Who might choose these mixers?

Shoppers planning one small mixer per serve

A 12 × 150ml case gives you twelve individual portions for dinner rather than one large bottle. Tesco lists a total of 1,800ml for both Schweppes cases.

People comparing sugar and sweeteners

Tesco lists 0g sugars per 150ml serving for Schweppes Slimline. Its ingredients include aspartame, and the Joybuy product page warns that it contains a source of phenylalanine.

Hosts choosing a mixer for a particular drink

If the tonic’s botanical or citrus ingredients matter to your planned serve, compare recipes as well as pack sizes. Fever-Tree and Fentimans describe flavour-led tonics, but their pairing suggestions are the brands’ own guidance.

What should you check before buying?

Start with the number and size of the portions, then compare recipes and labels against the drinks and guests you have in mind.

Priority What to check Your needs
Pack format Check the container count and volume separately. Tesco lists each Schweppes case as 12 × 150ml, totalling 1,800ml. I want individual portions for dinner, not a large sharing bottle or a multipack with fewer than twelve containers.
Recipe Tesco lists 7.4g sugars per 150ml for regular Schweppes tonic and 0g for Slimline. Check the ingredient list too: regular contains sugar and sodium saccharin; Slimline contains aspartame. If I prefer the regular sugar-containing recipe, I can choose accordingly. If I want no sugar in the tonic, I need to check whether Slimline’s sweetener suits everyone being served.
Flavour Compare the named flavourings and whether a mixed case allows substitutions. Fever-Tree describes bitter-orange oils in its Premium Indian Tonic; Fentimans lists botanical extracts in Connoisseurs Tonic. A particular drink calls for a particular tonic flavour, so I would check the exact variety rather than assume every case contains the same recipe.
Guest requirements Read the current ingredients, nutrition and dietary declarations for the exact product. The Joybuy Slimline page warns that its aspartame provides a source of phenylalanine. Before serving guests, I need to check the label on the pack delivered, especially where an ingredient matters to someone at the table.

What could catch you out?

  • Assuming every mixer multipack contains twelve portions

    Mixer listings include different container counts and sizes. A suitable flavour will not meet a twelve-portion plan if the pack contains fewer containers.

    Check both figures on the listing: the two Schweppes cases described by Tesco contain 12 × 150ml, or 1,800ml in total.

  • Treating Slimline as regular tonic with only the calories changed

    The recipes differ. Tesco lists sugar and sodium saccharin in regular Schweppes tonic, while Slimline contains aspartame; the Joybuy Slimline page also gives a phenylalanine warning.

    Compare the full ingredient and nutrition declarations, then check the delivered pack before serving it.

  • Assuming a mixed case guarantees particular flavours

    The Amazon UK listing for a Fever-Tree 12 × 200ml mixed pack says unavailable tonic flavours may be replaced. That matters if you have planned drinks around a specific variety.

    Choose a specified single-flavour pack or confirm the mixed case’s contents with the seller before ordering.

Which brands are relevant?

Schweppes

Tesco and Joybuy list regular and Slimline Schweppes tonic in 12 × 150ml formats, making them direct options for twelve small serves.

  • Both listed formats contain twelve 150ml portions.
  • The recipes differ: regular contains sugar and sodium saccharin; Slimline contains aspartame and carries a phenylalanine warning.

Fever-Tree

Fever-Tree describes its Premium Indian Tonic as containing quinine and Mexican bitter-orange oils, and suggests pairing it with gin, vodka or fortified wines.

  • The brand’s ingredient description helps when selecting a particular tonic variety.
  • The Amazon UK listing for a 12 × 200ml mixed Fever-Tree pack permits flavour substitutions; check its contents if the assortment matters.

Fentimans

Fentimans lists quinine and fermented botanical extracts, including juniper berry and lemongrass, in its Connoisseurs Tonic.

  • The published ingredient list gives you a way to compare this recipe with other tonics.
  • Check the container count and size of any Fentimans pack against a twelve-portion dinner plan.

Britvic

Britvic describes mixers among its drinks range. For a case-of-12 purchase, the specific variety and pack format matter more than the brand name alone.

  • Britvic’s range gives shoppers another brand to consider when comparing mixer varieties.
  • Confirm the current listing’s container count and volume before relying on it for twelve serves.

Common questions

How much tonic is in a 12 × 150ml case?

It contains 1,800ml in twelve individual portions, as Tesco lists for both Schweppes cases. How many drinks that covers depends on the amount of mixer you pour into each one.

What is the difference between regular and Slimline Schweppes tonic?

Both Tesco-listed cases contain 12 × 150ml, but their recipes differ. Tesco lists 7.4g sugars and 32kcal per 150ml for regular tonic, compared with 0g sugars and 3kcal per 150ml for Slimline; Slimline contains aspartame, and Joybuy warns that it provides a source of phenylalanine.

Should I check the pack if I have read the online ingredients?

Yes. Use the listing to compare products, then check the delivered pack’s current ingredients, nutrition and dietary declarations before serving it, particularly when a guest needs to avoid an ingredient.

Will a mixed tonic case contain every advertised flavour?

Not necessarily. The Amazon UK listing for a Fever-Tree 12 × 200ml mixed pack says unavailable flavours may be replaced. If a specific variety is needed for dinner, confirm the case’s contents with the seller before ordering.
