Good distilleries never die; they just get mothballed until rediscovered and reopened for an appreciative newer generation. That certainly is the case with this sherry-barrel-aged Speyside whisky, a key component in The Famous Grouse, J&B, and Cutty Sark blends, but equally coveted for its smooth, sophisticated single malts. Founded in 1897 and rebuilt in the 1970s, Tamdhu sadly was shuttered in 2010 until resurrected by Ian Macleod Distillers in 2012. To commemorate the distillery’s 120th anniversary this year, 100 engraved silver-capped crystal decanters have been filled with a 50-year-old spirit from cask number 4678, a first-fill European-oak sherry butt that was distilled on November 2, 1963, and bottled in March 2017. The oldest single malt ever released by Tamdhu, this deep mahogany whisky is bursting with cloves, licorice, and baked apples, while cocoa, ginger, and walnuts linger in its long finish ($20,000).
