A bergamot-flavoured black tea from Earth and the favourite drink of Jean-Luc Picard, who orders it from the replicator with the same three words throughout his career.
Earl Grey tea is the drink most closely linked with Captain Picard. His order to the replicator, naming the drink, the blend and the temperature, is heard for the first time in the second-season episode Contagion, at a moment when an Iconian computer program has corrupted the ship's systems and the machine produces a potted plant instead.
The order recurs through the rest of The Next Generation, usually in the ready room.
The habit continues into Star Trek: Picard, where the retired admiral, living on his family vineyard, asks for the decaffeinated version.
