How do you keep wine from turning into vinegar?
Use sulfur dioxide as an antimicrobial agent, keeping free SO2s between 20 to 35 ppm (mg/L). Store your wines in a cool, dry area. The lower temperatures and dry air will discourage not only acetic acid bacteria but molds and fungi as well.
Why does wine turn to vinegar?
Wine turns into vinegar if air has free entrance into the container. With enough oxygen and a temperature of 42-115°F (6-45°C) millions of acetic bacteria living in fermented wine material get active and start to process wine spirit into water and acetic acid.

Is 50 year old wine still good?
