Produced in small batches, Glenfiddich 18 Year Old combines a touch of sweetness from the Spanish Oloroso wood, with oakiness drawn from the traditional American casks. Through marrying in wooden tuns (vast vats), the rich, mellow flavours to come together, creating an exceptionally smooth single malt Scotch whisky with notes of spiced apple and robust oak. Each batch is of a unique and of exceptional quality. Their master craftsmen have created a complex, mellow single malt Scotch whisky from years of patient maturation in casks of the finest Oloroso sherry and American bourbon. It is secreted away in their traditional warehouse, where the cool, thick stone walls and low ceilings mature the whisky to perfection. Years later what emerges is a Glenfiddich Ancient Reserve with an elegant nose, faintly sweet, scented with apple and wood. It is robust and full-bodied, yet remarkably soft, rounded and long lasting.
