William Grant and Sons has bought Gibson’s Finest, the Canadian whisky brand owned by Diageo.

Gibson’s, which will continue to be distilled and bottled in Quebec, is the number three premium and deluxe Canadian whisky in the country, with a 17% market share.

Heather Graham, William Grant & Sons’ business development director, said: "The acquisition of Gibson’s Finest adds a cherished Canadian whisky brand to our award-winning portfolio of Scotch whiskies and strengthens our position in the important Canadian spirits marketplace.

"The purchase is testament to the commitment to expand our business both through the organic growth of our Glenfiddich, Grant’s and The Balvenie brands and through the development of new business streams."
