The Tamdhu story starts under the warming Spanish sun. In 1898 the founders secured their first precious shipment of sherry casks from the finest bodegas in Spain. Now over 100 years later, Tamdhu matures its whisky exclusively in the finest Oloroso sherry casks. Although the casks are exceptionally rare and expensive, they wouldn't change their methods, as they think it's the only way to create the very best single malt whisky.
