For a dinner party with varied or undecided drinks, start with individual portions of classic Indian tonic or soda water; choose a light tonic for guests who want that option, or a flavoured tonic when you have a particular pairing in mind. Before buying, check that the pack really contains 12, how much each container holds, and the ingredients on the exact product.
Who is buying the mixers?
Hosts serving different drinks
If guests may choose gin, vodka, aperitifs or alcohol-free drinks, individual portions let them select a mixer without opening every container at once. A classic tonic or soda water gives you a starting point; add a stronger flavour only for drinks you have planned.
Hosts offering a light tonic
If guests have asked for a reduced-calorie tonic, include a named light or slimline option rather than assuming it will suit everyone. Compare its ingredients and nutrition label with the regular tonic you would otherwise serve.
Hosts planning gin pairings
If you have chosen the gin in advance, its flavour can guide the tonic choice. Fever-Tree and Fentimans describe botanical and citrus-led tonics for particular serves; their pairing suggestions are a starting point, not a rule for every guest.
What should you check before choosing?
Decide which drinks you intend to serve, then check the pack and label. A mixer chosen for one pairing may be less useful across a varied drinks table.
Classic tonic or soda water
Choose when: guests may want different spirits or you have not settled the drinks menu.
Bear in mind: Indian tonic has a distinct bitter taste, while soda water contributes less flavour.
Light or slimline tonic
Choose when: you know guests want a reduced-calorie tonic option.
Bear in mind: ingredients and taste can differ from the regular version; check the specific product rather than relying on its name.
Flavoured tonic
Choose when: you have a planned spirit pairing and want the mixer to contribute citrus, floral or botanical notes.
Bear in mind: a pronounced flavour gives guests less flexibility if they choose a different drink.
| Priority | What to check | Your needs |
| Pack format |
Check the container count, millilitres per container and whether the listing describes cans or bottles. Tesco Groceries listed Schweppes tonic in a 12 × 150 ml format; other multipacks need their own count checked. |
I want separate portions for guests, but I need to know whether this pack contains enough mixer for the drinks I plan to make. |
| Flavour |
Match the tonic style to the drinks menu. Fever-Tree describes its Indian tonic as intended for gin, vodka and fortified wines; its Mediterranean tonic has rosemary and lemon thyme notes. |
If guests will choose from several spirits, I would rather keep a straightforward option available than commit every serve to a botanical flavour. |
| Light option |
Read the nutrition and ingredients panels for the exact light tonic and its regular counterpart. Check the sweetener listed instead of assuming the formulations are alike. |
Some guests may ask for light tonic; I do not need to make it the only tonic on the table. |
| Ingredients |
Check the purchased pack, particularly when serving someone with an allergy. GOV.UK guidance says prepacked food and drink must identify any of the 14 regulated allergens present in the ingredients list. |
When a guest needs ingredient information, I want the label for the drink I will actually serve. |
Common buying mistakes
-
Treating every multipack as a case of 12
A pack with fewer containers, or a different volume in each, will not provide the same number or size of individual portions.
Read the full count and volume on the product listing. For example, 12 × 150 ml describes a different format from an eight-pack or a larger sharing bottle.
-
Buying only a strongly flavoured tonic
A citrus or herb-led tonic can suit a planned pairing but may dominate a drink for guests who expected a classic mixer.
If tastes or spirit choices are uncertain, keep classic tonic or soda water available alongside any flavoured option.
-
Assuming light tonic tastes like regular tonic
A light version may have a different ingredient or sweetener formulation, so the two need not taste the same.
Check the exact labels and offer light tonic when guests want it, rather than using the word “light” as a substitute for comparing products.
-
Relying on a general product description for allergies
Ingredient information applies to the particular drink and formulation being served. GOV.UK guidance directs shoppers to the ingredients list for allergens in prepacked food and drink.
Keep the purchased packaging available so an affected guest can check its label before the drink is served.
Brand ranges to consider
These ranges offer different tonic styles and pack formats. Check the individual listing before assuming a particular flavour comes in a case of 12.
Fever-Tree
Its tonic range includes Premium Indian, Refreshingly Light Indian and Mediterranean styles.
- The Mediterranean tonic is described by Fever-Tree as having rosemary and lemon thyme notes, giving hosts a distinct option for a planned serve.
- Do not assume every flavour or container size is sold in a 12-pack; check the specific listing.
Schweppes
Classic and slimline tonic are both relevant to a 12-portion search.
- Tesco Groceries listed Schweppes Tonic Water and Slimline Tonic Water in 12 × 150 ml formats.
- Check the current product listing for the precise format and details of the pack you intend to buy.
Fentimans
The range covers classic, light and more flavour-led tonics, including yuzu.
- Fentimans suggests its Oriental Yuzu Tonic for strong London Dry or botanically rich gins, offering a pairing to consider if that is your planned serve.
- A flavour-led choice may not suit every drink on the table; confirm the pack count separately.
Britvic
Britvic's mixer range includes Indian tonic in a retail multipack can format.
- Britvic announced a six-pack of 330 ml Indian Tonic cans in 2023, an example of a format for separate serves.
- That six-pack is not a case of 12; check the current pack description if 12 portions are required.
Tesco
Its tonic and mixers category brings own-label drinks and branded multipacks into the same shopping range.
- A category listing can help identify whether you want tonic, soda water or a flavoured mixer before comparing individual packs.
- Use the product-detail listing to confirm count, volume and ingredients for the option you choose.
Joybuy tonic multipacks
These tonic options include two 12 × 150 ml packs and alternatives with eight or 15 portions. If you need exactly 12, check the count in each title before choosing by flavour.

Fever-Tree Refreshingly Light Premium Indian Tonic Water 15 × 150 ml

Fever-Tree Refreshingly Light Mediterranean Tonic Water 8 × 150 ml
A Mediterranean-style tonic for a planned flavour pairing rather than an assumed choice for every guest. The 8 × 150 ml pack has fewer portions than a case of 12.

Fever-Tree Indian Tonic Water 8 × 150 ml
A classic Indian tonic option if eight individual portions meet your plans. The 8 × 150 ml pack does not meet an exact case-of-12 requirement.

Questions about dinner-party mixers
Is a case of 12 enough for a dinner party?
Check the volume per container and how many mixed drinks you expect to make; the count alone cannot answer that question. Tesco Groceries listed 12 × 150 ml tonic packs, but a different container size changes the total volume, and other soft drinks may also be on the table.
Should I buy regular or light tonic?
Choose a light tonic when guests have asked for that option; regular and light versions need not have the same ingredients or taste. Check the labels of the particular products you are considering instead of assuming that one will replace the other for every guest.
What mixer should I choose if guests' drinks are undecided?
Start with classic Indian tonic or soda water, and add a flavoured tonic if you have a specific pairing planned. Fever-Tree describes its Indian tonic for gin, vodka and fortified wines, while its Mediterranean tonic has more distinctive rosemary and lemon thyme notes.
Where should I check allergen information?
Check the ingredients list on the exact prepacked drink you will serve. GOV.UK guidance says that any of the 14 regulated allergens present must be clearly identified there; keep the pack available for guests who need to read it.
