A blended whisky from the 1950s which features a spring-cap.

The whisky was produced and bottled by Benmore Distillers Ltd of Glasgow and is named after the Scottish mountain which stands 1,174 m (3,852 ft) tall.

The Benmore blending company foundered in the late 1980s. They originally had a distillery in Campbeltown and would go on to also own Lochindaal on Islay and Dallas Dhu in Speyside by the 1920s. The Benmore blend was also created around this time and included malts from all three distilleries, though only Dallas Dhu was ever mentioned on the label.

In its time a key component of the Roderick Dhu blended Scotch, Dallas Dhu is a rarely seen single malt. As with much of the DCL (now Diageo) portfolio, the distillery was deemed surplus to requirements during the market downturn of the 1980s, and closed in 1983. It is now run as a distillery museum by Historic Environment Scotland. Very few official bottlings exist, and it is incredibly sought after when rare independent bottlings appear.
