Tasted in a lineup of these Craigellachie OBs:
13yo (82 pts.), 17yo (84), 19yo (86), 23yo (89), 23yo Exceptional Cask bot. 2017 @ 46% (87), 19yo Exceptional Cask #128 55,4% (91) and 21yo Exceptional Cask #5009 @ 55,7% (90).
More of that distillate sulfur than in the 13yo, so some meaty or cordite notes. Also more fudge, some soft oak, faint grass, cloth, and butter, and that tropical fruit note that comes with the distillate.
Feels more mature and rounded on the tongue than then 13yo. Weightier too. I really like these subtle mature oak touches. There is a bit of booziness to it, but just a few drops of water dispel that if necessary. There is a wisp of peat smoke here as well. I get a drying feeling in my gums when I keep it in my mouth for a while.
The finish is dry, more so than expected. I think it falters a bit here, and would earn 85 points without this little glitch. Some grass and pineapples.
