Hosts planning individual mixer serves
A 12 × 150ml case gives you twelve unopened portions to use across the occasion. The number of finished drinks still depends on how much mixer each recipe calls for.
Who is a case of 12 for?
Shoppers comparing sugar and sweeteners
Tesco Groceries lists 7.4g sugars per 150ml for Schweppes regular tonic and 0g for Slimline. Slimline contains aspartame, so its ingredients matter as well as its nutrition figures.
People choosing drinks by flavour
Tonic, ginger ale and named cocktail mixers serve different drinks. Choose the style your planned recipe needs, then check whether its pack contains twelve individual portions.
What should you check before buying?
Start with the drink you intend to make, then confirm the pack count and compare the label details that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Confirm 12 individual cans or bottles and the volume of each. Tesco Groceries lists the checked Schweppes tonic cases as 12 × 150ml, or 1.8L in total. | I want twelve separate portions available for planned drinks, rather than relying on an opened larger bottle. |
| Mixer style | Match tonic or ginger ale to the recipe. Check a named cocktail mixer against the cocktail you plan to make; it is not automatically a tonic substitute. | My drinks call for a particular mixer flavour, so the right style matters as much as the case count. |
| Sugar and sweeteners | For the checked Schweppes products, Tesco Groceries lists 7.4g sugars and 32kcal per 150ml of regular tonic, versus 0g sugars and 3kcal for Slimline. Check ingredients too: regular tonic lists sodium saccharin, while Slimline lists aspartame. | If I am choosing between regular and Slimline tonic, I want to compare both the nutrition figures and the sweeteners. |
| Current label | Read the ingredients and nutrition information on the pack, particularly when a sweetener or other ingredient affects your choice. Check the pack format again on the current listing. | For an ingredient-specific choice, I need the details for the product I will actually receive. |
What is easy to overlook?

Thinking Slimline changes only the calories
Tesco Groceries lists 0g sugars and 3kcal per 150ml for Schweppes Slimline Tonic Water, but its ingredients include aspartame. The regular tonic has a different sugar and sweetener profile.
Compare the nutrition table and ingredients list, not just the word “Slimline” on the front.

Choosing tonic for a drink that calls for ginger ale
Tonic and ginger ale bring different flavours to a drink; a case of twelve is not enough reason to treat them as interchangeable.
Settle on the intended drink before selecting the mixer style and pack.
-
Assuming a familiar listing reflects the current pack
Ingredients and retailer listings can change, which matters when you are choosing by sweetener or an exact case count.
Check the current product listing and the label on the pack before using it.
-
Assuming every mixer range comes in twelve portions
Relevant flavours may be sold in other formats. For example, Britvic Limited announced six-can Crafted Lemonade and four-can crafted-soda multipacks for London Essence in May 2025.
If twelve individual mixers are essential, confirm both the unit count and unit volume before choosing a flavour alternative.
Which mixer brands are relevant?
These ranges offer different flavour and pack-format choices; the brand name alone does not establish that a particular mixer comes in a case of 12.

- The listed formats cover tonic and ginger-ale drinks while keeping the requested case count.

Fever-Tree

- The range offers several mixer styles to compare against a planned drink.

Frequently asked questions
Does a case of 12 make twelve finished drinks?
Not necessarily. The Schweppes tonic cases listed by Tesco Groceries contain twelve 150ml portions, totalling 1.8L, but the number of finished drinks depends on how much mixer you use in each one.
Should I choose regular or Slimline tonic?
Choose by the sugar and sweetener profile you want, as well as the drink you are making. Tesco Groceries lists 7.4g sugars and 32kcal per 150ml for Schweppes regular tonic, compared with 0g sugars and 3kcal for Slimline; Slimline contains aspartame.
Can ginger ale replace tonic in a planned drink?
Only if you want the drink to have a ginger-ale flavour instead of a tonic flavour. Tesco Groceries lists Schweppes Canada Dry Ginger Ale in a 12 × 150ml format, but the matching pack size does not make the mixers interchangeable.
What should I read on the mixer label?
Check the current ingredients and nutrition information, particularly if sugar or a sweetener affects your choice. GOV.UK food-labelling guidance also describes phenylalanine wording required when aspartame is named in the ingredients list.
