A tea blend named for an Old Earth British nobleman was Jean-Luc Picard's favorite hot beverage. The tea is infused with bergamot and normally not taken with milk.
In 2365 he ordered a cup from his Ready Room replicator and got a potted plant instead ... an early sign of the Iconian's shipboard computer virus.
Picard's favorite was even known to Duras' scheming sisters during the Klingon civil war, probably thanks to Romulan intelligence, and was another personal secret Data told Kamala, the metamorph. Picard also offered some to Adm. Hanson upon his first visit aboard, on the eve of the Battle of Wolf 359.
