For a refillable lecture bottle, Robinsons Orange offers a 1:4 dilution instruction and a labelled 3 kcal and 0 g sugars per 250 ml prepared drink. Tesco Quadruple Strength Blackcurrant is worth considering if stated serving yield matters more: its label gives 100 servings, but its 1:19 ratio calls for more careful measuring. If flavour or sweetener choice leads your decision, compare the exact recipe and nutrition after dilution before buying.
Who is this for?
Students carrying a refillable bottle
A concentrate lets you mix a drink with water rather than carry several ready-to-drink bottles. Compare the mixing instructions with where you will prepare it: Tesco Groceries lists a 1:4 ratio for Robinsons Orange and a 1:19 ratio for Tesco Quadruple Strength Blackcurrant.
Students choosing no added sugar
Check the nutrition for the drink after dilution, not just the wording on the front of the bottle. No added sugar does not mean that every prepared drink has the same sugar or calorie values.
Buyers checking ingredients
Sweeteners and declared allergens can differ between flavours and strengths, even within one brand. If an ingredient matters to you, use the declaration on the exact bottle you intend to buy.
What matters when choosing?
Start with the flavour and mixing routine you want for lunch, then compare prepared-drink nutrition and the exact ingredient list.
| Priority | What to check | Your needs |
| Prepared drink |
Check that the product is labelled no added sugar. Compare calories and sugars using the stated diluted serving size, rather than the concentrate alone. |
I want a flavoured lunch drink without added sugar, while knowing what is in the glass I actually drink. |
| Mixing |
Read the water-to-concentrate ratio and any stated serving yield. Tesco Groceries lists Robinsons Orange at 1:4 and Tesco Quadruple Strength Blackcurrant at 1:19, with 100 stated servings for the latter. |
For a quick refill between lectures, I would rather use a ratio I can measure consistently than choose by bottle yield alone. |
| Ingredients |
Read the sweetener list, allergen declaration and any phenylalanine warning on the exact flavour and strength. Tesco Groceries lists aspartame and a phenylalanine warning for Robinsons Double Concentrate Orange. |
A familiar brand name is not enough if I need to avoid a particular ingredient. |
| Flavour |
Compare orange, blackcurrant, lime and lemon-and-lime recipes alongside their dilution instructions. Sainsbury's lists Belvoir Farm Sicilian Lemon & Lime at 1:6. |
If I prefer citrus to berry flavours, I still want a recipe I can mix easily for lunch. |
Common buying mistakes
-
Assuming no added sugar means zero sugars in the drink
The label describes added sugar, not necessarily all sugars present after dilution. Tesco Groceries lists 0 g sugars per 250 ml diluted serving for Robinsons Orange, while its Vimto No Added Sugar listing gives 0.8 g per 250 ml.
Compare the nutrition panel at the prepared serving size and follow the bottle's dilution instructions.
-
Assuming every flavour has the same ingredients
Recipes can differ across a range. Tesco Groceries lists aspartame and a phenylalanine warning for Robinsons Double Concentrate Orange; those details should not be applied to the separate standard-strength Orange product.
Check the exact bottle for sweeteners, allergens and warnings, particularly when an ingredient affects your choice.
-
Choosing a concentrated bottle by serving yield alone
Tesco Quadruple Strength Blackcurrant states 100 servings, but its 1:19 mixing ratio needs measuring differently from a 1:4 squash.
Consider where you will mix your lecture drink and whether you can follow the stated ratio each time.
Brand and product-line references
These examples describe specific listed recipes, not every product made by each brand or what Joybuy stocks.
Robinsons
The standard-strength Orange No Added Sugar Squash and Double Concentrate Orange have different listed recipes.
- Tesco Groceries lists a 1:4 ratio and 3 kcal with 0 g sugars per 250 ml diluted serving for standard-strength Orange.
- Its Double Concentrate Orange listing names aspartame and carries a phenylalanine warning; check the strength as well as the flavour.
Tesco
Its own-label Quadruple Strength Blackcurrant No Added Sugar Squash is a more concentrated mixing option.
- Tesco Groceries states 100 servings and a 1:19 dilution ratio for the 1.5 L bottle.
- That ratio calls for attention when measuring a single drink.
Sainsbury's
Its listed 1 L No Added Sugar Lime Cordial provides a lime option.
- Sainsbury's describes the cordial as containing 30% fruit juice from concentrate and instructs dilution at 1:4.
- Check its prepared-drink nutrition and ingredients if either affects your choice.
Belvoir Farm
Sicilian Lemon & Lime No Added Sugar Cordial is a citrus recipe sweetened with stevia.
- The Sainsbury's listing states 14 servings from a 500 ml bottle and a 1:6 dilution ratio.
- Check the retailer's current availability if this particular recipe is your preference.
Vimto
Its listed No Added Sugar Squash has a grape, blackcurrant and raspberry flavour profile.
- Tesco Groceries lists 0.8 g sugars per 250 ml prepared serving.
- Check the precise ingredients on the bottle if you avoid particular sweeteners or allergens.

Questions about choosing and mixing
Does no added sugar mean the prepared drink has zero sugars?
No. Fruit ingredients can contribute sugars even when none has been added. Tesco Groceries lists 0 g sugars per 250 ml diluted serving for Robinsons Orange and 0.8 g per 250 ml for Vimto No Added Sugar Squash, so compare the prepared-drink nutrition on each product.
Should I choose the bottle with the most servings?
Only if its mixing routine suits you. Tesco Groceries states 100 servings and a 1:19 dilution ratio for Tesco Quadruple Strength Blackcurrant; Robinsons Orange uses a 1:4 ratio. Consider how you will measure concentrate when filling your lecture bottle.
What should someone with PKU check on a squash label?
Check the exact product for aspartame and a phenylalanine warning. Tesco Groceries lists both aspartame and a “Contains a Source of Phenylalanine” warning for Robinsons Double Concentrate Orange; do not assume a different flavour or strength has the same ingredients.
How do I mix cordial for a lecture lunch?
Follow the ratio on the bottle you buy. The listed ratios vary: Tesco Groceries gives 1 part Robinsons Orange to 4 parts water and 1 part Tesco Quadruple Strength Blackcurrant to 19 parts water, while Sainsbury's lists Belvoir Farm Sicilian Lemon & Lime at 1:6.
