C)acetic acid bacteria.
D)ethanol.

Accepted Answer

Acetic acid bacteria are the main cause of wine spoilage, as they produce acetic acid (vinegar) from the ethanol in the wine. Sulfur dioxide is commonly added to wine as a preservative to prevent spoilage from bacteria and other microorganisms, carbon dioxide is a natural byproduct of fermentation, and ethanol is the primary alcohol found in wine.
