Which grape has the highest sweetness

Sunshine rose grapes usually have the highest sweetness, with a sugar content of over 20%. The sweetness of grapes is mainly influenced by factors such as variety, light, temperature difference, maturity, and cultivation method.

1. Sunshine Rose

Sunshine Rose is a popular Japanese hybrid variety in recent years, with dense and seedless flesh and excellent sugar acid ratio. After maturity, it presents a yellow green color with a rose aroma. The soluble solids content generally exceeds 18%, and some high-quality fruit production areas can reach 22%. This variety requires refined management, with high requirements for temperature difference between day and night and light duration.

2. Golden Finger

Golden Finger grapes have a long conical shape and a shiny golden skin, belonging to the high sweetness and low acidity variety. The average sugar content is around 19%, and the sweetness of some single spikes can reach 21%. Its uniqueness lies in the fact that the flesh has a rock sugar flavor, and there is a significant accumulation of sugar in the later stages of maturity. Suitable for planting in dry climate areas, with strong fruit storage and transportation resistance.

3. Red grapes

The sweetness of red grapes remains stable between 17-20%, with large grains and thin skin. After being planted in Xinjiang and other areas, the varieties introduced from the United States accumulate more sugar due to the large temperature difference between day and night. When the fruit is dark red, the sweetness reaches its peak, and the sweetness becomes more pronounced after refrigeration, but the acidity slightly increases.

4. Jufeng

The sweetness of Jufeng grapes is about 16-18%, which is above average. The purple black skin wraps around juicy flesh, and when ripe, it has a strawberry aroma. Although the sugar content is not the highest, the moderate acidity makes its sweetness more refreshing. This variety has a wide adaptability and can maintain stable sweetness in different climatic regions.

5. Xia Hei

Xia Hei usually has a glucose content between 15-17% and belongs to early maturing and high-yielding varieties. When fully ripe, it appears purple black in color, with thick fruit powder and a pure and pure sweet taste. Although not as sweet as the previous varieties, it has become a common sweet grape choice in the mass market due to its high yield and strong disease resistance. When choosing high sweetness grapes, it is recommended to observe whether the stem is fresh green, whether the powder is evenly distributed, and whether the fruit should have elasticity when lightly pinched. The sweetness performance of different varieties is closely related to the planting environment, and grapes in production areas with large temperature differences between day and night, such as Xinjiang and Gansu, are generally sweeter. Pay attention to control the amount when eating, and patients with diabetes should consult a nutritionist. Eating with a small amount of yogurt or nuts can slow down the rate of blood sugar rise. Do not wash with water when storing, store in the refrigerator compartment for 3-5 days.
