Calories in Grape Juice: Full Nutrition Breakdown

100% Concord grape juice is a naturally sweet and flavorful beverage that provides approximately 152 calories per 8 oz glass, with all of its calories coming from natural fruit sugars. It is a notable source of potassium and contains polyphenol antioxidants, particularly resveratrol and flavonoids, which are the same beneficial compounds found in red wine. Grape juice is one of the higher-calorie fruit juices due to the naturally high sugar content of grapes.

Calories by serving size:

Grape juice is calorie-dense for a beverage, with a 12 oz glass containing 228 calories and 54 grams of sugar. Despite being 100% juice with no added sugar, the natural fructose and glucose content is quite high. For those looking to enjoy grape juice while managing calories, a 4 oz serving provides the polyphenol benefits at a more moderate 76 calories, and diluting grape juice with water or sparkling water is another popular strategy.

Frequently Asked Questions (FAQ)

How does grape juice compare to red wine nutritionally?

An 8 oz glass of grape juice has about 152 calories compared to roughly 200 calories in 8 oz of red wine. Both contain resveratrol and polyphenol antioxidants, though grape juice provides these without the alcohol. Research suggests that Concord grape juice offers cardiovascular benefits similar to red wine, making it a suitable alternative for those who do not consume alcohol.

How much sugar is in grape juice?

An 8 oz glass of 100% grape juice contains approximately 36 grams of sugar, all of which is naturally occurring from the fruit. This is comparable to the sugar content of a 12 oz can of cola, though the sugar in grape juice comes with vitamins, minerals, and antioxidants. Because of the high sugar content, most dietary guidelines recommend limiting juice to 4 to 8 oz per day.

Is grape juice healthy?

Grape juice provides meaningful amounts of potassium, vitamin C, and polyphenol antioxidants that have been linked to improved cardiovascular health and reduced inflammation. Studies have shown that Concord grape juice may help support healthy blood pressure and improve blood vessel function. However, its high natural sugar content means it should be consumed in moderation, and eating whole grapes is generally preferable because of the additional fiber.

What is the difference between white and purple grape juice?

Purple (Concord) grape juice has about 152 calories per 8 oz and is significantly richer in polyphenol antioxidants, particularly resveratrol and anthocyanins, which give it the deep purple color. White grape juice has a similar calorie count at about 150 calories per 8 oz but contains far fewer antioxidants. If you are drinking grape juice for its health benefits, Concord grape juice is the better choice due to its substantially higher antioxidant content.

How does grape juice compare to eating whole grapes?

One cup of whole grapes contains about 104 calories and 1.4 grams of fiber, while 8 oz of grape juice has 152 calories and virtually no fiber. Whole grapes are more satiating because the fiber slows digestion and helps regulate blood sugar, whereas juice delivers a more concentrated dose of sugar that is absorbed quickly. Nutritionists generally recommend choosing whole fruit over juice, though grape juice does provide a more concentrated source of certain polyphenol antioxidants.
