The Bruichladdich Black Art 8.1 continues the series' tradition of shrouding its expressions in a veil of mystery where the exact casks used to age the spirit are only known to the head distiller. This is Hannett's 4th release and 8th overall. It was distilled in 1994 and bottled in 2020, making it a 26-year-old single malt that was matured entirely on Islay. It is, of course, non-chill filtered and has no added coloring. This non-peated expression has the oak highlighting the delicate citrusy and fruity notes and is limited to 12,000 individually-numbered bottles.

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.
