100 proof is British measurement from the days when alcohol was tested by pouring in gunpowder and seeing whether it would still ignite. The threshold sat at 57.1%, and that figure is still a marker.
The Expert's Description
Aultmore 17 Years Old Signatory 100 Proof Exceptional Cask Edition #1 is a Single Speyside Malt Scotch Whisky matured in a 1st fill Oloroso sherry cask and bottled at 57.1%. It is neither chill filtered nor coloured.
Signatory’s 100 Proof range is deliberately bottled at exactly 57.1%, the historic British proof point. It is not cask strength but a fixed, high strength, and the house selects casks whose profile can carry it.
Aultmore’s fresh, grassy Speyside style has been laid into an active sherry cask here, which gives a markedly different expression from the bourbon matured bottlings. The distillery was built in 1896, and almost all production otherwise goes into Dewar’s White Label.
Tasting Notes
Nose
Dark and sweet. Raisins, orange peel and walnut first, then dark chocolate and a dry spiced oak note. The alcohol is evident but carried by the sherry.
Palate
Powerful and full. Dried fruit and sherry sweetness open, then nuts, cinnamon and black pepper arrive. At 57.1% there is real weight, and Aultmore’s freshness peeks through beneath the sherry.
Finish
Long and dry. Dark fruit, nuts and spiced oak that hold on for a long time.

Did You Know?
The term proof comes from a British method of testing spirits: it was mixed with gunpowder and an attempt made to ignite the mixture. If it burned, the spirit was proved. The threshold corresponds to 57.1% alcohol, and that figure is still used as a deliberate choice of bottling strength.
