Shoppers stocking individual mixer serves
A 12 x 150ml case provides twelve portions and 1.8 litres in total. Check both the portion size and total volume when considering a different pack format.
Who is a case of 12 for?
Gin-and-tonic buyers choosing a formulation
Decide whether the intended drinks call for classic, slimline or lemon-flavoured slimline tonic before committing to twelve of the same variant.
Shoppers with ingredient or allergen requirements
Check the ingredients and allergen information for the exact variant before buying a full case, particularly when someone drinking it has an allergy or intolerance.
What should you check before buying?
Choose the mixer style first, then check whether the pack gives you the portions and label information you need.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check the count and volume of each portion. Twelve 150ml portions total 1.8 litres; compare total volume when pack sizes differ. | I want individual serves, but I also need to know how much mixer the whole pack contains. |
| Mixer style | Choose between classic, slimline and lemon-flavoured slimline tonic. If you want ginger ale, check that you are selecting it instead of tonic. | Will the same flavour and formulation work for everyone using the case? |
| Product label | Read the current ingredients, allergen information and nutrition values per 100ml for the exact variant. A name such as “slimline” is not a complete ingredient description. | I need to check the actual formulation rather than assume that similar-looking mixers have the same ingredients. |
Common case-buying mistakes
-
Comparing pack counts without checking volume
Twelve 150ml portions contain 1.8 litres; a pack with a different count or portion size may contain a different total amount.
Check the volume per portion and the total volume, as well as whether the pack suits how you plan to serve it.
-
Choosing lemon tonic for a group that wants plain tonic
A lemon-flavoured case commits every portion to that flavour, which gives less choice to people who prefer an unflavoured mixer.
Choose the flavoured case when lemon suits the intended drinks; otherwise, consider plain tonic.
-
Relying on “slimline” as a complete label description
The word does not tell you every ingredient or nutrition value for the exact product.
Read the current ingredients, allergen information and nutrition panel before deciding whether the variant meets your requirements.
Mixer brands and formats to know
Schweppes
Tesco Groceries lists classic, slimline and lemon-flavoured slimline Schweppes tonic in 12 x 150ml packs.
- The three listed variants offer a choice of tonic style in the same 1.8-litre case format.
- Check the current label for the ingredients and nutrition of the variant you choose.
Fever-Tree
Fever-Tree describes a tonic range that includes Indian, Mediterranean, aromatic and flavoured varieties.
- The range gives shoppers specific tonic flavours to consider for their intended drinks.
- Check the count and portion size of a particular pack if you need exactly twelve serves.
Fentimans
Fentimans describes its Premium Indian Tonic Water as containing herbal infusions, Sicilian lemon oil and lemongrass extract. It also lists soda water in a 200ml format.
- Consider the tonic for its stated botanical ingredients, or soda water when that is the mixer you want.
- Check the retail pack format rather than assuming either product comes as a case of twelve.
Britvic
Britvic’s 2016 range announcement described tonic, ginger ale, soda, bitter lemon and lemonade variants.
- Those named variants cover several mixer styles.
- The 2016 announcement describes formats including 200ml and 125ml bottles and 150ml cans; check the format of any pack you are considering now.
Tesco
Tesco Groceries is the retailer listing the three Schweppes 12 x 150ml tonic variants described above.
- Its listings distinguish classic, slimline and lemon-flavoured slimline cases.
- A listing for Schweppes is not a Tesco own-label mixer; check the brand and variant on the pack.

Questions about 12-pack mixers
Does every case of 12 contain the same amount of mixer?
No. A 12 x 150ml case contains 1.8 litres, but the total changes if each portion is a different size. Check both the count and the volume per portion when comparing packs.
Should I choose classic or slimline tonic?
Choose the formulation that suits the intended drinks and the people using the case. If ingredients or nutrition matter to your choice, read the current label of the exact classic or slimline variant rather than relying on its name alone.
What allergen information should I check on a mixer?
Read the ingredient and allergen information for the exact variant you intend to buy. GOV.UK guidance states that UK food businesses must provide allergen information when listed allergens are ingredients; checking the current pack is particularly important for someone with an allergy.
Can a different tonic pack replace a 12 x 150ml case?
Yes, if its flavour, portion size and total volume still suit how you plan to use it. A different pack count is not the same serving format, so check those details before substituting it for twelve individual portions.
