Dallas Dhu Distillery was founded in 1898 by Alexander Edward of the Sanquhar estate, with construction completed in 1899. Located on the outskirts of Forres in Morayshire, Speyside, the distillery was designed by Charles Doig, one of Scotland's most celebrated distillery architects, whose distinctive pagoda-style roof became an iconic feature of the building. The distillery's name derives from the Gaelic for 'Black Water Valley', a nod to its scenic Highland surroundings. Dallas Dhu produced malt whisky for nearly a century, serving as a key component in the Roderick Dhu blended Scotch whisky. The distillery became part of the DCL (Distillers Company Limited) portfolio, which later became Diageo. Production came to an end in 1983, a casualty of the so-called 'whisky loch' — a period of significant overproduction that led to widespread distillery closures across Scotland. As a result, Dallas Dhu single malt is a rare find, available today only through independent bottlers such as Signatory, offering vintage expressions that provide a fascinating glimpse into a lost era of Speyside distilling. Following its closure, the distillery was preserved by Historic Scotland as a visitor attraction, recognising its architectural and cultural heritage. More recently, reports have emerged of plans to restart whisky production at Dallas Dhu after more than 40 years of silence, reigniting interest in this storied distillery.
