Q: I have a few bottles of homemade red wine that have turned to vinegar. It had a screw cap with a plastic seal around it. The liquid has some sediment, has a strong vinegar odor, and otherwise clear red wine color. 2. Join the discussion today. Instead of the bacteria fermenting sugars, as happens when the wine is made, bacteria from the acetobacter family use the alcohol (ethanol) in the fermentation process. When I took the seal off, but the screw cap was still sealed, I could really smell it. Furthermore, the line of thinking here is that after being opened, this transformation will occur faster. For example, if you open the bottle of brown wine and smell fresh fruit, you may still be in luck; however, spoiled wine smells like vinegar. I am more than sure there are measurable quantities of ethanol present, but they are way too low to matter. This erroneously assumes that vinegar is the natural next step in the evolution of wine and all that is needed it fresh air. Sent by Bill Editor: The wine’s alcohol content and acidity will protect it (and you!) and was told by a Food Scientist to avoid ALL foods that are fermented as well as vinegars, pickled anything, I would say better safe than sorry - especially if on Anabuse medication. That being said, most vinegar has residual alcohol of 0.2%-0.3% by volume because the vinegar fermentation process cannot be taken too far--if all the alcohol is consumed the vinegar-making bacteria begin to metabolize the vinegar into water. The word vinegar arrived in Middle English from Old French (vyn egre; 'sour wine'), which in turn derives from Latin: vinum (wine) + acer (sour).. Chemistry. The first wine myth states that wine, ultimately, will turn to vinegar. When you ask about alcohol, you really mean ethanol. Why? Wine vinegars, such as red or white wine and balsamic vinegar, do start with a dilute wine which is then fermented. As someone who has reacted to .056% alcohol (threw up!) How can I tell if it’s safe to consume? No doubt there are alcohols in the apple vinegar 1. Read the When Wine actually does turn to vinegar... discussion from the Chowhound Wine, Vinegar food community. White wine that turns brown isn't necessarily bad. It’s over 60 years old! However, when the brown color is accompanied by other indicators of deterioration, it is best not to drink the wine. It seems good, but I’m afraid to try it. I got a bottle of pomegranate wine a few days ago. Did it turn to vinegar and lose its alcohol content? The conversion of ethanol (CH 3 CH 2 OH) and oxygen (O 2) to acetic acid (CH 3 COOH) takes place by the following reaction:. I guess air got in the wine since it wasn't sealed good. CH 3 CH 2 OH + O 2 → CH 3 COOH + H 2 O Polyphenols. It tasted really acidic and I felt stone cold sober after drinking 600ml of the wine.
