One-drink top-up shoppers
If you want to open only the mixer you will pour, a 150ml can matches Fever-Tree’s stated 50ml spirit and 150ml mixer serve. Tesco Groceries lists 150ml tonic multipacks from both Fever-Tree and Schweppes.
Choose a 150ml can if you want one measured mixed drink: Fever-Tree gives a serving guide of 50ml spirit with 150ml mixer, and Schweppes also offers 150ml tonic packs. A 200ml Fentimans bottle suits a larger pour or a preference for glass and its herbal, citrus-led tonic; whichever format you choose, check the specific recipe if sugars or sweeteners matter to you.

A small portion does not tell you how much sugar it contains. The Joybuy listing for Fever-Tree Naturally Light gives 3.8g sugars per 100ml, while Tesco Groceries lists 0g sugars per 250ml can for its Low Calorie Indian Tonic Water; the can sizes differ too.
Fentimans says it moved its mixer range from 125ml to 200ml. It describes its Premium Indian Tonic Water with herbal infusions, Sicilian lemon oil and lemongrass extract, giving you a specific flavour profile to consider alongside the larger pour.
Start with the amount of mixer you plan to use, then compare the recipe and container format rather than treating every small tonic as the same serve.
| Priority | What to check | Your needs |
|---|---|---|
| Pour size | Compare 150ml cans with 200ml bottles and larger cans. Fever-Tree’s serving guide pairs 150ml mixer with 50ml spirit; another volume changes that stated ratio. | I want to open just enough mixer for the drink I plan to make, rather than leave part of a container open. |
| Sugars and sweeteners | Read the ingredients and nutrition per 100ml as well as per container. Joybuy lists 3.8g sugars per 100ml for Fever-Tree Naturally Light; Tesco Groceries lists 0g sugars per 250ml can for Tesco Low Calorie Indian Tonic Water, which contains sucralose and acesulfame K. | A light-sounding name is not enough for me: I want to know which sugars or sweeteners are in the particular tonic. |
| Flavour | Check the named tonic variant and its ingredients. Fentimans describes herbal infusions, Sicilian lemon oil and lemongrass extract in its Premium Indian Tonic Water. | If I am choosing a botanical tonic, I want its stated flavours to suit the drink I have in mind. |
| Container and pack | Check whether the listing specifies cans or glass bottles, the volume of each container and the number in the pack. Do not assume that a 200ml bottle serves the same pour as a 150ml can. | For a quick top-up, I need a container size and pack count that fit the drinks I intend to make. |
A 200ml bottle or 250ml can contains more mixer than Fever-Tree’s stated 150ml pour with 50ml spirit. Using the whole container would not reproduce that ratio.
Decide how much mixer you want in the glass before choosing a container size; keep any remainder in mind if you do not plan to use it at once.
The Joybuy listing for Fever-Tree Naturally Light states 3.8g sugars per 100ml. Tesco Groceries lists 0g sugars per 250ml can for its Low Calorie Indian Tonic Water and names sucralose and acesulfame K in the ingredients.

It matches Fever-Tree’s stated serve of 50ml spirit with 150ml mixer. If you prefer a different balance, choose the mixer volume for that drink rather than treating 150ml as a rule for every recipe.
Choose a 150ml can for a pour that matches Fever-Tree’s stated single-drink mixer measure. Consider a 200ml Fentimans bottle if you prefer that format or want a larger pour; the two volumes are not interchangeable in the same recipe.
