Save time by reducing your bottling, corking and uncorking. Siphon finished wine into the plastic oxygen-barrier bag, attach the spout, and place the bag in the dispensing container. Each bag holds 1.8 gallons (about 9 bottles' worth) of wine and will keep it fresh for up to 6 months, and the plastic dispensing container is compact enough to fit on a fridge shelf. Bags are intended for a single use. The Wine on Tap dispenser includes one pre-sanitized oxygen-barrier bag with dispensing spout, dispensing container, and spout retainer.
