Blackberry Infused Water Calories

DetoxWater Editorial Team•Published November 5, 2026

Blackberry infused water usually has 0–10 kcal per 250 ml when blackberries are steeped without being squeezed or eaten and no sweetener is added. For a recipe-specific estimate, use the ai nutrition analyzer; it cannot measure exactly how much sugar transfers into the water. The calorie count for blackberry infused water changes if you squeeze or eat the fruit, add sweetener, or serve a different amount.

How many calories are in blackberry infused water?

The usual estimate is under 10 kcal per 250 ml glass, not a laboratory measurement. Plain water contributes no calories, but some natural sugar can move from the blackberries into the water. The amount is not known precisely and can vary with the fruit and preparation.

Steeping is different from blending or eating the whole fruit. If you eat the blackberries, their calories count too; if you squeeze them, more juice and sugar can enter the drink. Sugar, syrup, juice, or other caloric additions also increase the total.

For a consistent, unsweetened batch, use:

  • 1 litre water (about 4¼ cups)
  • 150 g blackberries (about 1 cup)
  1. Wash the blackberries and add them to the water without squeezing them.
  2. Refrigerate for 2–4 hours to infuse.
  3. Serve the water without eating the fruit if you want to use the under-10-kcal estimate.

Keep the batch refrigerated and drink it within 24 hours for best flavour. Discard it after 2–3 days, or sooner if it becomes cloudy, slimy, or sour-smelling; do not leave it at room temperature for more than a few hours.

What are the nutrition facts per 250 ml?

USDA FoodData Central lists nutrients for raw blackberries, not a measured analysis of this particular infused water. The table separates the general calorie estimate from amounts that cannot be calculated reliably from the available data.

For comparison, USDA FoodData Central lists the following for 100 g of raw blackberries. These are fruit values, not values for a glass of infused water.

NutrientPer 100 g raw blackberries
Calories43 kcal
Carbohydrate9.61 g
Total sugars4.88 g
Fibre5.3 g
Protein1.39 g
Fat0.49 g
Vitamin C21 mg
Potassium162 mg

Those fruit values help if you eat the berries. For example, 150 g of raw blackberries contains approximately 64.5 kcal. If all the water and berries in the batch above are divided evenly into four servings and everything is consumed, each serving supplies about 16 kcal from the blackberries. Each serving contains about 250 ml of water plus the fruit.

That calculation already accounts for the whole fruit, including any of its calories that moved into the water. Don’t add the under-10-kcal infused-water estimate again. If the berries are discarded, their whole-fruit calorie value should not be assigned to the water.

How does it compare with juice and soda?

Unsweetened blackberry infused water generally has fewer calories than a comparable serving of juice or regular soda. Juice contains fruit sugars in the liquid, while regular soda typically contains added sugar. The exact difference depends on the product and serving size, so check its label rather than assuming all juices or sodas have the same calories.

DrinkWhat affects its calories?
Blackberry infused waterUsually under 10 kcal per 250 ml when steeped without sweetener and the fruit is not eaten
JuiceThe amount of fruit sugar and any added ingredients; values vary by product
Regular sodaThe type and amount of caloric sweetener; values vary by product
Diet or zero-sugar sodaUsually few or no calories, depending on the product

Eating the blackberries provides the fruit’s fibre and other nutrients, whereas the amounts transferred to infused water are unknown. Choose the comparison that matches what you actually consume: water alone, water plus fruit, or a sweetened drink.

Frequently asked questions

Can I use frozen blackberries?

Yes. Choose unsweetened frozen blackberries and keep the water refrigerated while it infuses.

Does a darker colour mean more calories?

Not necessarily. Colour alone cannot tell you how much sugar or how many calories have transferred into the water.

Does crushing the blackberries change the calorie estimate?

It can release more juice and fruit solids into the water, so the usual estimate for steeped, unsqueezed fruit may not apply.
