Cider

Cider is an alcoholic beverage made using the fermented juice of apples. The earliest documented record of it dates all the way back to 55 BC when Julius Caesar's retreating troops brought the idea back to Rome after witnessing the native Celts fermenting crabapples in Britain. Today the United Kingdom is the largest consumer of cider, however it is third behind France and Spain in terms of production.

The use of cask ageing in cider is not traditional and as such, ex-cider casks in whisky maturation are not common either. In fact, their use is not currently approved by the Scotch Whisky Association at all. However, Glen Moray did release a limited edition single malt in 2018 called the Cider Cask Project, which skirted the ruling by reusing casks that had previously aged their single malt prior to being provided to Thistly Cross to make its Whisky Cask Cider. Tullamore D.E.W. were the original pioneers of the practice however, releasing the first Irish whiskey aged in cider casks in 2015, and only occasional examples of other whiskies have surfaced in the years since, keeping it as something of a novelty for the industry.
