With the Peugeot Epivac vacuum pump set, you can continue to enjoy a good bottle of wine or champagne even after opening it. This brilliant little vacuum pump fulfils two functions: For wine bottles, it pumps out all air to avoid oxidation for optimal storage. For champagne, it returns air into the bottle to maintain its freshness. This vacuum pump can extend the contents of a bottle for 2–8 days. The Epivac vacuum pump comes with two wine corks and one champagne cork.
