Tartaric acid is found in many plants, e.g., grapes; this natural acid is chiefly the dextrorotatory d -tartaric acid, called also d -2,3-dihydroxysuccinic acid or l -2,3-dihydroxybutanedioic acid. This form can be partially converted to the others by heating it with an aqueous alkali, e.g., potassium hydroxide.

Tartaric acid is often used as an acidulant in grape- and lime-flavored beverages, gelatin desserts, jams, jellies, and hard sour confectionery. The acidic monopotassium salt, more commonly known as 'cream of tartar,' is used in baking powders and leavening systems.
