The goal of commercial growers is to produce apples that are 7 to 8.3 cm in diameter, according to market preferences. Some buyers, especially Japanese, prefer large apples, while apples less than 5.7 cm in diameter are of little value in the market and are commonly used for fruit juice.
The apple fruit should have a smooth, light and translucent skin and should be firm and blotchy. Keep in mind that an apple that is heavier than its size will have a higher quality. Apple fragrance is also one of the important parameters in determining the quality of apples that of course requires a variety of varieties.
