How to preserve grapes?
1, sealed with plastic wrap.
Grapes don't need to be washed, put them directly on the plate and seal them with plastic wrap to prevent a lot of air from slowing down oxidation.

If the grapes are washed clean, they must be refrigerated to slow down the deterioration as much as possible. The temperature should not be too low or too high, just around zero.
How to choose grapes
1, see frost
The skin of fresh grapes has a layer of naturally formed hoarfrost, which is harmless to human body. The whiter and thicker the grapes, the riper the grapes in bags, and the grapes are safer without contact with pesticides.
Step 2 look at the appearance
Grapes are even in size, full of fruit, and there are no shriveled and cyan fruit. If the stem is moldy, the fruit surface is sticky and wet, the peel is blue-brown or dark-brown, and there are wrinkles on the surface of the epidermis, which indicates that the quality of this bunch of grapes is not good.
3. Look at this color
Generally speaking, ripe grapes are dark and bright in color and smell fruity. For example, seedless white is cyan, rose fragrance and black heart are dark purple, longan is amber, and mare's milk is yellow and white. The closer the colors are to these colors, the better the maturity of this bunch of grapes.
Step 4 touch the fruit stalk
The stems of fresh grapes are hard, and the fruit stalks are loosely connected with the fruit grains, indicating that the received light is sufficient and the sweetness is high. Grapes that have been stored for a long time will fall off with your hands and will not bear fruit.
Step 5 taste it
When trying to eat, choose the bottom one in a bunch of grapes. Because the light is not good and the maturity is not good, the taste at the bottom is weak. If it tastes sweet, it means that the whole bunch of grapes are sweet.
