William Grant & Sons has been given the green light to acquire two whisky brands from Edrington Group.

The Competition and Markets Authority has allowed the owner of Glenfiddich to add The Famous Grouse and Naked Malt whisky to its portfolio.

William Grant & Sonds acquired the brands from The 1887 Company, a subsidiary of Edrington, last September.

“This is an important moment for William Grant & Sons,” said William Grant & Sons CEO, Søren Hagh. “The acquisition of The Famous Grouse, when completed, will further demonstrate our significant commitment to building category momentum in scotch whisky in the UK and in our markets globally.”

Edrington is expected to exit blended scotch entirely in order to focus on its premium single malts, The Macallan, The Glenrothes and Highland Park.

Sales of The Famous Grouse fell 2.2% last year, on volumes down 8.5%, though the brand remains the largest scotch whisky in the UK off-trade, with sales of £206.8m.
