Hosts serving gin and mixed drinks
If gin-led drinks are planned, a classic tonic gives guests a familiar option. Soda water provides a different, unsweetened base for drinks where tonic flavour is not wanted.
Who are the drinks for?
Hosts offering alcohol-free or lower-sugar choices
Guests may want a sparkling drink on its own or a mixer with less sugar. Coca-Cola Great Britain lists Schweppes Soda Water at 0 g sugars per 100 ml, while Fentimans lists 3.4 g sugars per 100 ml for its Naturally Light Tonic Water; the two serve different flavour preferences.
Hosts planning a flavour-led drinks table
A ginger option gives guests a distinct choice alongside tonic. Fentimans describes its ginger beer as spicy and ginger-forward, so keep it separate rather than treating it as a replacement for every gin and tonic.
What should you check before buying?
Start with the drinks you intend to make, then choose a contrasting flavour and check the exact packs for serving size and ingredients.
| Priority | What to check | Your needs |
|---|---|---|
| Main mixer | Match tonic to planned gin-led serves. For a sparkling option without tonic flavour, check a soda water’s ingredients and nutrition panel. | I want a base that suits the drinks on the menu, rather than several mixers that do the same job. |
| Flavour variety | Compare a flavoured tonic’s stated flavour with the spirit you plan to serve. Treat ginger beer as a separate ginger-led option, not another standard tonic. | Guests should be able to spot a different flavour without having to choose between near-identical tonics. |
| Sugar and sweeteners | Compare sugars and energy per 100 ml on the exact pack, and read the ingredients for sweeteners. Fentimans lists 3.4 g sugars per 100 ml for Naturally Light Tonic Water, so its name does not mean sugar-free. | I’d like guests to have a clear choice between sweetened, lighter and no-sugar drinks where those options suit the menu. |
| Dietary details | Check each current pack’s ingredients and allergen information. Do not apply a statement about one product to an entire brand range. | If a guest has an allergy, intolerance or other dietary requirement, I need the information for the drink actually being served. |
Common buying mistakes
-
Treating every sparkling mixer as interchangeable
Tonic, soda water and ginger beer have different flavour profiles. Fentimans describes its ginger beer as spicy, while Coca-Cola Great Britain lists Schweppes Soda Water without sugar.
Choose tonic for planned gin-and-tonic serves, soda where an unsweetened option fits, and ginger beer for drinks intended to have a pronounced ginger flavour.
-
Assuming a light tonic contains no sugar
Fentimans lists 3.4 g sugars per 100 ml for Naturally Light Tonic Water.
Read the exact nutrition panel if sugar content matters, and choose a product explicitly labelled no sugar when that is the requirement.
-
Making brand-wide dietary assumptions
Ingredients and product-specific dietary statements can differ across mixers from the same brand.
Check the current pack for each drink and keep the ingredient information available when serving guests with relevant dietary requirements.
Brand ranges to consider
Fever-Tree
Fever-Tree lists Indian, Mediterranean and several flavoured tonic waters, including elderflower and aromatic varieties.
- The range offers an aromatic option alongside a standard tonic.
- Fever-Tree’s suggested gin pairings are the brand’s own positioning; choose a flavour for the spirits and guests you have in mind.
Schweppes
The Schweppes range includes tonic, slimline tonic and soda water. A separate UK listing describes classic tonic in 24 individual 200 ml bottles.
- Coca-Cola Great Britain lists Schweppes Soda Water at 0 g sugars per 100 ml and describes Slimline Tonic as containing no sugar.
- Ingredients and sweeteners differ between products, so check the formulation on the pack you buy.
Fentimans
Fentimans offers Premium Indian Tonic Water, Naturally Light Tonic Water and ginger beer as distinct mixer choices.
- Its product descriptions distinguish the citrus-and-herbal tonic from the pronounced ginger flavour of its ginger beer.
- Naturally Light Tonic Water still contains sugar, and ginger beer will not suit every drink intended for plain tonic.
Britvic
Britvic’s Great Britain portfolio lists 7UP and 7UP Zero Sugar as lemon-and-lime sparkling soft drinks.
- They provide a lemon-and-lime soft-drink choice for guests who want something sparkling without a spirit.
- A lemon-and-lime soft drink is not a like-for-like substitute for tonic, soda water or ginger beer in a planned mixed drink.

Frequently asked questions
Should I buy only tonic water for a birthday party?
Buy only tonic if the planned drinks and guests call for it. If you also need an unsweetened sparkling option or a more pronounced flavour, consider soda water or ginger beer alongside a classic tonic rather than buying several similar tonics.
Does a lighter tonic contain no sugar?
Not necessarily. Fentimans lists 3.4 g sugars and 18 kcal per 100 ml for Naturally Light Tonic Water, so check the exact nutrition panel if you need a no-sugar choice.
What should I check for a guest with an allergy or dietary requirement?
Read the ingredients and allergen information on the exact current pack before serving it. A dietary statement about one mixer does not establish that every product in the brand’s range has the same ingredients.
Can ginger beer be served as a mixer and on its own?
Yes, where the product’s serving information allows both uses. Fentimans describes its ginger beer as a mixer with a pronounced spicy flavour; present ginger beer as a distinct choice rather than assuming it will work in every drink planned with tonic.
