Celtic Cask Seacht Déag is a double distilled single malt that was initially matured in a Bourbon cask for 14 years. It was re-casked into a 53 litre Pedro Ximenez sherry barrel which was custom made from an old 500 litre solera cask. It was then matured for a further 18 months. The sweet Pedro Ximenez sherry barrel has given the whiskey some delicious chocolate and spiced fruit notes. This is an amazingly rich and full-flavoured whiskey and it is sure to sell very quickly.
