Sales director David John said: "The individuality and breadth of the range gives us a great opportunity to develop sales within this dynamic sector.
"The use of traditional methods and a non-interventionist approach give these whiskies a really strong selling point ."
The distillery is based in the village of Lochranza on the Isle of Arran, which lies off the west coast of Scotland. It was opened in 1995 and remains the only distillery on the island.
