A porrón (Catalan: porró) is a traditional glass wine pitcher, which holds 0.75 litres (25 US fl oz) typical of Spain,[1] originating in Catalonia,[2] in northeastern Spain, and eventually spreading to other parts of Spain.[3] This invention allows everyone to drink from the same utensil without touching it with their lips. It fosters communal drinking accompanying food, though it does require some skill to ensure the wine enters one's mouth and to keep it from spilling onto clothing. The porron resembles a cross between a wine bottle and a watering can. The top of the bottle is narrow and can be sealed off with a cork. Stemming upwards from the bottom of the pitcher is a spout that gradually tapers off to a small opening. It is shaped such that the wine stored inside it will have minimal contact with the air, while being ready to be used at all times. Until the mid-twentieth century it was very common in homes, but the tradition is now slowly being lost. The idea originated as a replacement to bota bags.[citation needed] Porrons are most commonly filled with regular wines, either white or red, but are also used to drink cava, and a smaller version filled with a sweet, dessert wine (typically Grenache) is also common in Catalan restaurants. The lack of contact with the lips allows a group of people to share the same vessel without offending their sense of hygiene.
