Vacu Vin wine saver, a wine bottle vacuum pump that extracts the air out of the bottle while resealing it with a reusable stopper. This gadget is great! It keeps previously opened wines fresh and tasty for weeks by removing air from the bottle, therefore decreasing the oxidation rate of the wine.
I have been using these stoppers for years to keep my wines fresh. I can keep bottles of red and white wine in my fridge for weeks without having to worry that it will turn into vinegar. Now it's easier to use wine as a cooking staple - always available to give soups, stews, or sauces extra flavor, or just for that one much-needed glass after a long day.
