After some researching, this is what I got.
Q1: Once I have opened the wine; how long will it last?
A1: Wine is alive, like a flower. When you purchased the flower, it was a bud. A day later, the flower opens. Two days later, the flower is losing its structure and its beauty. The same applies to wine. It is hard to hold a wine together for more than a few days. By the second day after it has been opened, most wines I have tasted have shown evidence of deterioration. Some wines hold together pretty well until day three, but only occasionally.
Q2: Once a bottle is open, is there anything I can do to help my wines age well?
A2: First of all, eliminate the oxygen as much as possible. The best way to do that is to transfer any "leftovers" to a smaller container that doesn’t leave a gap in between the wine and the lid. If this is not possible, there are a few quick things you can do to the bottle you have opened.
- Use a nitrogen gas that is heavier than oxygen to push the air out the top of the bottle.
- Pump the air out of the bottle.
- Fill the bottle with "wine beads" to fill the depleted void remaining after the wine has been drank. "Wine beads" will not rust or mildew or influence the flavor at all.
- Drink the wine quickly.
- Cook with the wine that goes bad. You have many weeks to do this.
