The company’s net profits grew by nearly 60% in 2013, it reported in its latest end-of-year accounts.
Growth came particularly from exports, which grew 26%. The distillery’s biggest market is France, and it has also made gains in the US, Taiwan, Belgium and the UK.
Managing director Euan Mitchell said: “It is really pleasing to see that our approach and hard work is delivering results. We are something of an overnight success, nearly 20 years in the making.
“We are again performing ahead of the market, which saw exports rise by 5% whereas we increased this market by 26% last year. Our portfolio of single malts is varied and interesting, which is reflected in the ongoing interest in the Arran Malts around the world.”
Isle of Arran Distillers has invested in a new warehouse due to open at the end of this year, giving it the capacity to store an extra 12,000 casks. It plans to install two more pot stills by 2016, effectively doubling its production capacity, and plans to upgrade its visitor centre, which received 60,000 guests last year, in early 2015.
Mitchell said: “This investment in the distillery is a mark of our confidence that we can continue building sales around the world for many years to come. We have achieved a lot in recent years though the potential to grow is enormous and we need to lay down the stocks now to ensure we can meet the anticipated demand.”
