Pusser's Rum Gunpowder Proof

Pusser's Rum Gunpowder Proof. Pusser's Rum Ltd., Guyana & Trinidad — the overproof expression of the original Royal Navy Admiralty blend, produced at original Admiralty strength in accordance with the blending recipe last used before the Royal Navy discontinued its daily tot on 31 July 1970, delivering a full-bodied rum with pungent molasses, treacle, toffee, honey, and vanilla alongside oak, cinnamon, nutmeg, and ginger with a long, smooth, mellow finish despite its elevated proof.

The name "Gunpowder Proof" comes from the Royal Navy's pre-hydrometer method of testing rum strength: the ship's Pusser (Purser) would pour a small amount of the sailors' daily rum ration onto a measure of gunpowder and attempt to ignite it. If the mixture burned, the rum was "at proof" — strong enough for the gunpowder to ignite. If it didn't, the rum had been watered down, and the Pusser responsible might find himself thrown overboard. The test corresponded to approximately 57% ABV (100 proof on the old British system), which is the strength of the Gunpowder Proof expression today.

Pusser's received permission in 1979 to produce the original Admiralty blend commercially after the 1970 discontinuation of the naval rum ration. The Guyanese Demerara component brings the characteristic heavy pot still aromatics — molasses, treacle, marmalade, tobacco — while the Trinidadian column still rum provides refinement and balance. At Gunpowder Proof strength, the full depth of the Admiralty blend is expressed at its most complete.

Tasting Notes

• Color: Clear, dark coppery amber with burnished copper highlights.
• Nose: Pungent molasses, treacle, toffee, honey, and vanilla with oak, cinnamon, nutmeg, and ginger.
• Body: Full-bodied with a more enhanced flavor profile than the lower proof Blue Label. The elevated proof reveals Demerara depth unavailable at standard strength.
• Finish: Long and, despite its strength, smooth and mellow. The Guyanese Demerara base provides a rich, sustained finish that the strength enhances rather than sharpens.

Frequently Asked Questions

• What does Pusser's Gunpowder Proof taste like? Pungent molasses, treacle, toffee, honey, and vanilla on the nose with oak, cinnamon, nutmeg, and ginger. Full-bodied on the palate with the enhanced Demerara depth that overproof strength reveals. Long, smooth, mellow finish despite the elevated ABV.
• What is Gunpowder Proof? The Royal Navy tested rum strength by pouring it onto gunpowder and attempting to ignite it. If the mixture burned, the rum was "at proof" — the Pusser hadn't watered it down. This historical test corresponded to approximately 57% ABV on the modern scale. The Pusser's Gunpowder Proof expression is produced at that original Admiralty strength.
• How does Gunpowder Proof compare to the Pusser's Blue Label? Both use the same Admiralty Demerara-dominant blend. Gunpowder Proof (54.5% ABV) delivers a more enhanced, concentrated flavor profile — the elevated proof reveals Demerara depth, spice, and complexity that the Blue Label (40% ABV) partially suppresses. For those who want the full Pusser's Admiralty experience, Gunpowder Proof is the definitive expression.
