First bottled in 1968 (what I wouldn't give to get me hands on some of that!) Glenfarclas 105 is an original NAS that is bottled at high strength and well worth your attention. While the casks used are believed to be in the 8-10 year old age range the quality of sherry casks used is unsurpassed in the industry.
Glenfarclas 105, 60% alc., $85-90
N: Xmas cake coming and going (raisins, dark cherries, ginger, nutmeg, and orange zest), also clean rubber notes (like the inside of a dishwashing glove) and cold buttered toast (wholewheat toast given all the malty notes)
P: Huge and explosive, the sweet sherry dominates (more rubber notes crisscross the palate), the wood dries out the palate quite nicely while the orange zest from the nose has become chocolate covered orange peels
F: Long and warming, the alcohol resonates all the way down the throat and into the chest while the bitter wood sits in harmony with the sweet sherry
In conclusion: A benchmark cask strength whisky that should feature in everyone's collection. A personal favorite of mine for almost twenty years.
