Tamdhu is one of the few remaining distilleries with onsite maltings and the only one still using a Saladin box, Tamdhu produces all of its own malt as well as enough to supply other distilleries in the Edrington group, notably the Glenrothes distillery. Tamdhu lies on the banks of the mighty River Spey, not far from Knockando. The Knockando distillery's ancient railway station has since been converted into the Tamdhu visitor centre. Tamdhu has changed hands a number of times over the years. It was previously owned by Edrington Group who, with William Grant in 1999, acquired the distillery from Highland Distillers who had owned the distillery for over a decade. In 2010, the distillery was mothballed and sold to Ian Macleod Distillers the following year. Throughout 2012, Tamdhu was re-commissioned, with production starting once again. Tamdhu released a new single malt in 2013 - the handsome Tamdhu 10 Year Old, which was followed by the Tamdhu Batch Strength series and the hugely impressive Tamdhu 50 Year Old.
