Tamdhu sits on the banks of the Spey at Knockando, founded in 1897 during the great Speyside boom and built to supply blends — for most of its long life it has been an anonymous filling for the trade rather than a name on a bottle. Its modern existence as a single malt brand really begins in 2011, when Ian Macleod Distillers bought the silent distillery from Edrington and reopened it with a clear identity: sherry-cask Speyside, almost exclusively.
The 18 Year Old, introduced in 2019, is the oldest core expression and a deliberate statement of that house style. Matured entirely in first-fill Oloroso sherry casks — both European and American oak — and bottled at 46.8% without chill-filtration, it represents what Tamdhu's master blender Sandy McIntyre and his team consider the upper register of their cask programme.
What strikes you is the restraint. Eighteen years of first-fill sherry can easily turn into a tannin-heavy slog, but Tamdhu's spirit — relatively light and grassy when new — carries the wood without buckling. There is the expected Christmas-cake density, the polished furniture and the orange peel, but the underlying distillate still pokes through in the finish as a clean cereal note.
It is an unfashionably traditional dram, the sort of thing that would not have looked out of place on a Victorian sideboard, and that, given Tamdhu's 19th-century origins, feels rather appropriate.
