Nah, I invented it a long time ago; well, to be fair: it was me and some nice young waitress at the Las Vegas McCarran Airport. I had a hot black tea and she was young, and the tea was black, and she was refilling complimentary coffee, and she did it. Black is black. My friend from India who saw this almost pissed herself ; ) Mainly because she knew how long it took me to order that tea 10 minutes before ---- let's say it's not too easy to order a tea that is not ice cold and full of ice in US.
Few years later I invented blackwine drink the same way. Red dry wine in a black glass was very dark, and pepsi was black, and it happened. But it tastes pretty cool.
