In the giraffe-high stills at Glenmorangie, it begins soft and fruity, then gets darker and deeper as it is aged for 14 years in bourbon casks and port casks from Portugal. The finished whisky is a thicket of voluptuous flavour combinations. Walnut and black pepper. Mandarin orange and melted marshmallow. Dark chocolate bar and peppermint. And, like stepping into a chocolate-minty-orange unknown, the journey is as delicious as the destination.
