Do wine bottle stoppers work?
Wine stoppers offer practical benefits, extending the life of your favourite bottle of wine. There are several different types of stoppers or pourers on the market, with some more effective than others. They work by sealing the bottle, preventing air from reaching the wine and causing taste-spoiling oxidation. Your most basic stoppers offer a rubberized seal, extending the bottle’s lifespan for a day or two. For a more efficient seal, look for vacuum preservation bottle stoppers. These allow you to pump oxygen out of the open bottle, creating an airtight vacuum seal.
