Following distillation, The Glenlivet XXV is aged for approximately 23 years in traditional oak casks. After its initial maturation, the whisky is double barreled, or finished, in hand-selected, first-fill sherry casks for an additional two years. The sherry casks impart a luxurious and bold aroma of ripe fruits, dark chocolate and creamy vanilla to the whisky. In addition, the sherry casks contribute hints of raisins, dates and figs, which complement the whisky's notes of walnuts, brown sugar and cinnamon. The finish is long opulent, with notes of sherry, red fruits and spices mingled together. Glenlivet XXV earned the Gold Medal at the International Spirits Challenge, the International Wine & Spirits Competition and the The Scotch Whisky Masters Competition. In addition, it earned a score of 93 points from Whisky Advocate, which said that the whisky's "flavors are seamless and elegantly balanced." It also earned a score 95 points from the Beverage Testing Institute.

To craft The Balvenie DoubleWood 17 year old single malt whisky Malt Master David C. Stewart MBE returned to one of his most celebrated achievements- consecutive maturation in two different types of cask, a process often referred to as 'cask finishing'. This technique is at the heart of The Balvenie DoubleWood- it sees the whisky matured first in American oak barrels, which impart soft sweet vanilla notes, before being transferred to European oak sherry casks, where the second cask ageing adds rich spicy flavours and a depth and fullness of flavour. The DoubleWood 17 year old is an elder sibling to DoubleWood 12 year old and shares its honeyed, spicy characteristics, but it is distinctly different, with deeper vanilla notes, hints of green apple, creamy toffee and a striking richness and complexity.
