The Caledonian Brewing Company has bought the small, award-winning Scottish brewery Harviestoun for an undisclosed fee.
Caledonian, which produces Deuchars IPA from its base in Edinburgh, has pledged to expand operations at the Harviestoun brewery in Alva, Stirlingshire.
Harviestoun's Bitter and Twisted won CAMRA's Supreme Champion Beer of Britain in 2003 and it was also a Champion Beer at the International Brewing Awards 2004.
Stephen Crawley, Managing Director of the Caledonian Brewing Company, said: "The Harviestoun portfolio fits perfectly into our range. We will continue to brew Harviestoun's beers with the pride that they have always demonstrated."
Harviestoun was founded 20 years ago by Ken Brooker who said: "I am delighted that Caledonian will be taking over the brewery.
"They know the industry inside out and are passionately committed to producing quality cask conditioned beer.
"I couldn't have wished for a better scenario.
"I have enjoyed every moment of creating and developing a brewery which basically started off as a hobby and I'm pleased to leave it in Caledonian's professional and capable hands."
