Couples planning dinner for two
Count the drinks you expect to serve before choosing between eight and twelve 150ml portions. Unopened portions can be kept for another occasion, while a partly used large bottle may lose its fizz.
Who is choosing the mixers?
Hosts serving classic gin or vodka drinks
A classic tonic provides a familiar option when guests may choose different spirits. Individual 150ml portions also make it easier to open mixer only as it is needed.
Hosts choosing a particular flavour pairing
If the spirit is already chosen, consider whether a floral or botanical tonic fits the intended drink. Fever-Tree and Fentimans describe pairings for specific products; those descriptions are brand guidance, not independent taste assessments.
What matters when choosing?
Start with the number of drinks, then choose the container and flavour for the way you plan to serve them.
| Priority | What to check | Your needs |
|---|---|---|
| Portion count | An 8 × 150ml pack contains 1.2 litres; a 12 × 150ml pack contains 1.8 litres. Count expected mixer serves, including any drinks without spirits. | For dinner for two, I would rather match the pack to the drinks planned than open more mixer than we will use. |
| Container | Check whether the exact pack contains individual portions or a larger bottle. Tesco Groceries lists own-label Indian tonic in a 1-litre format. | Individual portions suit a few drinks served at different times; a bottle suits us if several drinks will be poured soon after opening. |
| Flavour | Check the exact tonic variant against the chosen spirit. Fever-Tree positions its light elderflower tonic for fresh or floral gins and vodka; Fentimans describes its Connoisseurs Tonic as a botanical option. | If the spirit is already decided, I can choose a matching flavour. For mixed preferences, I would start with a classic tonic. |
| Guest requirements | Read the ingredients, allergen information and nutrition label on the exact pack. Plan a drink without added alcohol if a guest wants one. | I want each guest to be able to check what is in their drink, with the mixer kept separate from any spirit. |
What is easy to overlook?
-
Choosing a flavoured tonic before the spirit
A floral or botanical tonic changes the flavour of the finished drink, so the pairing matters more than the flavour name alone.
Decide which spirits you will serve first. If guests have different preferences, keep a classic tonic available alongside any flavoured option.

Assuming one mixer suits every guest
Ingredients can differ between tonic variants, and a soft-drink mixer does not tell you whether a guest wants an alcoholic serve.
Check the exact pack’s ingredients and allergen information, and offer a drink without added alcohol.

Questions about serving mixers
How many mixer portions do two people need?
Count the drinks you expect to make. An 8 × 150ml pack contains eight portions and a 12 × 150ml pack contains twelve, so either leaves spare portions if each person has just one drink using 150ml of mixer.
When does a 1-litre bottle make sense instead of individual portions?
Consider a 1-litre bottle when several drinks will be poured soon after opening and you want to vary the amount in each. Individual portions are easier to keep unopened when drinks are served at different times.
Do all Fever-Tree light tonics have the same formulation?
No. Light elderflower, Naturally Light Indian and Refreshingly Light Mediterranean are distinct variants. Read the ingredients and nutrition information on the exact pack rather than applying one variant’s details to another.
What if a guest has an allergy or dietary restriction?
Check the label of the exact mixer you will serve, including its ingredients and allergen information. Do not rely on the label of a different flavour or an older product listing.
Can tonic be served without a spirit?
Yes. The tonic products discussed here are soft-drink mixers and can be served without adding alcohol. Keep any spirit separate so guests can choose the drink they want.
