I don't always put away a whole bottle of wine, certainly not alone, and also with my wife, we might just settle for a glass each at dinner. I either return the cork, or use a stainless steal and silicone stopper. Should I refrigerate? I don't, but sometimes lose the bottle. Any tricks?
I know they sell vacum seals that can be reused over and over again. They can be found at a wine making store.
I would try to drink the bottle within the week if possible. However, older wines sometimes lose a lot of flavor after only a few hours of oxidation. I use the Vacuvin, which is one of the vacuum seals that bob1 is talking about. I've had pretty good luck with that tool.
I agree the vacuum type sealers work best, still better to drink within a week. Also I do refridgerate, but if I am going to have wine I let it warm up in the glass to a warmer temp. It seems to take much longer to turn if I store an opened bottle in the fridge even if it is blasphemy.
I found a nifty trick for keeping wine fresh while browsing in our local winery and it actually works pretty well. As a general rule you shouldn't try to make an open bottle of wine last for more than three days, but if you aren't able to finish it try freezing it. Obviously you will want to make sure you have drunk a couple inches off it, then tightly recork the bottle and put it in the freezer. When you're ready to use it again just let it thaw in the fridge and you'll be good to go...I haven't had a bad experience doing that yet!
I personally prefer red wines to whites. Since I love alone I often have left over wine after the bottle has been opened. I have found two tricks which do help to preserve the character and flavor of red wines.
1. Store the left over wine in a plastic bottle. Empty, clean and dry water bottles will work very well, they are inexpensive and convenient. Pour the wine into the bottle to the top. This keeps air from contacting the wine. If the wine does not reach the top of the bottle, you can squeeze the sides of the bottle a bit and as the wine rises to the top of the plastic bottle, the air is removed. Then, cap it and store in the refrigerator. It's not very pretty way to store your wine, but it keep it fresh for a longer period of time.
2. Air pumps. I have one and use it but I have found that it is not as foolproof as the method mentioned above.
3. The best method is to have a friend who helps you finish the wine. If, however, you do store wine, I have found it is best to finish it within a couple of days.
Q. How do I keep an open bottle of red wine fresh?
A. Drink it straight away!
The idea of putting it in a water bottle is excellent! Thanks for sharing that one, it seems so obvious now that you've mentioned it. I've just finished half a bottle and done just that, and now that bottle is squeezed and hardly any air left in the bottle and in the fridge. I feel pretty confident about leaving that in there now until I next decide to have some or even sharing it without worrying too much about the taste. I've kept the original bottle, and might transfer it back before serving as that might be easier and more elegant than explaining why the wine is coming out of a small water bottle
The squeezing of the bottle (plastic) is what I saw all over Europe. My husband's nephew told me that a lot of folks go straight to the winery and get their plastic bottles filled there... then they squeeze out the air and re-cap it as they go
