Whisky Resource Note

The Kilkerran Official Website has very limited and poorly updated information about their bottle releases.
The homepage was referencing a previous release of the 8 Year Old Cask Strength.

From Master of Malt

Highly sought-after single malt from Campbeltown's Glengyle distillery, it's a cask strength edition of Kilkerran single malt, brimming with satisfying layers of sherry and smoke. Weighing in at a bold 57.5% ABV, this one spent its eight years maturing in a sherry cask, ensuring a wealth of dried fruit and cakey spice to complement its peaty core

From The Whisky Exchange

Released in early 2023, this eight-year-old Kilkerran single malt was matured exclusively in ex-sherry casks, before being bottled at cask strength. Aromas of toasted marshmallows, peat smoke, dark chocolate, clove and smoked ham fill the nose, complemented by notes of sea salt, candied apples, toffee, sweet peat and burnt candies throughout the palate and lingering in the finish.
