Glengoyne distillery has stood just north of Glasgow in the Loch Lomond region since 1833. The road separating the distillery from its warehouses also marks the division between the Scottish highlands and Lowlands - thus allowing Glengoyne to uniquely claim they distill in the highlands and age their whiskies in the lowlands. Another way Glengoyne is unique includes their continued use of a high-quality, low yield barley (called Golden Promise - unpeated), coupled with their super slow distillation. Post distillation, Glengoyne treats the liquid they cannot used (called the spent lees) in their own wetlands. The liquid makes its way through a series of twelve pools; each is thick with reed beds which slows the water flow and removes any byproducts that would harm the delicate eco-balance of the local burn. The water is then safe to rejoin the burn, which winds its way into the river and on to Loch Lomond.
