How many carbs are in apple juice?
One cup of apple juice has about 28g of carbohydrate and virtually no fiber, so almost all of it hits the bloodstream quickly. That is more carbs than a medium apple with a fraction of the benefit.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 cup (248g) | 28.0g | 0.5g | 27.5g |
| 1 fl oz (31g) | 3.5g | 0.1g | 3.4g |
| 100 grams | 11.3g | 0.2g | 11.1g |
Net carbs
One cup of apple juice has about 27.5g of net carbs, which is total carbs (28g) minus just 0.5g of fiber. Juicing removes nearly all fiber from the fruit, so the net and total carb counts are almost identical. See the net carbs guide for context on when fiber matters.
Glycemic index of apple juice
The glycemic index of apple juice is about 41. Even though fiber is stripped out during pressing, apple juice still has a moderate glycemic index. The polyphenols and organic acids from the apple slow glucose absorption somewhat, but the rise is faster and sharper than eating a whole apple.
For diabetes
A cup of apple juice is 28g of fast carbs with almost no fiber buffer. It raises blood glucose faster than a whole apple with the same carb count. Many people drink a full 12 to 16 oz glass without thinking of it as a carb load, but that is 42 to 56g of carbs before a meal even starts. Treat it the same way you would treat soda for dosing purposes. See the diabetes carb-counting guide.
Keto and low carb
One cup of apple juice has about 27.5g of net carbs, which exceeds a full day's keto budget of 20 to 30g in a single drink. Apple juice does not fit any version of a keto diet. Even a 4 oz pour is about 14g of net carbs.
Good to know
Unsweetened apple juice and apple cider have nearly identical carb counts per cup. Added-sugar versions stack more on top. Apple juice cocktails and blends often contain corn syrup and can run 35g or more per cup. The USDA data here is for unsweetened juice with added ascorbic acid, the most common store variety. Cloudy apple juice retains a small amount of polyphenols but not meaningful fiber.

How many carbs are in apple juice?
One cup (248g) has about 28g of carbohydrate. An 8 fl oz glass is the same as one cup, so also about 28g. A 12 oz serving has about 42g.
How many net carbs are in apple juice?
About 27.5g per cup. Apple juice has virtually no fiber, so net carbs and total carbs are almost the same number.
Is apple juice bad for diabetics?
It is a fast-acting carb load with almost no fiber. One cup is 28g of carbs that enters the bloodstream quickly. Many diabetes care teams treat juice like soda for dosing. A whole apple is a significantly better option if you want that flavor.
Does apple juice spike blood sugar?
Yes, faster than a whole apple. The glycemic index of apple juice is around 41, which is moderate, but the lack of fiber means the rise starts sooner and the peak is higher compared with eating the whole fruit.
How does apple juice compare to a whole apple for carbs?
A cup of apple juice has about 28g of carbs, similar to a medium apple, but the juice has only 0.5g of fiber versus 3g in the whole fruit. That fiber difference is why the whole apple raises blood sugar more slowly.
