The Bushmills Causeway collection is a series of exclusive, limited edition single malts crafted to showcase the best of Bushmills Single Malt Irish whiskey. The team have sourced some very special casks and choose to further mature their ex-bourbon and ex-oloroso matured whiskeys for a considerable amount of time in these special casks. The period of time would suggest more a secondary maturation than merely a finish. The releases are bottled at cask strength.
This release is from 10 year old ex-bourbon and ex-oloroso whiskeys, married and recasked for a further 15 years in marsala casks, sourced from the island of Sicily. The release was bottled at 57.8% abv. Non-chill filtered, no added colouring.
