A Beginner's Guide to Navy-Strength Rum

By Adam Clark Estes on at

The Royal Navy's successful invasion of Jamaica in 1655 had a lot of terribly negative outcomes. The commanders ended up in the Tower of London. Many of the English sailors fell sick or starved. A lot of Spanish settlers died. But there was one undeniably positive outcome: rum.

After that fated invasion, the Royal Navy started giving its sailors daily rations of domestically produced rum instead of the French brandy they'd been receiving. ("Domestically produced" meaning produced on the captured island of Jamaica, of course.) Referred to as a "tot," this ration of rum measured about half a pint and was given to sailors around midday. The order used to distribute rum rations—"splice the mainbrace"—got its name from one of the most difficult repair jobs aboard it the ship. It remains a euphemism for having a drink today.

In order to insure that the rum hadn't been watered down, the sailors would "prove" the spirit's strength by pouring it on gunpowder and then trying to ignite it. If it lit up, they knew that the alcohol content was greater than 57 per cent. If it did not, the rum was considered "under proof." This is where the term alcohol proof comes from, though it means something slightly different today.

The Royal Navy later tweaked the formula of the rations after the rum had been proved by adding some water and a bit of lime juice to combat scurvy. This healthy cocktail became known as grog after the 18th century British admiral Edward Vernon, better known as
"Old Grog" for the waterproof grogram cloak he wore at sea.

Over the course of the past three centuries, Navy strength rum became the stuff of legend. The deep brown spirit made its way around the world, often in oak grog barrels with brass letters that read "The Queen God Bless Her" or "The King God Bless Him" depending on the reign. Sailors used copper cups of various "measures" to portion out the grog. Since it took little more than molasses to make rum, the Royal Navy had no trouble keeping the kegs full.

Over the centuries, rum rations were reduced again and again until July 31st, 1970, when the Royal Navy put an end to daily rum rations for sailors. Quite obviously, operating heavy machinery and drinking large amounts of alcohol do not mix, even thought each sailor's tot was only an eighth of a pint at that point. The day of the final ration became known as Black Tot Day.

The end of the Royal Navy ration tradition did not spell the end of Navy strength rum, however. In 1979, distiller Charles Tobias obtained the official rum recipe from the Admirality and began selling the same blend of five West Indian rums that used to fill the grog tubs on British warships. Tobias named his new company Pusser's after the slang term for a ship's purser, who originally distributed the rations. Others followed, and now there's a small family of Navy strength rums that smell like alcohol and taste like empire. You're going to love them.

Oh, and if you want to get really authentic and make some grog, try this recipe.

Pusser's Rum Black Label: Gunpowder Proof

A Beginner's Guide to Navy-Strength Rum

Pusser's Black Label rum is arguably as close as you can get to drinking what the Royal Navy once drank. This "Gunpowder Proof" rum clocks in at 109 proof (a little over 54-per cent alcohol by volume) which is just shy of the 57-per cent figure usually used to describe Navy strength. We'll let you conduct your own gunpowder test, though.

Lost Spirits Navy Style Cask Strength Rum

A Beginner's Guide to Navy-Strength Rum

Produced with the highest grade molasses, Lost Spirits Navy Style rum is wonderfully complex, perhaps thanks to being stored in charred American oak casks seasoned with Oloroso Sherry. The first sip almost tastes like a fine single malt whiskey but the sweet finish is nothing but delicious refined rum. Made in northern California, so you know it's fancy.

Smith & Cross Traditional Jamaica Rum

A Beginner's Guide to Navy-Strength Rum

This is the whole package—and also one of the most popular Navy strength rums. Made on the same island where the Royal Navy first made rum a part of their everyday life, Smith & Cross is unfiltered and full of flavour. The brand itself even dates back to a sugar refinery near the river Thames that opened in 1788, when rum first started filling cellars in London.

Rumbullion! Navy Strength

A Beginner's Guide to Navy-Strength Rum

The origins of the word "rum" are debatable, but it's largely believe that it comes from "rumbullion", an archaic English word for a rowdy good time. With a hand-drawn grog tub on the label, this spirit is clearly channelling its Royal Navy roots. Rumbullion promises hints of cardamom, clove and vanilla. It's also extra spicy for extra fun.

Black Tot 'Last Consignment' British Royal Naval Rum

A Beginner's Guide to Navy-Strength Rum

This elegant, extremely hard to find rum comes from the last remaining kegs of Royal Navy rum. That's right: the same stuff the sailors drank. It's chocolately, oaky, anisey—just incredible. A bottle costs as much as a car, but it comes with a free ration cup!
