How long can I keep a bottle of wine that has been opened?

Open wine will not last very long. If you are planning on keeping it at room temperature then you are going to have a few days before your bottle of wine goes south. If you keep it refrigerated, then you might have a week before it goes bad.

This is because wine is like fresh fruit. It can get easily contaminated by airborne bacteria and what ever nasties that may be floating around.

The best way to keep your open bottle of wine is to transfer it into a clean, small container that has less air in it and then seal it tightly. You then need to put it in the fridge right away. You might even want to put it in the freezer so the temperature drops quicker. Just make sure that you don't forget your wine in the freezer because a wine Popsicle is probably terrible. Maybe, I think that I am going to try that tomorrow.

What Temperature Should I Ferment My Wine At?

Room temperature should be ideal for your wine. It is best to make sure that the temperature of whatever room you put it in does not fluxuate and remains constant. 


21-26°C (69-79°F) is the best temperature for fermenting your home made wine.


Just remember that if your wine is cool while you are fermenting it, the process is going to take a lot longer.
