I have no idea how good a recreation this is, or whether its what Shackleton would have tasted. I do know that this is stunning, a world class 90 plus whisky. If anyone ever wants to understand the sophisticated nature of great blending this is it. Would I buy it? Without a doubt. & open it & drink every last drop.
