I also learned from the Oxford English Dictionary that the 1800s also gave us a drink called Badminton cup, or simply Badminton, which also gets its name from the estate. It was described as one bottle of red Burgundy, one quart of German Selzer-water, and the rind of one orange.
Badminton: Capitalized or Lowercase?
So the next time you watch a badminton game (lowercase when it refers to the game, even though its derived from a place name because it is in such wide use), you can imagine you are on an expansive English estate and enhance your enjoyment by sipping on a cool Badminton cup (in which Badminton was uppercase in all references I found, probably because it’s not widely known and is still strongly associated with the estate).
