Explorer Tour
This one and a half hour visit begins with a short film recounting our 5 generations of family ownership.
It is followed by an on-foot tour of our Distillery with the opportunity to discover how the worlds most awarded whiskies are created, by craftsmen with generations of understanding. The tour inlcudes a visit to the Still House where you can see how our skilled Stillmen capture the sweetest part of our distillate from our unusually sized copper stills.
You will also visit two of our warehouses where you will explore the generations of gently maturing casks and learn how we achieve depth and consistency of flavour throughout our range of exceptional whiskies.
The special conclusion to this visit is a tutored nosing and tasting of four of our single malts Glenfiddich 12, 14, 15 and 18 Year Old.
