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.

I use the vacuum sealer. I can't down a whole bottle of wine myself in a day or two and the vacuum pump (that comes with special corks) works best for me.
Leftover wine????? :)
I think of moonshine when I think of Mason jars! But I agree with 6ingredientsorless - we use a vacuum sealer for wine.
The owner of my local wine shop agrees: he convinced me to switch to jars in the fridge over vacuum corks. I can definitely taste the improvement. Another nice trick is buying a half-bottle of wine with a screw-top for storage. Less moonshine-y, perhaps?
I do this, but not to preserve half a bottle of great wine. Rather, I keep a jar in the fridge for small amounts of unfinished table wine and add to it whenever my husband or I decides not to finish a glass (we're not talking about really great wine here). I probably wouldn't drink the jar's contents - I keep it in the fridge for much longer than a week - but I use it for cooking because it's usually the wine's acidity and not overall quality that I want in the dish. That way, I don't have to open a new bottle just for cooking.
Ah but opening a bottle "just for cooking" is a great excuse! Then you sip as you cook, and have a glass with dinner... mmm, wine.

What's leftover wine? I've never come across this phenomenon though I hear it mentioned from time to time.
Leftover wine? Does that really happen with people? Never happens in my house!
Really?
I also store up extra wine (or just wine I didn't like much) and save it for cooking. Only I put it into a plastic bag and freeze it.
I agree with hotspicyandskinny. i use wine often to cook and dont always want to open a bottle so i buy a bottle and pour half a cup into ziploc snack size bags. place them on a sheet pan and freeze. once frozen you can put them into a larger ziploc or just leave as is. works great.
