Grape juice is a sweet beverage made from pressed and filtered grapes, available in purple (Concord) and white varieties. One cup (253g) delivers about 152 calories, 37.4g of carbs, and 35.9g of sugar. Per 100g it provides 60 calories with 14.8g of carbs, placing it among the higher-calorie juice options. Potassium at 104mg per 100g contributes to electrolyte balance. Purple grape juice retains some polyphenol antioxidants from grape skins, including resveratrol and quercetin, though the amounts are substantially lower than in whole grapes or red wine. Grape juice has essentially no protein or fat. The high sugar content (35.9g per cup) is nearly the entire recommended daily limit for added sugars for adults, making it a drink to be used sparingly on a calorie-controlled diet.

Health Benefits of Grape Juice
Purple grape juice contains polyphenol antioxidants from grape skins, including resveratrol, quercetin, and anthocyanins. These compounds have been studied for cardiovascular benefits, and research from Tufts University found that Concord grape juice consumption improved endothelial function and reduced LDL oxidation in healthy adults.
Potassium at 104mg per 100g supports blood pressure regulation by counteracting sodium's effect on fluid retention. A cup of grape juice contributes 263mg of potassium, roughly 6% of the 4,700mg daily recommendation for adults.
The antioxidants in purple grape juice may support exercise recovery by reducing oxidative stress from intense training. However, the polyphenol content in juice is significantly lower than in whole grapes because fiber and many skin compounds are filtered out during pressing.
For athletes, the high natural sugar (mostly glucose and fructose) in grape juice makes it a rapid energy source before or during prolonged endurance exercise. Mixed with water, it can serve as a natural sports drink alternative. However, the calorie density per cup means it is less practical than sports drinks for pure hydration during exercise.
Dietary Considerations
Grape juice is not suitable for keto or low-carb diets due to its 14.8g of carbs per 100g and high sugar content. It is vegan, gluten-free, and dairy-free. For weight loss, grape juice is a poor choice because it delivers 152 calories per cup with negligible protein or fiber to promote satiety. Eating whole grapes is far superior for weight management because the fiber slows digestion and the volume is lower per calorie. For individuals with diabetes or insulin resistance, the rapid blood sugar spike from 35.9g of sugar per cup makes this a drink to avoid or limit strictly.

Frequently Asked Questions
How many calories in grape juice?
One cup of grape juice (253g) has about 152 calories. Per 100g, grape juice contains 60 calories. This makes it one of the higher-calorie fruit juices, comparable to orange juice but higher in sugar.
Is grape juice good for weight loss?
Grape juice is a poor choice for weight loss. A single cup delivers 152 calories and 35.9g of sugar with no protein or fiber to slow digestion or promote fullness. Eating whole grapes is a far better option for the same sweetness with fewer calories.
How much protein in grape juice?
Grape juice contains essentially no protein at 0.4g per 100g and 1g per cup. It is purely a carbohydrate beverage with no meaningful contribution to daily protein needs.
Is grape juice high in sugar?
Yes, grape juice is very high in sugar at 14.2g per 100g and 35.9g per cup. This is nearly the entire 36g recommended daily limit of added sugar for adults in a single glass. Whole grapes or diluting with water are better options.
Does grape juice have antioxidants?
Purple or Concord grape juice contains polyphenol antioxidants including resveratrol, quercetin, and anthocyanins from the grape skins. These have cardiovascular benefits in research, though the amounts are lower than in whole grapes due to the filtration process.
Is grape juice better than soda?
Grape juice is higher in calories (60 vs. 51 per 100g) than most colas, but it does contain potassium and antioxidants that soda lacks entirely. Neither is a good choice for daily hydration. Water, unsweetened tea, or sparkling water with fruit are better options.
