The sweetest apple variety is the Aksu rock sugar heart apple from Xinjiang
. This kind of apple is famous for its delicate appearance, golden color, crisp and sweet meat, and rich aroma, and is called “the treasure of Tianshan Mountains”. The sugar content of Aksu Rock candy heart apple is as high as 18%, and the sweetness can reach 17-21 degrees, which is about 20% higher than ordinary apples, so it has the reputation of “the sweetest apple”
. Its unique sweet taste is mainly due to the unique climatic conditions of Aksu region, including less cloud cover in summer, long and abundant sunshine, and large temperature differences between day and night, which are conducive to the accumulation of more sugar in the apple during growth
