Plymouth Gin..."Over the centuries, the amount of rum changed from time to time. Prior to 1740, Pusser's Rum was issued to the men neat, that is without water. They received 1/2-pint twice daily!"
"In 1970, the Admiralty Board decreed that there was no place for the daily issue of rum in a modern navy, and so ended the daily issue of Pusser's Rum in the Royal Navy on July31st,1970. This date since then, is referred to "Black Tot Day".
Plymouth Gin...The finest rum ever.
