This expression of the famous whisky, from the remote island of Islay in the Western Isles of Scotland, has enjoyed a triple maturation in 3 types of cask. Just as with the standard Quarter Cask expression, the first maturation is in American oak, ex-Bourbon Barrels. They then select the most suitable of these barrels, containing a range of different aged spirit and transfer into small 19th Century style Quarter Casks for a second maturation. The final maturation is in specially selected, large European oak, Oloroso Sherry Casks. It is bottled at 48% ABV and is non-chill filtered for a depth of taste and texture.
