We have replicated this freedom with The Glenlivet Founder’s Reserve, selecting whisky from a variety of traditional aged oak casks. Then, to lend a modern twist to the flavor of the expression, our makers marry together a selection of the aged oak casks and American first-fill oak casks. American first-fill oak casks are those that have never before been used to mature whisky. The selective use of these casks provides a smooth, creamy sweetness that mingles harmoniously with the delicate flavors and complex fruity tones already present in the whisky.
