Translating as "Rare Cask" in Gaelic, Casg Annamh is created from a limited number of carefully selected casks. These Spanish oak Oloroso Sherry casks/butts have a significant influence on the non-chill filtered liquid and perfectly complement Aberlour's distillate flavour, bringing sweet and rich notes. Casg Annamh is a distinctively rich Single Malt providing adventurous malt lovers with the ideal introduction to Sherry cask matured whiskies.

Westland Sherry is where the old and new world meet. The use of ex-sherry having long been a part of the Scottish tradition, its decadent, fruit-laden palate serves as a perfect balance of Westland's signature grain-house style. Westland's house style single malt is made from five exceptional roasted and kilned barley malts the base of which is pale malt grown right in the state of Washington. Drawing inspiration from the rich brewing culture of the Pacific Northwest, several specialty malts (Washington Select Pale Malt, Munich Malt, Extra Special Malt, Pale Chocolate Malt and Brown Malt) are then added before the resulting mash is fermented with a Belgian brewer's yeast for 144 hours. Then, the whiskey is distilled through Westland's copper-pot stills.
