Sailors could lay in their own stores of alcohol. John Fray, a sailor on the Maryland merchantman Rumney & Long in 1747/8 bought twelve gallons of wine, two gallons of brandy, fifteen gallons of cider, and twelve and a half gallons of rum. All told, alcohol cost him four pounds and seventeen shillings, nearly a quarter of all his expenses for the voyage.

On long passages and on foreign stations men drank watered wine (in the proportion of 8 to 1) or watered spirits (in the proportion of 16 to 1), but in home water they drank beer alone, and the length of time a ship could stay at sea was effectively measured by how long her beer would last.Beer was so important, the the ability to brew it made sailors valuable. The cooper John Nicol spent much of his time at sea as a brewer of spruce beer. At least once he was recruited into a profitable voyage for that very skill:
At once I made myself clean and waited upon Captain Portlock. He was happy to see me, as I was an excellent brewer of spruce-beer, and the very man he wished, but knew not where to have sent for me. I was at once engaged on the most liberal terms as cooper, and went away rejoicing in my good fortune.Samuel Kelly related the drinks of choice for the upper and lower decks of an American vessel:
The American officers appeared sober men, as they generally drank water mixed with the bottled porter, though some of the crew had broached a pipe of Madeira wine in the between decks, and cut up the cheese which they fried in the pan to eat.Mixing drinks, as we have seen, was common. Generally this was watering down, which includes the famous sailors' rum drink grog. Grog was a very simple drink, as Francis Grose defines it in the 1785 edition of his A Classical Dictionary of the Vulgar Tongue:
William Spavens, Jacob Nagle, and Samuel Kelly all write of receiving an allowance of grog. Notably, many sailors don't mention grog at all.
Eighteenth century sailors were figuratively awash in liquor. Alcohol formed an important part of maritime culture. That drinking culture was host to a diverse range of drinks, and not defined solely by rum.
