Does red wine cause lactic acid?
Fermentation of Sugars
A less serious form of lactic spoilage can occur in dry wines. In these wines the LAB utilizes pentose sugars, trace amounts of glucose and fructose, and produces lactic and acetic acid as a by-product. When sugars are attacked by LAB, lactic and acetic acids are produced.
