Historically used for blending, Tamdhu flies under the radar of many scotch aficionados. But this underappreciated Speyside whisky compares well with more famous sherry bombs by offering a sweet, savory, slightly funky depth. At first sniff, Tamdhu seems like it might knock you out with one blow—but this gentle giant is a lover, not a fighter. Viscous and meaty, this cask-strength stunner reveals dried fruit, dark chocolate ganache, ginger spice, and saline minerality, thundering softly into a long finish. Ian Macleod Distillers revived Tamdhu, and their pledge to bring Rosebank back to life excites us to rediscover more top-quality whisky with a distinct identity. —Susannah Skiver Barton
