Garnheath Single Grain Whisky Lowland-based distillery Garnheath began producing malt and grain whisky in 1965. It was owned by Inver House Distillers, who actually built the distillery in order to secure future liquid for its blended Scotch, Inver House Rare. In 1983 Inver House sold its Bladnoch distillery to Arthur Bell & Sons after only a decade of ownership. Garnheath was then closed and demolished in 1986, and only Garnheath’s warehousing, blending and office facilities continue to function as Inver House’s headquarters in Airdrie. Garnheath was never officially bottled as a single grain, though a small handful of independent bottlings exist.
