Springbank 18 Year Single Malt Scotch Whisky
After malting and lightly peating the barley (using locally cut peat), the distillers at Springbank mill and mash it in cast-iron mash tuns that are nearly a century old. The pure spring water used during the mashing process is sourced from Crosshill Loch, which in turn is fed by springs seeping from the northern slopes of 1,100-foot tall Beinn Ghuilean. After mashing the grains, the wash is slowly fermented over the course of 70 hours — one of the longest fermentation processes in Scotland — before being distilled. Because some of the wash is distilled twice and some is distilled three times, Springbank Whisky is said to be distilled two and a half times.
Following distillation, Springbank 18 Year Old Single Malt Scotch Whisky is matured in a combination of casks that were previously used to mature sherry (80%) and casks that were previously used to mature bourbon (20%). During maturation, the perennial gulf stream adds a slight hint of saltiness to the whisky, which complements its notes of rich fruits and caramel.
