For the fictional alien species the Grog (or sessile grog), from Larry Niven's Known Space universe, see Thrintun and Tnuctipun.

Grog is also a type of clay, see Grog (clay).

Grog is an alcoholic beverage made with water and rum. The date of its invention varies from 1730 to 1741, but most agree that it was invented by British Admiral Sir Edward Vernon (1684–1757). Modern versions of the drink sometimes include lemon juice, lime juice, cinnamon or sugar to improve the taste. Rum with water, sugar and nutmeg was known as Bumboo and was more popular with pirates and merchantmen.

In the British Navy, up until 1970, every sailor was given a daily ration of rum. Rum was favored by the navy, because it took longer to spoil compared to other liquors. However, this caused additional problems, because some sailors would save up the rum rations for several days, then drink them all at once. Due to the subsequent illness and disciplinary problems, the rum was ordered to be mixed with water. This both diluted its effects, and would make it spoil faster.

When it was determined that daily doses of vitamin C prevented the disease scurvy, citrus juice (usually lime or lemon juice) was added to the recipe.

The sailors named the watered down drink grog, after its inventor — the admiral was nicknamed Old Grog, after the grogram coat he always wore.
