Glenmorangie Signet was created with a marriage of whiskies produced from two unique types of malted barley, a single estate Cadboll variety and malted chocolate barley, which is better known as a basis for craft beers. The Signet was distilled twice through Glenmorangie's copper- pot stills, by a team of 16 distillers known as the "Sixteen Men of Tain". It was subsequently matured in bespoke American virgin oak casks before it was bottled at 46% and receive no chill- filtration.
