Do I need to add water to squeeze grape juice

Extracting grape juice generally does not require adding water. Fresh grapes themselves contain abundant moisture, and directly extracting juice can preserve their original flavor and nutrition. If the sweetness of grapes is too high or the texture is thick, a small amount of water can be added to adjust the taste. The concentration and flavor of grape juice mainly depend on the grape variety and maturity. Most grape varieties such as Kyoho and Xiahei have sufficient juice, and the flesh and juice naturally separate during juice extraction without the need for additional water. The juice extracted from these grapes has a rich color, balanced sweetness and acidity, and is rich in minerals such as anthocyanins, vitamin C, and potassium. If using varieties with thin skin and thick flesh such as seedless red extract, the texture may become thicker after juicing. At this time, adding no more than one-third of the amount of fruit flesh can improve fluidity, but it will slightly dilute nutrient density. In rare cases, it may be necessary to add water to assist in juicing. For example, when using frozen grapes, if the cell structure is damaged and the juice yield decreases, a small amount of warm water can be added to assist in extraction; When making grape juice for young children to drink, it can also be diluted appropriately to reduce sugar intake. Please note that adding water can accelerate oxidation and discoloration. It is recommended to drink the juice as soon as possible after juicing, or add a small amount of lemon juice to delay browning. When restoring concentrated grape juice produced in industry, water needs to be added in proportion, while homemade grape juice does not require this step.

Before juicing fresh and ripe grapes, they can be soaked in light salt water to remove surface residues and retain grape skins, which can increase the content of antioxidant substances. For those with gastrointestinal sensitivity, it is recommended to filter fruit residue before drinking to avoid excessive intake of dietary fiber that can stimulate the gastrointestinal tract. It is suggested that the daily drinking of grape juice should be controlled within 200 milliliters. Patients with diabetes should consult a nutritionist to adjust their intake to avoid affecting the stability of blood sugar.
