Hosts serving drinkers and non-drinkers
Keep soft drinks and alcoholic bases clearly identified. A mixer can be served on its own or paired with a base labelled 0.0%; check the base before describing a mixed drink as alcohol-free.
Who are the drinks for?
A BBQ drinks table may need separate serves for guests avoiding alcohol, guests reducing alcohol units and guests choosing a mixer by its ingredients.
Guests reducing alcohol units
Choose the strength and measured volume of the alcoholic base before choosing a mixer. The NHS calculates units from ABV and volume, so swapping regular tonic for slimline tonic does not change the units in an unchanged spirit pour.
Tonic drinkers checking ingredients
No-sugar and reduced-calorie tonics are different choices. Tesco lists Schweppes Slimline Tonic Water at 0g sugars and 5kcal per 250ml; Fever-Tree Refreshingly Light Indian Tonic lists 3.8g sugars and 15kcal per 100ml. Compare the exact packs, including their sweeteners.
What should you check before buying?
A drink without an alcoholic base
Choose it when: A guest wants a soft drink on its own or a mixed serve made with a base labelled 0.0%.
Keep in mind: The mixer does not establish the ABV of a separately added base; check that product’s label and keep serving ingredients distinct.
An alcoholic drink with fewer units
Choose it when: A guest still wants an alcoholic mixed drink but wants to control the amount of alcohol in the serve.
Keep in mind: A light mixer changes neither the strength nor the volume of an unchanged alcoholic pour.
| Priority | What to check | Your needs |
|---|---|---|
| Alcohol-free serves | Check the ABV on any alcohol-free substitute used as a base. Identify soft drinks and added bases separately when serving. | I want guests avoiding alcohol to know what is in their glass, rather than having to judge by the mixer’s name. |
| Alcohol units | Check the alcoholic base’s ABV and measure the amount poured. The NHS calculates units as ABV × volume in ml ÷ 1,000. | For an alcoholic mixed drink, I want to control the amount of alcohol poured; changing only the tonic will not do that. |
| Sugar and ingredients | Compare sugars and energy using the same serving size, then read the ingredients. Tesco lists 0g sugars and 5kcal per 250ml for Schweppes Slimline; Fever-Tree Refreshingly Light lists 3.8g sugars and 15kcal per 100ml. | A no-sugar tonic and a reduced-calorie tonic do not meet the same ingredient preference. I would check the pack before serving either to someone who avoids a particular sweetener. |
| Flavour and serving format | Decide whether guests want bitter tonic, ginger ale or lemonade. Check whether the chosen drink is for serving on its own, mixing, or both. | Some guests would rather have a sparkling soft drink than tonic, so I want a clearly identified non-tonic option on the table. |
Mistakes to avoid
-
Reading “light” or “slimline” as an alcohol claim
Those words describe the mixer, not the alcohol in a completed drink. Under the NHS units calculation, the same strength and volume of spirit contribute the same units whichever tonic is added.
Choose and measure the alcoholic base first; then pick the mixer for flavour and its stated nutrition and ingredients.
-
Providing one mixer for every guest
A bitter tonic will not cover every flavour preference, and its presence does not give guests an alcohol-free mixed drink if only alcoholic bases are offered.
Set out a clearly identified soft drink alongside tonic and a non-tonic flavour such as ginger ale or lemonade. Label any bases separately.
-
Assuming reduced-calorie means no sugar
Fever-Tree Refreshingly Light Indian Tonic lists sugars, while Tesco’s Schweppes Slimline listing gives 0g sugars and includes aspartame. Those details matter when a guest has a particular ingredient preference.
Read both the nutrition and ingredients panels on the exact pack rather than relying on the front-of-pack name.
Brand ranges to consider
These ranges offer different tonic and flavour choices; the details of a particular drink still depend on its own label.
Fever-Tree
Refreshingly Light Indian Tonic is a bitter tonic option for guests considering the brand’s reduced-calorie formulation.
- Fever-Tree describes Refreshingly Light as having fewer calories than its regular Premium Indian Tonic.
- It lists 3.8g sugars per 100ml, so reduced-calorie does not mean sugar-free. Mixing it with an unchanged spirit pour does not reduce alcohol units.
Schweppes
Slimline Tonic Water is a classic tonic option for guests looking for a no-sugar mixer.
- Tesco lists 0g sugars and 5kcal per 250ml for Schweppes Slimline Tonic Water.
- The Tesco ingredients list includes aspartame. The tonic does not alter the units in an unchanged alcoholic pour.
Fentimans
Fentimans lists tonic, ginger ale, ginger beer and rose lemonade for hosts who want flavour choices beyond classic tonic.
- The range includes both bitter tonic and non-tonic soft-drink flavours.
- Check the nutrition, ingredients and intended serving of the exact mixer, as well as the ABV of any base added to it.
Joybuy options for the drinks table
These options include tonics, ginger ale and a sparkling soft drink for a BBQ. Choose any alcoholic or 0.0% base separately, and check its label before preparing a mixed serve.

Schweppes Slimline Tonic Water, 12 × 150ml
A tonic option for guests who prefer a no-sugar mixer. The pack contains 12 × 150ml cans; check its ingredients for sweeteners. An unchanged alcoholic pour contributes the same units whichever tonic is added.
No image available
Fever-Tree Refreshingly Light Premium Indian Tonic, 15 × 150ml
An Indian tonic to serve on its own or with a separately chosen base. The pack contains 15 × 150ml cans. This formulation contains sugar, so check the nutrition panel if a no-sugar mixer is the priority.
No image available
Fever-Tree Refreshingly Light Ginger Ale, 8 × 150ml
A ginger ale for a non-tonic choice, served on its own or used as a mixer. The pack contains 8 × 150ml cans. Check the label for sugars and ingredients if those affect your choice; any added alcoholic base determines the alcohol in a mixed serve.
No image available
Double Dutch Skinny Tonic, 24 × 200ml
A tonic option for guests considering a different flavour from classic Indian tonic. The pack contains 24 × 200ml servings. Check the energy and sugar figures on the pack before comparing it with another tonic; “skinny” alone does not establish either figure.
No image available
7 Up Lemonade Zero, 24 × 330ml
A sparkling soft drink to serve on its own for guests who do not want tonic. The pack contains 24 × 330ml cans. Check the ingredients if sweeteners matter to your guests; do not assume that adding another drink will leave the serve alcohol-free.
Questions about BBQ mixers
Does a slimline tonic make an alcoholic drink lower in alcohol?
No, not if the alcoholic base and the amount poured stay the same. The NHS calculates alcohol units from ABV and volume in ml, divided by 1,000; changing the mixer alone does not change those inputs.
How can I offer a drink without an alcoholic base?
Serve a soft drink on its own, or pair a mixer with a base labelled 0.0% after checking that base’s ABV. Keep the ingredients for alcoholic and non-alcoholic serves clearly identified so guests can choose.
Is a reduced-calorie tonic necessarily sugar-free?
No. Fever-Tree Refreshingly Light Indian Tonic lists 3.8g sugars per 100ml, while Tesco lists 0g sugars per 250ml for Schweppes Slimline Tonic Water. Compare the exact packs’ nutrition and ingredients panels, including any sweeteners.
Can the mixer name tell me whether a mixed drink contains alcohol?
No. Check the ABV of every base added to the mixer and the amount used. A light or slimline mixer does not establish the alcohol content of the completed drink.
