Grape selection
1. Look at the appearance and shape. The appearance is fresh, the size is uniform and neat, the branches and stems are fresh and firm, the particles are full, there are few green and shrunk seeds, and the quality is the best if there is white frost on the outside. When fresh grapes are gently lifted by hand, the particles are firm and there are few seeds. If the grapes fall off one after another, it means that they are not fresh enough. The branches and stems are dry and rusty, the fruit surface is moist, the peel is blue-brown or gray-black, and the skin is wrinkled and threshed.
2. Look at the color. Generally, grapes with moderate maturity are darker and brighter in color. For example, rose fragrance is black and purple, longan is amber and purple-red, giant peaks are black and purple, and milk is yellow and white. Again, taste the smell and taste. The grapes with good quality have a lot of juice and are rich and rich, sweet and fragrant; the grapes with poor quality have little juice or are full of juice and light and have no aroma, and have a distinct sour taste. Finally, taste the grapes. When purchasing, you can try the bottom of a bunch of grapes to determine the quality of the taste.
3. The quality of grapes is related to maturity, and the bottom one in a bunch of grapes is often the least ripe because of the worst degree of light and poor maturity. Therefore, in general, the bottom one is the least sweeter. If the grape is sweet, it means that the whole bunch of grapes is sweet.
Method:
1. Wash the whole bunch of grapes, and remove the broken fruits if there are cracks and broken fruits.
2. Use a towel or paper towel to wipe the moisture on the surface of the grapes.
3. Use scissors to cut the junction of the grape stems and the fruits carefully. If there is residual moisture on the grapes on the inside, you should be wiped dry.
4. Put the cut grapes in the amount you want to eat at a time and ice them in the freezer. This way, the grapes can be stored for more than three months and can be thawed naturally when they are to be eaten, and the flavor will not decrease. You can eat this natural ice hockey directly without thawing. The grapes have a stronger aroma and the astringent taste of the skin is reduced and easier to enter!
