Once a bottle of wine is open, how long does it stay fresh?!
Answers: just finnish it !!!you need help with that!!!
2 or 3 days. If you put it in the fridge, it's good for up to a week
A week at the most. Make sure you re cork it with a wine stopper to seal in the freshness and refridgerate.
Depends on the type of wine. If you cap it or better yet vacume cap it, expect about 1 week for the average red or white.
2-7 days. Please do not store your reds in the refrigerator. It is too cold. It will mess up their delicate structure and the taste will be altered.
2-3 days if you just re-cork it or use one of those fancy stopper deals. 5-7 if you use a vacuum system (they're pretty cheap). There is no problem putting a red in the fridge. Wine is not that delicate. You would probably want to pull it out for 20-30 minutes before drinking it, but it won't hurt the wine to be in the fridge. Also, there are many sommeliers out there that will put a red in the microwave for 3-5 seconds to bring it to drinking temp.
Red wine a couple of days tops. White about the same but if it is sweet, it will taste ok a little longer.
Mine wine never lasts long enough to lose it's flavor.
Not long. Recapping is essential. Refrigeration helps. The best "preservative" is a shot of nitrogen. You can get canisters at your liquor store. Once the wine has passed its peak, it is still drinkable. After it passes the point where you want to drink it, you can still use it for cooking.
