of our staff and the consistent quality of product that both of our malt brands are growing faster than any others out there.”
