tot

"Many tots of Jamaica grog" refers to the traditional rum ration (a "tot") that British sailors received, diluted with water and sometimes with lime juice and sugar. This mixture, known as grog, was a staple in the Royal Navy for centuries and was particularly associated with Jamaica due to its rum production.
‘I devoured Patrick O’Brian’s twenty-volume masterpiece as if it had been so many tots of Jamaica grog.’
