Bottle stoppers can generally be purchased at a range of stores. These include supermarkets, corner shops, and the slightly higher-end of wine stores and off licenses.
A corked bottle of white wine typically lasts about 3 to 5 days once opened if stored in the refrigerator. If the bottle remains unopened, it can last for several years, depending on the type and quality of the wine. However, once exposed to air, the wine begins to oxidize, which affects its flavor and quality over time. To maximize freshness, reseal the bottle with its cork or a wine stopper.
The purpose of a wine stopper is to cork the remaining wine in a bottle before putting it on a rake or into the refrigerator since using the original cork is sometimes difficult to put back into the bottle.
