Who is a case of 12 for?

A case of 12 is most useful when the planned drinks call for individually portioned mixers, rather than one bottle to share.

Hosts planning twelve tonic portions

Schweppes Indian and Slimline Tonic Water are listed in 12 × 150ml formats by Joybuy and Tesco. Count portions rather than guests: anyone wanting a refill will need another portion.

Groups with different drink preferences

Ask whether guests want classic tonic, Slimline tonic or a mixer without tonic’s quinine-led flavour. A single-flavour case keeps serving straightforward, but it cannot provide that variety on its own.

Hosts checking ingredients

If a guest has an ingredient or sweetener requirement, compare the exact products rather than relying on words such as “standard” or “Slimline”. Check the current pack label before serving.

What should you check before buying?

Start with the drinks people plan to make, then check whether twelve portions and one mixer style will cover them.

Priority What to check Your needs
Mixer style Check whether the planned drinks call for quinine-led tonic, a botanical tonic or soda water. Fever-Tree describes its Indian tonic as intended for gin, vodka and fortified wines; Tesco describes its soda water as suitable for mixing or drinking alone. Will my guests want tonic’s bitterness, or do I need a different mixer for some drinks?
Portions A 12 × 150ml case contains twelve 150ml portions, or 1.8 litres altogether. Check the number of tonic drinkers and allow for refills or other drinks. Twelve portions work for my plans only if they cover the serves people are likely to request.
Pack format Check the unit count and volume on the exact listing. Tesco lists soda water as 6 × 250ml, while Sainsbury’s lists its Diet Indian Tonic Water in a 1L bottle; neither is a twelve-unit pack. If twelve separate units matter, a larger bottle or a six-pack will change how I serve drinks.
Ingredients Compare ingredients and nutrition on the same per-100ml basis where needed. Joybuy lists sugar and sodium saccharin for Schweppes Indian Tonic Water; confirm the current label for either tonic. I need to check an exact ingredient or sweetener preference before choosing a case for the group.
Arrival and containers Confirm the delivery option before the event. For the Schweppes Indian Tonic Water case, also confirm whether the delivered containers are cans or bottles if that affects your plans. I need the mixers in time for game night and want to know what I will be opening and serving.

What could catch you out?

  • Counting guests instead of serves

    Twelve 150ml portions will not provide refills for twelve tonic drinkers. Some guests may also want a different mixer or a soft drink.

    Estimate the number of tonic serves, then plan other drinks separately rather than treating one case as the entire evening’s supply.

  • Choosing a flavour before checking the unit count

    A tonic sold in another pack size can suit the planned drinks without meeting an exact twelve-unit requirement. The Fever-Tree Joybuy listing cited here, for example, is 15 × 150ml.

    If twelve individual units are essential, check that count on the specific product. If flavour matters more, decide whether a different pack size still works for your gathering.

  • Assuming “Slimline” answers every preference

    A guest’s flavour preference and ingredient requirements are separate questions. The standard Schweppes Indian Tonic Water listing includes sugar and sodium saccharin; its name alone would not tell you that.

    Ask which tonic people want and check the current ingredient and nutrition panels for the exact cases you are considering.

  • Relying on an earlier product listing

    Ingredients and nutrition information can change, as Tesco and Sainsbury’s caution on their food listings. A previously viewed delivery option may also not suit the event date.

    Check the product and delivery details when ordering, then read the delivered label before serving.

Which brands and retailers are relevant?

These references cover different mixer styles and pack formats; a brand’s presence here does not mean every product in its range comes in a case of 12.

Schweppes

Joybuy and Tesco list Indian and Slimline Tonic Water in 12 × 150ml formats, making these the directly comparable twelve-unit tonic options here.

  • The standard Indian tonic listing names quinine among its flavourings.
  • Both options are tonic; check whether guests want another mixer style as well.

Fever-Tree

Fever-Tree describes its Premium Indian Tonic Water as intended for mixing with gin, vodka and fortified wines.

  • A named tonic to consider when the planned spirit pairing matters more than an exact unit count.
  • The Fever-Tree Joybuy listing cited here is 15 × 150ml, not twelve units; check the pack size of any other variant individually.

Fentimans

Fentimans describes citrus and herbal ingredients in its Premium Indian Tonic Water.

  • The brand’s product information gives 20 kcal and 4.4g sugars per 100ml for this tonic, providing a basis for label comparisons.
  • Check the unit count of the specific listing if twelve separate portions are required.

Tesco

Tesco lists a soda-water alternative for groups that do not all want tonic.

  • Tesco Soda Water is listed as 6 × 250ml for mixing or drinking on its own.
  • That soda-water pack has six units, so it does not meet an exact twelve-unit brief.

Sainsbury’s

Sainsbury’s lists its Diet Indian Tonic Water in a 1L bottle.

  • Its product listing gives 2 kcal and less than 0.5g sugars per 100ml for that specific tonic.
  • One large bottle is not twelve individual portions; Sainsbury’s advises checking the current label because ingredients can change.

Britvic

Britvic describes mixers among its drinks range and announced a cocktail-mixer range in 2023.

  • A range to consider if the planned drinks call for a cocktail mixer rather than tonic.
  • Check the exact product, format and unit count before treating it as a case-of-12 option.

Joybuy cases of 12 to consider

These two Schweppes options are for a game night where twelve individually portioned tonic serves fit the plan. Choose between their stated tonic styles after checking what guests want; arrange other mixers separately if needed.

Schweppes Indian Tonic Water 12 × 150ml

For a group planning classic tonic serves, this case provides twelve 150ml portions.

Schweppes Slimline Tonic Water 12 × 150ml

This twelve-portion case suits a group that specifically asks for Slimline tonic. Each portion is 150ml; confirm the current ingredient and nutrition information for any guest-specific requirements rather than assuming it matches the standard tonic. Check delivery timing before ordering.

Questions about game-night mixers

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

It contains twelve 150ml portions, totalling 1.8 litres. That is twelve single mixer portions, not necessarily enough for twelve guests throughout the evening if people want refills or different drinks.

Should I choose standard or Slimline tonic?

Choose the standard Schweppes Indian Tonic Water case for guests who want its classic quinine-led tonic style; choose the Slimline case when that style is specifically requested. Do not assume their flavours or recipes are identical, and check the current labels for ingredient or nutrition requirements.

Will a Fever-Tree or Fentimans tonic come in twelve units?

Check the exact listing rather than assuming the unit count from the brand. The Fever-Tree Joybuy product cited here is a 15 × 150ml pack, while Fentimans’ product information describes its tonic rather than establishing a twelve-unit pack.

What if a guest has an allergy or ingredient restriction?

Check the ingredient and allergen information on the current pack of the exact mixer before serving it. A description of a brand or another variant is not a substitute for the product-specific label.

Can I use an online nutrition listing to decide what to serve?

Use it to compare prospective products, then check the delivered pack. Tesco and Sainsbury’s both caution that ingredients or nutrition information can change, so the current label matters when a particular detail affects a guest’s choice.
