What is Brix? The Standard of Juice Concentration
Brix (°Bx) is a measurement of soluble solids in a liquid. In fruit juice and juice concentrate, those soluble solids include naturally occurring sugars along with acids and other dissolved material.
FruitFast uses fruit-specific Brix targets as a practical way to monitor concentration and batch consistency.
The Short Answer
Brix measures concentration—not nutritional potency. A higher Brix does not prove that a juice contains more anthocyanins, vitamins, minerals or other individual compounds.
What Does 65 °Brix Mean?
A reading near 65 °Brix means the liquid contains a high level of dissolved soluble solids relative to water. It does not mean the product is 65% added sugar.
Different fruits naturally have different sugar, acid and solids profiles, so FruitFast does not use one universal Brix target for every concentrate.
Why FruitFast Uses Brix
- Monitor concentration from batch to batch.
- Help maintain consistent flavor and mixing strength.
- Confirm that a concentrate has reached its intended soluble-solids range.
- Provide a useful technical reference for commercial and culinary users.
Typical FruitFast Concentrates
Many FruitFast concentrates are produced around the mid-60s to upper-60s °Brix range, while certain fruits use different targets. Lemon concentrate is typically described by citric-acid strength rather than a standard fruit Brix target.
Brix & Mixing
A high-Brix concentrate is meant to be diluted or used in smaller quantities. See the Reconstitution Guide for practical mixing ideas.
