This limited-edition release is part of The Glasgow Distillery's Small Batch Series, an ongoing collection of bottlings that highlight the versatility of whisky produced at this modern urban distillery. The Small Batch Series showcases the distillery's three whisky-making styles—peated, unpeated, and triple-distilled single malts—exploring a variety of new and exciting cask maturations.

The Glasgow 1770 Madeira Cask Finish is a six-year-old whisky from a single finishing cask. It was initially aged in a virgin American oak cask from Kelvin Cooperage, Kentucky, followed by a finishing period of one year and eleven months in a cask that previously held Madeira wine.
