Frozen Blackberries is 11g of sugar, wrapped in 5g of fiber per 100g. That's what makes it not soda.

The fiber slows absorption; the sugar is not "free sugar" the way added sugar is. Whole fruit and juice are different foods nutritionally, even at the same sugar number.

The chef's caveat

Ripeness matters

A greener frozen blackberries has more starch and less sugar; a spotty one is the reverse. Total calories barely move, but if you are tracking blood sugar or fiber-vs-sugar ratio, ripeness is a real variable — not a rounding error.

How many calories in package (18 oz) of frozen blackberries?

About 326 calories, with roughly 6g of protein. package (18 oz) weighs about 510g. Use the slider above for any other portion.

Does a ripe frozen blackberries have more calories?

Barely. As fruit ripens, starch converts to sugar — same calories, different molecule. What changes: sweeter taste, faster blood-sugar rise, softer texture. Total calories move maybe 3–5%.

Is frozen blackberries actually healthy, or is that marketing?

By the numbers on this page: fiber, vitamin C, potassium; sugar comes with its brake pedal (fiber).
