Halkirk has had two whisky distilleries, Gerston from 1796 to 1885, and Ben Morven (also known as Gerston II) from 1886 to circa 1911. Both were established on the banks of the River Thurso, near Gerston Farm, and both drew water from Calder Burn. The Ben Morven distillery was named for the mountain, the highest point in Caithness.
