Scottish craft brewer Innis & Gunn will accelerate plans to expand its Beer Kitchen casual dining concept into England after raising £1 million in 72 hours via crowdfunding.

The two Beer Kitchens already open in Edinburgh and Dundee will be joined by another in St Andrews in the next couple of weeks, with Glasgow to follow in the spring.

Dougal Sharp (pictured), the company’s founder and master brewer, said the sale of 2% of share capital on Crowdcube was designed to fund Scottish expansion – but with £1.5 million raised from more than 1,000 investors by mid-November, sites in England and in Toronto were now being sought for openings in the next year or so.

“The whole craft beer scene is exploding internationally,” said Sharp, who launched Edinburgh-based Innis & Gunn in 2003.

Beer Kitchens use appropriate Innis & Gunn beers in their cooking – duck breast marinated in “rum finish” or lamb shank braised in “Irish whiskey finish” – with beer pairings recommended to diners. Wine is on offer as well as craft beers from other breweries, and the venues also function as bars for customers who just want a drink.

Investing via Crowdcube remains open until the end of November.
