Most incorrect calculations begin with the wrong column, the wrong product variant or a concentrate value entered as though it described the prepared drink.
Find “carbohydrate—of which sugars”
UK back-of-pack nutrition declarations list carbohydrate and sugars separately. For SlushWise, use the row labelled “of which sugars” or simply “sugars”. Do not use total carbohydrate: that broader number can include starch and other carbohydrate that is not reported as sugar.
Do not use a front-of-pack percentage, calories, or the number of grams in the whole bottle. The calculator expects a concentration in grams of sugars per 100 ml.
Choose the per-100 ml column
A label may show values “per 100 ml”, “per serving” and “per bottle” side by side. The per-serving figure changes with the manufacturer’s chosen serving size. The per-100 ml figure is standardised, which lets SlushWise scale it to any batch volume.
If a 500 ml bottle contains 22.5 g of sugar in total, its concentration is 4.5 g per 100 ml. Enter 4.5, not 22.5. SlushWise multiplies the concentration by the batch size itself.
For squash or concentrate, use the prepared-drink value
Concentrated squash is intended to be diluted. Its concentrate may show a very high sugar value that no longer describes the liquid after water is added. Look for nutrition information “as prepared” using the stated dilution, or calculate the finished concentration from reliable label instructions.
Do not assume everybody uses the same dilution. If you make a stronger or weaker drink than the label’s example, the prepared sugar concentration changes too. Measure consistently and document the dilution if you submit a community result.
Millilitres of finished drink and grams of sugar per 100 ml must both describe the same prepared mixture.
Match the exact flavour and formulation
“Original”, “Zero”, “Diet”, “No Added Sugar” and “Reduced Sugar” are not interchangeable. Two bottles with similar branding can have very different sugar values. Flavours can differ, and manufacturers can reformulate a product while keeping a familiar name.
- Match the complete product name and flavour.
- Check whether the bottle is regular, diet, zero or another variant.
- Prefer your current bottle over an old web listing.
- Check the country, because formulations can vary between markets.
- Use the barcode search as a shortcut, then verify the displayed sugar against the physical label.
Labels and databases have limits
Nutrition values may be rounded, recipes can change, and community databases can contain outdated entries. A displayed 4.5 g per 100 ml is not laboratory precision to unlimited decimal places. That is why SlushWise rounds a positive correction up to the next whole gram and repeatedly asks you to verify the bottle.
If the label conflicts with a SlushWise guide, use the bottle in front of you and report the correction. Product pages display their source and verification status so a calculated result is not mistaken for an independently tested recipe.
