Choose a 12 x 150ml regular or Slimline Schweppes case when the group wants individual portions of one tonic style; choose the listed 12 x 200ml Fever-Tree mixed case when flavour choice matters more. Check the exact variant, unit size and ingredients before ordering, and bear in mind that the mixed-case seller says unavailable flavours may be substituted.
Who is a case of 12 for?
Gaming-night hosts serving different preferences
Individual portions are straightforward to set out alongside snacks. A case of one tonic keeps the choice simple; a mixed case offers several flavours, provided substitutions would not disrupt your plans.
Groups considering Slimline tonic
If the group wants a no-sugar tonic, check that the case is the Slimline variant rather than relying on the Schweppes brand name. Coca-Cola Great Britain describes Schweppes Slimline Tonic Water as low calorie and no sugar; check the label of the pack you select for its ingredients.
Hosts planning several tonic flavours
The Fever-Tree mixed-case listing describes two of each of six flavours, but its seller allows substitutions. If particular flavours matter for the drinks you plan to serve, check the assortment before ordering.
What should you check before buying?
For a gaming-snack session, settle on one tonic style or a mixed case, then check whether the pack size, contents and labels fit the group.
| Priority | What to check | Your needs |
| Portion size |
Confirm 12 individual units and the volume of each. Tesco lists Schweppes 12 x 150ml cases; the cited Amazon.co.uk Fever-Tree mixed listing is 12 x 200ml. |
I want enough individual portions for the planned drinks without assuming that two 12-packs contain the same total volume. |
| Tonic variant |
Check whether the exact case is regular or Slimline. Compare its nutrition information and ingredients per 100ml; Coca-Cola Great Britain describes Schweppes Slimline Tonic Water as low calorie and no sugar. |
If the group has a sugar or sweetener preference, I need to choose the actual variant that fits it, not just a familiar brand. |
| Flavour choice |
Check how many flavours are included and whether the assortment can change. The cited Fever-Tree seller lists six flavours, two of each, but permits substitutions. |
Several flavours would give guests a choice, but a fixed selection matters more if I have particular drinks planned. |
| Ingredients |
Read the ingredients and allergen information for the exact flavour and pack. The Food Standards Agency says the 14 regulated allergens must be emphasised in the ingredients list of pre-packed food or drink. |
For anyone with an ingredient restriction, I need to check the selected product rather than assume another flavour has the same recipe. |
Multipack mistakes to avoid
-
Comparing cases by unit count alone
Twelve 150ml units and twelve 200ml units provide different amounts of mixer, even though both listings say 12-pack.
Check the volume per unit and the total volume against the drinks you plan to serve.
-
Planning around a fixed mixed-case assortment
The seller of the cited Fever-Tree mixed case says it may replace an unavailable flavour, so the listed selection is not guaranteed.
If a particular flavour is essential, check the current assortment or choose a case with fixed contents.
-
Assuming every tonic has the same ingredients
Regular, Slimline and flavoured tonics are distinct products. Coca-Cola Great Britain describes Schweppes Slimline as no sugar, while Fentimans lists sugar and glucose syrup in its Pink Rhubarb Tonic Water.
Compare the nutrition panel and ingredients of the exact variants you are considering.
Mixer brands and ranges to compare
These ranges illustrate different tonic styles and pack formats; check the individual listing when you need exactly 12 units.
Schweppes
Tesco lists both Tonic Water and Slimline Tonic Water in 12 x 150ml packs.
- The two listings make it possible to compare regular and Slimline cases in the same stated pack size.
- Coca-Cola Great Britain’s low-calorie, no-sugar description applies to Slimline Tonic Water, not every Schweppes mixer.
Fever-Tree
The cited Amazon.co.uk mixed-tonic listing describes a 12 x 200ml selection with two units of each of six flavours.
- One listed case includes several tonic flavours rather than twelve identical units.
- The seller says an unavailable flavour may be replaced, so check the assortment if exact contents matter.
Fentimans
In its April 2021 range announcement, Fentimans listed 200ml tonic flavours alongside soda and ginger-based mixers.
- The announced range included citrus, rhubarb and yuzu tonic variants for shoppers comparing flavours.
- Check the current listing for the required case count; a 200ml product format does not itself establish a 12-pack.
Britvic
Carlsberg Britvic lists Indian, Low Calorie Indian, Elderflower and Raspberry tonic variants.
- The range offers both different flavours and a separately named low-calorie variant.
- Check the particular product listing for its unit count and ingredients before choosing it for a case-of-12 plan.
Tesco own-label
Tesco lists its own-label Low Calorie Indian Tonic Water in a 6 x 250ml format.
- This gives shoppers another stated portion size to compare with the 12 x 150ml cases.
- The cited six-pack is not a case of 12 individual units.

Questions about mixer multipacks
Does every 12-pack contain the same amount of mixer?
No. Tesco lists Schweppes tonic cases at 12 x 150ml, while the cited Amazon.co.uk Fever-Tree mixed case is 12 x 200ml. Check both the number of units and the volume of each when planning drinks for a group.
Should I choose regular or Slimline tonic for gaming night?
Choose according to the tonic style the group wants, then check the exact product label. Coca-Cola Great Britain describes Schweppes Slimline Tonic Water as low calorie and no sugar; that description should not be applied to the regular variant.
Will a mixed tonic case contain exactly the flavours pictured?
Not necessarily for the cited Fever-Tree marketplace case: its seller says unavailable flavours may be replaced. Check the current assortment before ordering if you need a particular flavour.
What should I check for an ingredient restriction?
Read the ingredients and allergen information for the exact flavour and pack you intend to buy. The Food Standards Agency says the 14 regulated allergens must be emphasised in the ingredients list of pre-packed food or drink.
