The last pipe of Up Spirits
On the morning of 31 July 1970, the Royal Navy issued rum to its sailors for the last time. At six bells in the forenoon watch, 11am, the pipe of Up Spirits sounded as it had for generations, and ratings queued at the rum tub for a final measure.
The fleet treated the moment as a bereavement. Sailors wore black armbands. Some ships and shore establishments staged mock funerals for the tot; at HMS Collingwood, the navy’s electrical training establishment at Fareham, a procession followed a black coffin with drummers and a piper. Some men drank their final tot in silence. Others poured it over the side, giving the rum back to the sea.
The date passed into naval memory as Black Tot Day. It ended a daily ritual that had structured life afloat for more than three hundred years, and it is still marked by rum drinkers every 31 July.
Three centuries of the tot
The ration that died in 1970 was the survivor of three centuries of change. Rum earned its place in the navy by accident of empire, was watered down by one admiral’s order, and was then cut repeatedly as attitudes to drink at sea hardened.
Rum replaces beer
The sailor’s traditional ration was beer, with wine or brandy substituted on stations where beer would not keep. The capture of Jamaica in 1655 changed the arithmetic. Rum was plentiful and cheap in the Caribbean, it survived long voyages where beer spoiled, and it gradually replaced other spirits in the daily issue. By the eighteenth century rum was the standard ration across much of the fleet, served neat and, for a period, twice a day. Men saved their servings and drank them together, and the drunkenness that followed became a discipline problem the navy could not ignore.
Old Grog waters the rum
In August 1740 Admiral Edward Vernon, commanding in the West Indies, ordered that the daily half pint of rum be mixed with a quart of water and issued in two servings, one in the forenoon and one at the end of the working day. The sailors already called Vernon Old Grog after the grogram cloak he wore on deck, and the name transferred to his watered rum. Grog entered the language. Lime juice and sugar were sometimes added to the mix to soften the taste of stored water.
The shrinking tot
The ration kept shrinking. In 1824 the daily issue was halved to a quarter pint. In 1850 the Admiralty’s Grog Committee recommended abolishing it entirely; the navy compromised, halving the ration again to one eighth of a pint and ending the evening issue. That measure, the tot, held for the next 120 years. It was issued once a day at midday, neat for senior rates, who called it neaters, and diluted with two parts of water into grog for junior ratings. The rum itself was a blend built largely on Demerara and Trinidad stock, issued at 95.5 proof, about 54.6% ABV, stronger than almost anything poured ashore.
Why the ration ended
The tot was retired by the modern warship. In 1969 the Admiralty Board concluded that a daily issue of spirit at that strength no longer belonged aboard ships built around complex and often delicate machinery and weapons systems. A rating might draw his tot and return to a missile console or a flight deck. The board’s case was safety, not temperance.
The decision did not pass quietly. On 28 January 1970 the House of Commons argued it out in what became known as the Great Rum Debate, with the tot’s defenders pressing its value to morale and tradition. The board held its ground, and the final issue was set for 31 July 1970.
There was compensation. The government paid £2.7 million into a new Sailors’ Fund, soon nicknamed the Tot Fund, to provide amenities for ratings, who were given a central role in deciding how the money was spent.
The tot’s legacy
The daily issue ended in 1970, but the tot left durable marks on naval custom and on rum itself.
Splice the mainbrace
The order to splice the mainbrace, originally an extra ration for the men who repaired a ship’s mainbrace, survived Black Tot Day as the one remaining route to an official rum issue. It may be given only by the monarch, certain senior members of the royal family or the Admiralty Board, and it has been used sparingly: for the royal wedding of 1981, for the jubilees of 1977, 2002 and 2012, and for the Trafalgar 200 fleet review in 2005. When the order is given, entitled personnel over 18 receive a single extra measure of spirits.
Navy strength, and the last tot in the world
Navy rum also survives as a strength. Pursers once proved their rum by dousing gunpowder with it; if the powder still lit, the spirit stood at or above proof. The navy’s rum was issued a shade below that mark, at 95.5 proof, and rum sold as navy strength today, typically bottled around 54.5% ABV or higher, keeps the association. Our guide to ABV and proof explains the arithmetic behind the gunpowder test.
The Royal Navy was not the last to pour a daily tot. The Royal New Zealand Navy carried the tradition on for another two decades. Its Chief of Naval Staff took the decision to end the issue in December 1989, and the final ration was poured on 28 February 1990, closing the practice worldwide.
Marking Black Tot Day
Black Tot Day falls on 31 July every year, and rum drinkers have adopted it as the spirit’s quiet memorial. There is no fixed ritual. The observances that have grown up simply borrow the navy’s own habits.
The simplest is a measured tot at midday: one small pour of good rum, taken neat as the senior rates took theirs, or lengthened with two parts of water into grog. A navy-strength rum makes the day literal. The toast comes from the rum tub itself, which carried the words The Queen, God bless her around its side; the loyal toast, now to the King, still fits the occasion.
Bars and rum clubs run tastings on the night, and bottlers time navy-strength releases to the date. None of that is required. The day asks for nothing more than a small glass and a moment’s thought for the sailors who drew their last ration in 1970.
Drinks for the day
The Field Manual covers the serves that suit the date. Navy Grog is the direct descendant of Vernon’s order, rum cut with lime and water. Rum Punch scales the shipboard tradition for company, and the Painkiller shows how far navy-style rum travelled after the tot ended. Our house serve for the day is the Storm & Spice, built on Expedition Spiced Rum.
Born on Black Tot Day
Jerry Can Spirits was founded on 31 July 2025, Black Tot Day, a deliberate nod to the naval rum tradition. The company was started by Dan Freeman and Rhys Williams, both Royal Signals veterans, and remains veteran-owned. Five per cent of profits go to military charities.
The first expression, Expedition Spiced Rum, launched in April 2026: a spiced rum on a Caribbean rum base, macerated in small batches by our British partner distillery. On Black Tot Day 2026 the brand turns one. We will mark the anniversary the way this guide suggests, with a measured tot at midday.

Frequently Asked Questions
What was Black Tot Day?
Black Tot Day was 31 July 1970, the last day the Royal Navy issued its sailors a daily rum ration. Sailors wore black armbands and some ships held mock funerals for the tot. The name now marks the anniversary each year.
What was the daily tot?
The tot was one eighth of an imperial pint of rum, about 71ml, issued at midday at 95.5 proof, around 54.6% ABV. Senior rates drank it neat and called it neaters; junior ratings received it diluted with two parts of water, known as grog.
Why did the Royal Navy stop the rum ration?
The Admiralty Board concluded in 1969 that a daily issue of strong spirit was not compatible with the machinery and weapons systems of a modern navy. Parliament argued the decision in the Great Rum Debate of January 1970, and the final tot was issued on 31 July 1970. The Treasury paid £2.7 million into a Sailors’ Fund in compensation.
What does splice the mainbrace mean?
Splice the mainbrace is the order for an extra issue of rum, originally a reward for the sailors who repaired a ship’s mainbrace. It survived the end of the daily ration and may be given only by the monarch, certain senior royals or the Admiralty Board, usually for royal or national occasions.
When is Black Tot Day 2026?
Black Tot Day falls on 31 July every year. In 2026 that is Friday 31 July, 56 years after the final issue. It is also the first anniversary of Jerry Can Spirits, which was founded on Black Tot Day 2025.
