The Winter Storm is the third bottling in The Experimental Series from Glenfiddich. The whisky has been created by Brian Kinsman, the brand's Malt Master, and uniquely uses Canadian ice wine casks made from French oak for a short finishing period. These have previously matured ice wine, made from grapes frozen on the vine and picked at night, produced at the Peller Estate winery in Niagra. Following a period of experimentation, Kinsman discovered that older whiskies reacted best with the casks. Therefore, the Winter Storm is a 21 years old expression with a six month finish in the ex-ice wine casks.
