The Pinzon Wine Vacuum Pump with Stoppers lets you store wine after opening bottle and keeps it fresh for 2 weeks by ending the oxidation process. Constructed of satin-brushed stainless steel, sturdy plastic, and silicone
If you wonder why your wine taste different after 2 days of being open then you need this vacuum pump. Just replacing a half open bottle with a cork allows oxygen to enter into the wine and eventually will create vinegar. This pump removes the oxygen so that your wine will be preserved in the same fashion as you enjoyed it on the first opening.
