Triple maturation is the secret behind the award-winning taste of Whyte & Mackay. Stage 1: The finest malt & grain whiskies, matured for many years, are carefully selected by our Master Blender. Stage 2: Next, they are each combined in sherry casks and matured once again. Stage 3: Finally the aged malts & grains are blended and returned to cask one final time to attain a perfect harmony of flavours. This dedication to the art of blending creates an extra smooth and richer tasting whisky.
