Rock Island 21 years old is a wonderfully mature, island vatted malt. Proudly offered without colouring or chill-filtration. Bottled at 46.8% alcohol strength, rock island 21 years old marries together single malts from Islay, Arran, Orkney & Jura. As a result, it has an amber spirit full of peat smoke, salted caramel, charred oak and subtle spice.
