Is it good or bad that grape skins are difficult to peel (what is the reason why grape skins are difficult to peel)

1. In order to make the grapes look good when they are sold, merchants usually pick them in advance. At this time, the grapes are not fully ripe, and the grapes themselves are hard. Although they are easy to store and transport, this is also the reason why they are difficult to peel. Some varieties, such as red grapes, are difficult to peel.

2. The way to solve the difficulty of peeling is to put the bowl with grapes in the freezer of the refrigerator and freeze it for about 3-4 hours. The time should not be too long, otherwise the grapes will freeze. When the freezing time is up, take out the grapes and soak them in salt water for about 1 minute. We just need to squeeze the grapes by hand, which is very convenient.
