The Macallan 30 Year Old Sherry Cask Blue Bottling – No Box – The Macallan 30 Year Old Sherry Cask is a very highly sought-after Macallan that was matured exclusively in Sherry oak casks and bottled in the late 1990s. A sophisticated and scintillating Scotch whisky, this was the final expression of the sherry oak 30 year old before it was discontinued in place of the Fine Oak range.
