The Zos wine saver is an innovative kitchen appliance that gives wine drinkers the ability to store open bottles of wine for extended amounts of time. The simple device promises to remove 100 percent of the oxygen in an opened bottle of wine, and can keep it tasting fresh for weeks or even months after its initial opening. The Zos wine saver is able to remove oxygen thanks to oxygen-absorbing cartridges, which can purportedly work on up to 10 bottles of wine.
While it is possible to remove up to 99 percent of oxygen from wine bottle with a vacuum pump, the team behind Zos wine saver claims that this method is inferior. According to the brand, vacuum pumps lack the ability to accurately remove oxygen and will not preserve wine in an efficient way. The Zos wine saver currently comes in a full kit, complete with an airtight bottle stopper, an oxygen-absorbing cartridge, the counter-top electronic cartridge tester and a sleek storage case; additional cartridges and stoppers can be purchased separately.
