Acetic acid is made by a bacteria known as acetobacter. This bacteria is everywhere: in the air, on fruit, on grape presses, etc. When acetobacter gets into your wine it can slowly turn the alcohol into acetic acid, if left unhindered.
How do you keep wine from turning into vinegar?
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. Watch wines that have low alcohol levels (below 10 percent).
Why does homemade wine taste like vinegar?
The smell and/or taste of vinegar indicates that a wine has either been badly made or the bottle has been open for too long and has been attacked by a bacteria, called “Acetobacter”. Acetobacter reacts with oxygen and this reaction changes the taste of a wine to a vinegary flavour. In fact, this is how vinegar is made.
Is wine still alcoholic when vinegar turns?
Vinegar is created when bacteria turn ethanol (alcohol) into acetic acid (vinegar). So turning wine into wine vinegar gets rid of the alcohol, and wine vinegar is not intoxicating.

How do you raise the pH of wine?
To increase pH, use a deacidifying agent, such as carbonate salts (e.g., potassium carbonate, potassium bicarbonate), to decrease tartaric acid, or, perform a double-salt precipitation to decrease both tartaric and malic acids in high-TA, high-malic acid wines.

Why does wine suddenly taste bad?
A cooler wine is less expressive; the flavors (as well as the perception of alcohol) can be muted, and tannins will feel tighter and more astringent on your tongue. This is why the taste of your wine can even change as you drink it: it’s getting warmer the longer it sits in your glass.
