Tea

Tea was a drink made from the dried leaves of the tea plant, created by brewing the leaves in hot water. The Fifth Doctor once described it to Will Chandler as "a noxious infusion of oriental leaves containing a high percentage of toxic acid". Will thought it sounded vile, to which the Doctor replied, "Personally, I rather like it". (DW: The Awakening)
