SCOTTISH craft brewer Innis & Gunn has launched a limited edition beer to celebrate 15 years since its inception.

The exclusive drink also marks the end of a successful year for the firm, who saw turnover grow by 22% and gross profit rise by 19.1% to £10.1 million.

Dougal Gunn Sharp, Innis & Gunn Founder and master brewer said: “Achieving our 14th year of consecutive double digit volume growth is down to the hard graft of the team, our commitment to innovation and the quality of our beers.

“In the UK Innis & Gunn Lager has continued its stellar growth, having doubled in size in the last two years. Our ambition is for it to become the UK’s number one craft lager, an achievement we have already reached in Scotland.”

The special 7.4% abv beer, named “15”, is a barrel-aged double IPA that has been matured in 15-year-old whisky barrels from the Highlands of Scotland. It is available to buy from October 3 from here.
