Glenfiddich Grand Cru 23 Year is the first in the Grand range released by the brand. The single malt ages for 23 years in a mix of American and European oak before it finishes for up to six months in selected cuvée wine casks. These French oak wine casks formerly held fermenting wine which would ultimately become Champagne. It is available exclusively at Harrods in the UK for the first two weeks of September 2019 before being released to other markets including the US and global travel retail.
