Choose a 150ml tonic can if you want a smaller, individually portioned mixer for a TV-night drink; choose a 200ml Fentimans bottle if that larger serve suits what you plan to pour. Size does not settle the recipe: compare the exact product’s sugars, calories, sweeteners and ingredients before choosing standard, light or zero-sugar tonic.
The useful starting point is how much mixer you intend to pour, followed by the recipe and flavour you want alongside your snacks.
An individually portioned mixer lets you choose a can or bottle close to your intended serve instead of opening a larger mixer bottle. Tesco Groceries lists 150ml Fever-Tree and Schweppes cans, while Fentimans describes a 200ml mixer range.
“Slimline” and “light” do not describe identical ingredients. Sainsbury’s lists 0g sugars per 150ml for Schweppes Slimline, which contains aspartame; Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian.
Fever-Tree lists Indian, Mediterranean and fruit-led tonics, while Fentimans describes citrus and botanical ingredients in its tonic range. Choose the flavour profile for the drink you have in mind, then check the individual product’s size and ingredients.
Decide on the volume of one serve first. Then compare nutrition on the same per-100ml basis as well as for the whole can or bottle.
| Priority | What to check | Your needs |
|---|---|---|
| Serve size and pack | Check the volume of each unit, its container type and the number in the pack. Tesco Groceries lists Fever-Tree and Schweppes 150ml can multipacks; Fentimans describes 200ml mixers. | I would use a smaller pour for one drink, or a 200ml bottle for a larger serve. The pack should also contain a suitable number of portions for the people and TV nights I have planned. |
| Sugars and calories | Compare both figures per 100ml and per intended serve. Sainsbury’s lists 0g sugars and 3kcal per 150ml for Schweppes Slimline, against 7.4g sugars and 32kcal per 150ml for its standard Schweppes tonic. | If I want zero sugar, I need to check the actual nutrition panel rather than assume a product labelled “light” has none. I also want to know what a full can or bottle contains. |
| Flavour | Look beyond “tonic” to the named variant and ingredients. Fever-Tree lists several tonic styles; Fentimans describes lemon oil, lemongrass and other botanical ingredients in its Premium Indian tonic. | For a mixed drink, I want a flavour profile that suits what I am making, rather than choosing by pack size alone. |
| Ingredients | Read the exact product label for quinine, sweeteners and any accompanying statements. Joybuy lists aspartame and quinine for Schweppes Slimline and states that it contains a source of phenylalanine. | Someone drinking it may avoid a particular ingredient, so I need to check the specific recipe before serving it. |
The recipes differ. Sainsbury’s lists 0g sugars per 150ml for Schweppes Slimline, whereas Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian; Fentimans lists 3.4g per 100ml for Naturally Light.
Check sugars, calories and sweeteners for the exact variant, using both the per-100ml figures and the amount you expect to pour.
The tonic products described by Schweppes and Fentimans list quinine. Schweppes Slimline also lists aspartame and carries a statement that it contains a source of phenylalanine.
Read the ingredients and accompanying label statements on the pack you intend to serve, particularly when someone needs to avoid an ingredient.
Tesco Groceries lists 150ml tonic cans, while Fentimans describes a 200ml mixer-bottle range. Searching only for bottles can leave out a smaller individually portioned format.
Compare 150ml cans with 200ml bottles according to your intended pour, then confirm the container and pack count on the chosen product.

The title identifies eight 150ml portions for drinks across multiple occasions. If you specifically need cans rather than bottles, confirm the individual container type before buying; also check the exact pack’s nutrition and ingredients rather than assuming “Naturally Light” means sugar-free.
Choose the format that fits the mixer amount you intend to pour: Tesco Groceries lists 150ml Fever-Tree and Schweppes cans, while Fentimans describes 200ml mixers. A larger bottle also gives you a different portion size, so check both the volume and the recipe rather than choosing on flavour alone.
No. Joybuy lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Premium Indian, and Fentimans lists 3.4g per 100ml for Naturally Light. By contrast, Sainsbury’s lists 0g sugars per 150ml for Schweppes Slimline, which contains aspartame. Check the exact nutrition and ingredients panels.
Start with the volume of each unit, pack count, sugars and calories, then read the ingredients for quinine or sweeteners. If you are considering Schweppes Slimline, its product information also states that it contains a source of phenylalanine; check the statement on the pack intended for the drinker.
