Interesting that the site cannot get the Nelson connection right either....

Lime juice to prevent scurvy was a fairly important ingredient in grog, ... from it we get the words 'groggy' meaning intoxicated, staggery, as you would be drinking half a pint of rum a day, whether with water or not... and limey, a American slang word for a British ship or sailor.

And of course, the recipe for Cuba Libras.....
