If you want to keep an open bottle of wine for more than a couple days, there are a lot of fancy gadgets out there to help you. But our friends at Food52 have a great video tip for keeping leftover wine in the refrigerator for up to a week — using just a canning jar and a kitchen towel.
Wine-saving gadgets work because they limit the wine's contact with air, which contains the oxygen that causes wine to oxidize. Food52's trick accomplishes the same goal using a jar that is slightly smaller than the amount of wine to be stored. The jar is placed on kitchen towel and filled to the very top. When the lid is screwed on, the jar should overflow a little, which lets you know there is no air between the lid and the wine. According to the wine experts who gave Food52 this tip, wine stored this way will last up to a week.
