Renowned for its double aging process, the Double Double range from Dewar's takes things to an entirely new level of whisky craftsmanship with a 'quadruple aging' or 'double-double' aging process. Dewar's Double Double 21 Year Old Mizunara Oak Finish brings together the distilling traditions of Japan and Scotland, creating a rare blend that captures the essence of two cultures. Created by Master Blender Stephanie Macleod, this coveted blended Scotch whisky features a blend of double-aged malt and grain whisky matured for 21 years and then married in an oak cask for a secondary double aging period before finally being finished in hand-selected, extremely rare Japanese Mizunara oak casks. Bottled at 92-proof, Dewar's Double Double 21 Year Old Mizunara Finish was ranked 7th in Whisky Advocate's Top 20 Whiskies of 2023 with a rating of 95.
