Scotland’s Glenfiddich has expanded its single malt portfolio with the launch of Grand Cru whisky.

The William Grant & Sons-owned label notes that its new expression is a 23-year-old single malt whisky finished in cuvée wine casks of France’s Champagne region.

Grand Cru has been matured in American oak and a small number of ex-Sherry casks and finished in first-fill and second-fill French oak casks for four months.

With 40% alcohol by volume (ABV), the expression offers notes of sweet brioche, pear sorbet, white grape and vanilla.

Grand Cru will be the first expression in the company’s new Grand range.

The company intends to add second and third releases to the series by next year. It notes that its Grand range will operate independently, including whiskies such as Glenfiddich IPA Cask, XX, Winter Storm and Fire and Cane.

Glenfiddich malt master Brian Kinsman said: “We experimented with the maturation time and hand-selected the right balance of 23-year-old Glenfiddich casks out of our unique collection of old age malts.”

Grand Cru will initially be available as a Harrods-only exclusive for two weeks. It will be launched later at other speciality retailers in the UK for £220.

The product will also be available in the US, Singapore, South Africa, Taiwan, travel retail and on the company website.

In July, Glenfiddich launched a limited-edition, 30-year-old single malt to celebrate the 50th anniversary of its visitor centre in Scotland.

Glenfiddich Rare Collection Cask No. 20050 will be available for £1,600 ($2,000). A total of only 200 bottles were released.
