Generally speaking, cherries are divided according to their diameters. Common specifications are J, JJ \ \ XJ \ \ SJ, JJJ \ \ P..j, also known as single hook, which is the most basic symbol to describe the diameter of cherry fruit.
JD stands for black and D stands for darkness. JR stands for red, r stands for red; JL stands for red and l stands for light. These three sizes of cherries have relatively small fruit diameters, poor taste, insufficient moisture and easy drying. D stands for black, and no D stands for red. Of course, the logos of each company are different, but they are all the same.
Extended data:
When choosing cherries, you should look at the color of the stems. Bright green fruit stalks are the freshest, and the picking time is very short. If the stem turns yellow, the cherry will not be fresh.
Fruit hardness is also an important criterion for selecting cherries. When pressing fruit, the higher the hardness, the higher the freshness. If it feels soft, the cherry will not be very fresh, and the taste will be slightly worse.
