This Dewar’s Double Double expression is aged for a minimum of 21 years in our four-stage ageing process. The final step involves finishing the whisky for six months in American Oak casks that have been evenly stone toasted to a Level 1 toasting intensity with Icelandic Magma stones. This gentle toasting for two hours between 160ºC – 240ºC has aided the development of succulent notes of vanilla, a hint of coconut oil and ripe summer fruits.
