Celtic Cask Ocht Déag is a double distilled single malt that was initially matured in a Bourbon cask for 14 years. It was re-casked in a 53-litre Oloroso sherry barrel which was custom made from an old 500-litre solera cask. It was then matured for a further 18 months leaving the whiskey with rich and complex flavour. This superb whiskey is already a staff favourite and will sell out very quickly.
