The initial maturation in American oak, before finishing in French oak ex-Cognac casks, adds a wealth of complexity to Octomore 15.2. Demonstrating the finesse quality oak has on the final spirit, the 15.2 is simultaneously powerful yet elegant with the delicate floral character of the whisky coming to the fore. The softness of the oak is unmissable on the palate, working with the spirit's mineral quality and dry peat smoke beautifully.
