Family snack planners comparing sugar
For drinks alongside half-term snacks, check the amount of sugar per serving rather than assuming every mixer described as light has the same sugar content.
Who is choosing these mixers?
Zero-sugar tonic buyers
If 0g listed sugars per 100ml is the deciding requirement, compare that figure on the nutrition panel and read the ingredient and safety labels for the intended drinker.
Shoppers considering light botanical tonics
A light tonic may still fit when its particular formulation matters more than a zero-sugar requirement. Check the sugar figure before choosing it for a snack occasion.
What should you check first?
Compare sugar on the same per-100ml basis first, then check ingredients and pack size against how the drinks will be served.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar content | Read sugars per 100ml and the serving volume. Schweppes Slimline lists 0g sugars per 100ml; Fever-Tree Refreshingly Light Indian Tonic lists 3.8g. | I want to know how much sugar is in the drink served with snacks, not rely on “diet” or “light” on the front of the pack. |
| Light or standard | Compare energy and sugars per 100ml on the exact light and standard products. A reduced-calorie description does not mean zero sugar. | If some sugar is acceptable, I can compare the light mixer with the standard one I would otherwise buy. |
| Ingredients | Read the sweetener list and any phenylalanine declaration on the current pack. Schweppes Slimline product information lists aspartame and a source of phenylalanine. | Before serving a sweetened tonic, I want to check whether its ingredients or label warnings matter to anyone drinking it. |
| Pack and storage | Compare the volume of each serving and the number of bottles or cans. Follow the product’s instructions after opening; Sainsbury’s says to refrigerate its Diet Indian Tonic and use it within 3 days. | Smaller individual serves may suit a brief snack occasion; a large bottle makes more sense if it can be used within its stated storage period. |
What is easy to overlook?
-
Reading “light” as “zero sugar”
Fever-Tree Refreshingly Light Indian Tonic lists 3.8g sugars per 100ml, and Fentimans Naturally Light lists 3.4g, according to their product information. Neither figure is 0g.
Compare the nutrition panels per 100ml, then calculate what the stated serving volume means for the drink you will pour.
-
Skipping the sweetener declaration
Schweppes Slimline and Britvic Low Calorie Indian Tonic product information declares a source of phenylalanine.
Read the ingredient and safety information on the exact pack, particularly if a declaration is relevant to the intended drinker.
-
Opening more than you will use
Sainsbury’s says its 1L Diet Indian Tonic should be refrigerated after opening and used within 3 days.
Check the storage instruction before choosing between a large bottle and individual cans for a short snack occasion.

Common questions
Does “light” or “diet” tonic always mean zero sugar?
No. Tesco Groceries lists 0g sugars per 100ml for Schweppes Slimline, while Joybuy product information lists 3.8g for Fever-Tree Refreshingly Light Indian Tonic and Fentimans lists 3.4g for Naturally Light. Read the sugars figure on the exact product rather than relying on its name.
Why do some diet tonics declare phenylalanine?
The declaration appears on the aspartame-containing Schweppes Slimline and Britvic Low Calorie Indian Tonic product information. Check the current ingredient and safety label if it matters to the intended drinker.
What should I check for drinks served with children’s half-term snacks?
Compare the sugars figure and the amount you plan to serve, including for products described as light. The NHS advises limiting foods and drinks containing free sugars; the nutrition panel lets you compare the drinks you are considering without assuming a light mixer is sugar-free.
How long can an opened 1L diet tonic be kept?
Sainsbury’s says to refrigerate its Diet Indian Tonic after opening and use it within 3 days. Follow the instruction on the specific bottle you buy, as storage directions can differ.
