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.

Glenfarclas 40 YO Single Malt Scotch Whisky is matured for a minimum of four decades in used oak casks. As a result, the single malt has an aroma of chewy leather, walnuts and chocolate covered raisins, which gives way to lush notes of cocoa beans, woody tannins, dates and dried figs. The lingering finish, which is never too oaky, has hints of toffee and caramel. Glenfarclas 40 Year Old Single Malt Scotch Whisky earned a score of 95 points from Whisky Advocate, which also named it the Editor's Choice and called it "a very good value for its age."
