Glengoyne Distillery is a distillery founded in 1833 in Dumgoyne, north of Glasgow, Scotland. The distillery has been in continuous operation producing Highland single malt whisky for over 175 years. Glengoyne is unique in producing Highland single malt whisky matured in the Lowlands. This is because the distillery itself sits upon the Highland Line, the division between the Highlands and Lowlands of Scotland which splits the distillery in two. Unlike many malt whisky distilleries, Glengoyne does not use peat smoke to dry their barley, but instead uses warm air. Glengoyne, along with The Macallan, is one of only two distilleries remaining today that uses Golden Promise barley which is low in yield but high in quality. The distillery's water supply comes from the Glengoyne Burn which flows from the nearby Dumgoyne hill into the distillery grounds.
