Apple tree varieties with sour apples

Most apples with a sour taste have a green tint to their skin, with little or no blush. Many people mistakenly believe they contain more ascorbic acid (vitamin C), but this isn't necessarily the case. A sour taste may be due to a lower amount of fruit sugar. Sour apples are not commonly eaten fresh; they are more often used to make preserves, jellies, and compotes. However, it's important to note that the refined sugar content in such dishes will be very high. Below you'll find the best varieties of sour apples.
