Kegs

kegs, increasingly popular form of wine packaging. The combination of recyclable stainless-steel kegs with plastic tubing and inert gas keeps large volumes of wine fresh. Kegs have been adopted with enthusiasm in many American bars and restaurants as a much more effective deliverer of fresh wine by the glass than bottles. Large bag-in-box packages fitted with pumps are sometimes called kegs. Some retailers particularly concerned with sustainability encourage their customers to fill their own containers from kegs.
