The Balvenie Madeira Cask 15 Year Old is a lively and summery single malt finished in casks previously held sweet Madeira wine. In historic times, ships set sail filled with casks of Madeira wine around the New World. Throughout their journey, casks were exposed to the heat of the sun, naturally sweetening the wine it held. Malt Master David C. Stewart has enjoyed times exploring the Madeira region and wines they produce, inspiring this experimentation of the cask type for finishing.
