Origin Of The Term Grog
THE British sailors had always been accustomed to drink their allowance
of brandy or rum clear, till Admiral Vernon ordered those under his
command to mix it with water. The innovation gave great offence to the
sailors, and for a time rendered the commander very unpopular among
them. The admiral at that time wore a grogram coat, for which reason
they nicknamed him Old Grog, &c. Hence, by degrees, the mixed liquor
he constrained them to drink universally obtained among them the name of
grog.
