In 1897, a group of entrepreneurs pooled resources to create the a fine whisky, raising the equivalent of £20 million to achieve their goal. They enlisted the help of Charles C Doig ESQ, a top distillery architect and engineer, secured a perfect location by the River Spey, and selected ideal sherry casks from Spain. In 1949, they introduced Saladin boxes to modernise the barley turning process. Tamdhu expanded to meet the growing demand for whisky in the 1970s by adding four stills.
However, in 2010, the distillery was forced to shut down. In 2012, Ian Macleod Distillers reopened it, restoring the distillery to its former glory with the same dedication to 100% sherry oak cask maturation. In 2018, the Tamdhu family released the Tamdhu 12 year old Single Malt, followed by the 15 Year Old Single Malt, which continues their commitment to sherry cask oak maturation. They also introduced the 18 Year Old Single Malt to commemorate 125 years of whisky excellence.
