Hosts serving one drink at a time
Individual cans let you open mixer as each drink is made. The examples listed by Tesco Groceries include Fever-Tree 8 × 150ml and Schweppes 12 × 150ml tonic packs.
Who are these cans for?
Shoppers comparing tonic ingredients
“Slimline” and “light” do not describe the same sugar content across products. Tesco Groceries lists 0g sugars per 150ml for Schweppes Slimline and 3.8g per 100ml for Fever-Tree Refreshingly Light.
Hosts making alcohol-free drinks
Choose between tonic’s quinine flavour and a plainer soda-water mixer according to the drink you intend to serve. The Britvic soda water listed by Amazon UK contains carbonated water and sodium carbonate.
What should you check?
Start with the flavour the drink needs, then match the can size and ingredients to the number and type of serves you plan to make.
| Priority | What to check | Your needs |
|---|---|---|
| Mixer flavour | Check whether the ingredients list quinine. For a plainer alternative, Britvic Soda Water’s Amazon UK listing gives carbonated water and sodium carbonate as its ingredients. | I want tonic’s bitter flavour in the drink, or I only need carbonation alongside the other ingredients. |
| Sugars and sweeteners | Read sugars per serving or per 100ml alongside the sweetener ingredients. Tesco Groceries lists Schweppes Slimline at 0g sugars per 150ml with aspartame; Fever-Tree Refreshingly Light lists 3.8g per 100ml and no artificial sweeteners. | If I want a zero-sugar tonic, a light tonic that still contains sugar will not meet that requirement. If I avoid a particular sweetener, I need to check the label too. |
| Can size | Match the can to the volume used in each drink. Tesco Groceries lists 150ml Fever-Tree and Schweppes tonic cans, alongside Tesco Low Calorie Indian Tonic Water in 250ml cans. | Will I use a whole 150ml can for each drink, or does my planned serve call for 250ml? |
| Pack quantity | Check both can count and total volume: eight 150ml cans contain 1.2 litres, while six 250ml cans contain 1.5 litres. | I need enough individual cans for the drinks I plan to make, not simply the largest total volume. |
Common buying mistakes
-
Assuming every light tonic is sugar-free
Tesco Groceries lists 0g sugars per 150ml can for Schweppes Slimline, but 3.8g sugars per 100ml for Fever-Tree Refreshingly Light.
Read the sugars figure and ingredient list on the product you intend to serve; do not use “light” as a substitute for either check.
-
Choosing by can count alone
Six 250ml cans provide more total mixer than eight 150ml cans, but fewer individually sealed portions.
Plan how many drinks you will make and how much mixer each will use before choosing a pack format.
-
Buying tonic when the drink only needs fizz
The tonic examples list quinine, whereas the Britvic soda water listed by Amazon UK contains carbonated water and sodium carbonate.
Choose soda water if you do not want tonic’s flavour in the finished drink.
-
Using a drink count to make a driving decision
If alcohol is added, the mixer does not remove it. GOV.UK says there is no universal number of drinks that corresponds to the drink-drive limit; the limits also differ between Scotland and the rest of the UK.
If driving is planned, serve an alcohol-free option or arrange alternative transport rather than relying on a drink-count rule.

Frequently asked questions
Is a 150ml or 250ml can more practical for breakfast drinks?
Choose 150ml when each drink will use that amount of mixer; choose 250ml when the planned drink needs the larger volume. Tesco Groceries lists Fever-Tree and Schweppes tonic in 150ml cans and Tesco Low Calorie Indian Tonic Water in 250ml cans.
Is light tonic sugar-free?
Not necessarily. Tesco Groceries lists 0g sugars per 150ml can for Schweppes Slimline, while Fever-Tree Refreshingly Light lists 3.8g per 100ml. Read the sugars figure and sweetener ingredients for the specific tonic you are buying.
When should I choose soda water instead of tonic?
Choose soda water when the drink needs carbonation without tonic’s quinine flavour. The Britvic Soda Water listed by Amazon UK contains carbonated water and sodium carbonate; the sampled tonic ingredient lists include quinine.
Should I check the can label before serving?
Yes, particularly if an ingredient, allergen or sweetener matters to someone you are serving. Check the label on the actual can so the decision reflects the product in hand.
If I add alcohol, is there a safe number of drinks before driving?
Do not use a fixed drink count to decide whether to drive. GOV.UK says the number of drinks corresponding to the drink-drive limit differs by person, and the limits in Scotland differ from those in the rest of the UK. Serve an alcohol-free drink or arrange alternative transport if driving is planned.
