Glenrothes 29 Years Old 1989 Cask #DL 14056 (XOP)

Douglas Laing's XOP (Xtra Old Particular) range presents the firm's deepest aged stocks, sitting above the regular Old Particular range as the premium tier for casks of exceptional age or character. The Black Series uses dedicated dark labelling to distinguish these releases. This Glenrothes 29 Years Old, distilled in 1989 and bottled in 2020 from cask DL 14056 at 47.5%, runs to 478 bottles released into the German market.

Twenty nine years in a refill bourbon cask produces a profile fundamentally led by distillery character. The cask's first fill activity exhausted under previous tenancy, the wood contributes through accumulated secondary chemistry: lignin's slow breakdown delivers syringaldehyde and vanillin at attenuated levels, lactones produce coconut and creamy oak through cumulative contact, and ellagitannins build structure gradually. The 47.5% strength reflects long evaporation in higher humidity warehousing across nearly three decades.

On the nose, cooked mash signals the spirit's brewhouse character beneath the cask layer, with citric lift, cooked and dried fruit threading through. A chocolate undertone sits beneath, with a fragrant lift signalling preserved ester chemistry. The palate runs honeyed and gentle through fresh apple, lemon curd and a clean vanilla pod note, the 47.5% strength delivering preserved acidity and accumulated character with minimal cask interference. The finish is long and softly drying, the cask leaving the spirit's deep maturation clearly framed.
