The eagerly-awaited second batch of Glenfiddich’s Winter Storm once again sees well-aged whisky from the legendary distillery finished in casks that previously held Canadian icewine (made using grapes harvested while frozen resulting in a powerfully sweet tipple). Released as part of the Glenfiddich Experimental Series, malt master Brian Kinsman believes that only older whiskies can stand up to the intense influence of icewine, which is why Winter Storm is built around 21 year old single malt.
