For one drink with train food, a 150ml tonic can gives you a smaller portion than the 200ml and 330ml formats considered here. If you prefer a bottle, check whether a 200ml portion suits you; whichever format you choose, compare the sugar and ingredient labels rather than assuming that a tonic described as light is sugar-free.
A small, unopened tonic portion may be easier to plan around than opening a larger bottle for one drink. Tesco Groceries lists Schweppes Slimline in 150ml cans, while Fentimans lists its Naturally Light tonic in 200ml bottles.
Small tonics can differ in sugar content. Tesco Groceries lists 0g sugars per 150ml serving for Schweppes Slimline; the Joybuy listing for Fever-Tree Refreshingly Light Premium Indian Tonic lists 3.8g sugars per 100ml.
Read the exact pack if quinine or sweeteners matter to you. The tonic product information considered here lists quinine, and ASDA Groceries lists aspartame and a source of phenylalanine for Schweppes Slimline.
Start with the portion and container you want to carry, then compare the nutrition and ingredient labels of products that fit.
| Priority | What to check | Your needs |
|---|---|---|
| Portion and container | Compare the volume of each unit, not just the multipack total. Check whether it is a can or bottle and whether you need to close it again after opening. | I want one small portion with my food, without carrying an opened larger bottle for the rest of the journey. |
| Sugar and energy | Compare figures on the same basis: per 100ml or per serving. Tesco Groceries lists Schweppes Slimline at 0g sugars and 3kcal per 150ml; Joybuy lists Fever-Tree Refreshingly Light Premium Indian Tonic at 3.8g sugars and 15kcal per 100ml. | If zero sugar matters to me, I will check the stated sugar figure rather than relying on the word ‘light’. |
| Ingredients | Read the current label for quinine and sweeteners. ASDA Groceries lists aspartame and a source of phenylalanine for Schweppes Slimline; Joybuy lists fructose in Fever-Tree Refreshingly Light Premium Indian Tonic. | I need to know what is in the exact tonic I am packing, particularly if I avoid a listed ingredient. |
| Tonic style | Compare the named ingredients rather than assuming tonics have the same flavour. Fentimans describes lemongrass, kaffir lime leaves and juniper in its Naturally Light tonic, which comes in a 200ml format. | I may want a tonic with named botanicals alongside my food, provided the larger portion still suits the journey. |
Schweppes Slimline is listed by Tesco Groceries at 0g sugars per 150ml, but Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian Tonic.
Use the nutrition panel to distinguish a zero-sugar tonic from a sweetened one, and compare serving sizes before comparing figures.

For a single drink with train food, check the volume of one can; a larger format may suit you if you intend to share it.

Check the current pack before buying if you avoid a particular ingredient. If an ingredient raises a medical concern for you, seek personalised advice from an appropriate healthcare professional.
