2. Look at the shape of the grapes. If the grapes are full, uniform in size and slightly green and shriveled, the quality of the grapes is better. When purchasing, you may wish to consider this type of grapes first, which tastes good.
3. See if the grapes are strong. This means that when you pick up grapes, you should identify whether the fruit stalks and grains are firm. If seeds fall off when picking, it means that some fruit stalks have rotted, so consider changing to a fresher grape.
4. Look at the compactness of these grapes. In the same variety, if the grapes are rich in nutrients, they will grow more closely; If it is malnourished, it will grow loosely. You might as well buy grapes in this way.
5. Try the sweetness of the grapes directly. As we all know, if the quality of grapes is not good, they usually have obvious sour taste, and the lowest grape in a whole bunch of grapes is often the least sweet. So if you taste the grapes and find that the grapes at the bottom are very sweet, it means that the whole bunch of grapes is really sweet.
6. Smell the grapes. If the grapes are fresh and not rotten, there is generally no strong unknown taste, except the fragrance of the grapes themselves. If you can smell alcohol, it means that the grapes have begun to rot.
7. Measure the weight of grapes. This weighing method needs to be carried out in the same variety of grapes. If the weight of two bunches of grapes with similar size is obviously different, it is suggested to choose the one with heavier hand feeling, because this bunch is more delicious.
