Gym-goers carrying a refillable bottle
If you can add concentrate to water at the gym, a small format avoids packing a full-size cordial bottle. Robinsons describes its Summer Fruits Mini as a concentrate squeezed into a water bottle on the go.
Who is this choice for?
People swapping sugary drinks
If you want a diet or no-added-sugar alternative, compare the drink as prepared, not just the wording on the bottle. The NHS suggests diet, sugar-free or no-added-sugar drinks as swaps for sugary drinks.
People planning longer or harder sessions
A low-sugar squash can flavour water, but it should not be treated as exercise fuel. The British Nutrition Foundation says dietary needs vary with the amount and intensity of activity, and identifies carbohydrate as a fuel used during exercise.
What should you check?
Decide where you will mix the drink first, then compare prepared-drink labels and ingredients; if the session calls for fuelling, consider that separately from your choice of drink flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Portability | Check bottle size, whether the concentrate is intended for use in a water bottle, and whether water will be available. Robinsons states that a 3.3ml serving of Summer Fruits Mini is added to 250ml water. | I want to flavour my refillable bottle without carrying a full-size cordial bottle. |
| Prepared-drink nutrition | Use the stated dilution instructions and compare energy and sugars for the same volume of prepared drink. Tesco lists 6kcal and 0.2g sugars per prepared 250ml serving of its Lime Cordial; Sainsbury's lists 13kcal and less than 0.5g sugars for its own lime option. | If I'm swapping a sugary drink, I want to know what is in the glass I actually drink, not just the concentrate. |
| Ingredients | Read the current ingredient and allergen declaration. The cited Robinsons Mini, Tesco, Sainsbury's and Waitrose examples list sweeteners and sulphites or sodium metabisulphite. | Some ingredients may affect which bottle I choose, even when it says no added sugar. |
| Exercise fuelling | Keep drink flavour separate from carbohydrate planning. The British Nutrition Foundation says exercise-related dietary needs depend on activity amount and intensity; the NHS recommends water for replacing fluid lost through physical activity. | For a longer or harder session, I need to think about food as well as what to put in my water bottle. |
Common buying mistakes
-
Reading “no added sugar” as “zero sugar”
Waitrose says its No Added Sugar Lime Juice Cordial contains naturally occurring sugars and lists less than 0.5g sugars per prepared 250ml serving. The front-label wording does not give you the prepared drink's sugar figure.
Check the nutrition panel for the drink at its stated dilution.
-
Comparing concentrate with a diluted drink
Marks & Spencer lists sugars per 100g of its Sicilian Lemon and Mexican Lime cordial, while the cited no-added-sugar options provide prepared-drink figures. Those numbers describe different products and serving bases.
Follow each bottle's dilution instructions and compare equal volumes of prepared drink where the labels allow it.
-
Using a low-sugar cordial as workout fuel
Flavouring water does not make a no-added-sugar cordial a substantial carbohydrate source. The British Nutrition Foundation says carbohydrate is a fuel during exercise and that dietary needs vary with activity amount and intensity.
Consider food and drink as separate parts of your plan for a demanding session.
-
Overlooking sweeteners and sulphites
The cited Robinsons, Tesco, Sainsbury's and Waitrose no-added-sugar examples list sweeteners and sulphites or sodium metabisulphite. A diet-oriented label does not tell you whether the ingredients suit you.
Read the ingredient and allergen declaration on the pack you are buying.
Brand and retailer ranges to compare
Compare particular formats and recipes rather than assuming every cordial from a brand has the same sugar content or pack size.
Robinsons
Its no-added-sugar Mini squash is a portable concentrate intended to be added to water in a bottle.
- Robinsons states that Summer Fruits Mini provides 20 servings, with 3.3ml added to 250ml water per serving.
- Robinsons also identifies its classic Barley Waters and Cordials as ranges with added sugar. Check the exact product rather than relying on the brand name.
Tesco
Tesco Lime Cordial is a 1L no-added-sugar concentrate for mixing with water.
- Tesco lists 6kcal and 0.2g sugars per prepared 250ml glass.
- Its ingredient list includes sucralose, acesulfame K and sodium metabisulphite; the 1L bottle is larger than a Mini concentrate.
Sainsbury's
Its 1L Lime Cordial No Added Sugar has a stated dilution of one part cordial to four parts water.
- Sainsbury's lists 13kcal and less than 0.5g sugars per prepared 250ml serving.
- The ingredients list includes sucralose and sulphites; consider the full-size bottle if you plan to carry it.
Waitrose
Waitrose No Added Sugar Lime Juice Cordial is a 1L concentrate with a suggested one-to-four dilution.
- Waitrose lists 6kcal and less than 0.5g sugars per prepared 250ml serving.
- It contains naturally occurring sugars and lists sucralose and sodium metabisulphite among its ingredients.
M&S
Its Sicilian Lemon and Mexican Lime Cordial is a regular cordial containing sugar.
- Marks & Spencer identifies lemon juice from concentrate in the recipe.
- The listed 4.9g sugars per 100g is for the cordial, not a prepared serving; do not compare it directly with diluted-drink figures.

Frequently asked questions
Does no added sugar mean a cordial contains no sugar?
No. Waitrose says its No Added Sugar Lime Juice Cordial contains naturally occurring sugars and lists less than 0.5g sugars per prepared 250ml serving. Read the prepared-drink nutrition panel rather than treating “no added sugar” as “zero sugar”.
Should I choose water or no-added-sugar squash after the gym?
The NHS recommends water for replacing fluid lost through physical activity. If you prefer a flavoured drink, a no-added-sugar squash diluted as directed is an option; do not expect it to provide a special recovery benefit.
Can a low-sugar cordial fuel a long or hard workout?
Do not rely on it as your carbohydrate source. The British Nutrition Foundation says carbohydrate is a fuel during exercise and dietary needs vary with activity amount and intensity, so consider food separately from a drink used to flavour water.
What if I avoid certain sweeteners or sulphites?
Check the current pack's ingredients and allergen declaration before choosing. The cited Robinsons Mini, Tesco Lime, Sainsbury's Lime and Waitrose Lime products list sweeteners and sulphites or sodium metabisulphite.
How can I compare cordial nutrition fairly?
Compare equal volumes of drink prepared according to each maker's dilution instructions. For example, Marks & Spencer gives a sugar figure for its undiluted Sicilian Lemon and Mexican Lime cordial, which is not directly comparable with the prepared-serving figures for the cited no-added-sugar options.
