Port

Port was a beverage. The Brigadier's Christmas tradition involved a bottle of port and a good book. (PROSE: Faithful Friends: Part 1)

In March 2006, the Ninth Doctor found a bottle of port from a table in the Cabinet Room of 10 Downing Street, threatening to the Slitheen that he would use his sonic screwdriver will triplicate the flammability of this alcohol. However, a Slitheen realised that he was bluffing. Conceding, the Doctor offered the bottle to Harriet Jones on his right. However, Harriet, holding the Emergency Protocols informed the Doctor that it was to be passed to the left first, and so he handed it to Rose Tyler. Later, after determining the Slitheen's weakness in time to save Jackie Tyler and Mickey Smith from one in the latter's flat, the three celebrated the moment with a glass of port from the bottle. Harriet suggested that acetic acid could be derived by fermenting the port, however, the Slitheen in Downing Street were ultimately dealt with via a different method. (TV: World War Three)
