For one mixed drink alongside a ploughman’s lunch, a 150ml mixer is a useful starting point: Sainsbury’s lists Fever-Tree’s suggested serve as 50ml spirit with 150ml tonic. Choose a 200ml portion if you want more mixer, and compare standard and lower-calorie tonic by the ingredients and nutrition on the exact pack rather than assuming they taste the same.
A 150ml portion lets you open a mixer for each drink without leaving part of a large bottle after lunch. Sainsbury’s lists Fever-Tree in an 8 × 150ml pack, while Tesco Groceries lists Schweppes 150ml multipacks.
Standard and lower-calorie tonic are both available in 150ml formats. Compare the exact pack’s nutrition and ingredients, including sweeteners, rather than treating the versions as interchangeable.
If the drink will stand alone beside cheese, bread and pickle, decide whether you want tonic’s quinine flavour or a soda, ginger drink or other sparkling option. Fever-Tree lists these different drink types, and Fentimans has described a 200ml mixer range spanning tonic, soda water and ginger ale.
Decide how much mixer you want in the glass, then choose the drink type and check the formulation on the pack you intend to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare the volume per container, not just the multipack count. Sainsbury’s gives Fever-Tree’s suggested mixed serve as 50ml spirit plus 150ml tonic; a 200ml container holds more mixer than that serve. | I want one portion for each drink without leaving an opened large bottle. If I prefer more mixer, I would choose the larger portion deliberately. |
| Drink type | Check whether the product is tonic, soda water, ginger ale or another soft drink. Tesco Groceries describes its Schweppes tonic as containing quinine; Fentimans has listed tonic, soda water and ginger ale in its 200ml range. | For a drink on its own, I would choose the flavour I want alongside lunch rather than assume it needs to be tonic. |
| Formulation | Compare the current nutrition panel and ingredient list for sugars and sweeteners. Sainsbury’s describes Fever-Tree Refreshingly Light Premium Indian Tonic as having 50% fewer calories than its standard Premium Indian Tonic; Tesco Groceries lists Schweppes Slimline as a low-calorie tonic with sweetener. | If I am considering a lower-calorie tonic, its ingredients and flavour matter to me as well as its label description. |
| Pack details | Confirm whether the individual containers are cans or bottles if that affects serving or storage. Read the exact pack’s ingredients and nutrition information, since product details can change. | I want the container format I expect and a current label I can use to compare products. |
Sainsbury’s gives Fever-Tree’s suggested serve as 50ml spirit with 150ml tonic. A 200ml portion is larger, so using all of it changes the amount of mixer in the glass.
Decide on the drink size before choosing between 150ml and 200ml containers.
Lower-calorie versions can have different ingredients. Tesco Groceries identifies sweetener in Schweppes Slimline, while Sainsbury’s describes Fever-Tree’s Refreshingly Light tonic in comparison with its standard version.
Compare the exact ingredient lists and nutrition panels, and try the formulation before committing to a larger multipack if flavour is important to you.
Tonic contains quinine and has a different flavour role from soda water or ginger ale. That distinction matters when there is no spirit in the glass.
Choose the drink type you want alongside the meal rather than defaulting to tonic because it is labelled a mixer.
Product ingredients can change. A previous description may not reflect the pack being sold when you shop.
Check the current pack’s ingredient list and nutrition panel, particularly when comparing sugars, sweeteners or dietary declarations.
Its range includes tonics, sodas and ginger drinks; Sainsbury’s lists its Premium Indian Tonic in an 8 × 150ml pack.

These tonic multipacks offer 150ml portions for one drink or 200ml portions if you want more mixer. Check each listing for the container format where that matters to you.

It matches the mixer quantity in Fever-Tree’s suggested serve of 50ml spirit and 150ml tonic, as listed by Sainsbury’s. If you want more mixer or are drinking tonic on its own, choose the portion size for the drink you intend to make.
Choose by comparing the exact packs’ nutrition, ingredients and flavour. Sainsbury’s says Fever-Tree Refreshingly Light Premium Indian Tonic has 50% fewer calories than its standard Premium Indian Tonic; Tesco Groceries describes Schweppes Slimline as a low-calorie tonic with sweetener. Neither description means the formulations taste the same.
Yes. Schweppes describes its tonic as a drink to mix or enjoy on its own. If tonic’s quinine flavour is not what you want, compare it with soda water, ginger drinks or other sparkling soft drinks instead.
Check the exact pack’s ingredients and nutrition panel, including sugars and sweeteners if you are comparing tonic formulations. The NHS explains that nutrition information is usually on the back or side of pre-packed products, and ingredients may change from those shown in an older listing.
Start with the amount you want in the glass: 150ml matches Fever-Tree’s suggested mixer quantity for its 50ml-spirit serve, while 200ml provides a larger mixer portion. Also confirm whether the product is tonic or another drink type, and whether its individual containers are cans or bottles if that affects your choice.
