Bushmills 30 Year Old 1991 (cask 100068) Madeira Cask - The Causeway Collection 70cl Whiskey

An astonishing release from Bushmills here, from the second edition of the annual Causeway Collection. This Irish single malt whiskey was matured for over 13 years in a combination of oloroso sherry butts and bourbon barrels, before going through over 15 years ageing in first-fill Madeira wine casks. Just 738 bottles were released at a cask strength 50.2% ABV without chill filtration or artificial colouring.
