Couples making two drinks
If you plan one drink each, a 150ml can can supply each mixer portion without opening a large bottle. A 200ml bottle gives you more mixer per drink if that suits your recipe.
Who is choosing a mini mixer?
Hosts offering guests a choice
Separate cans or bottles let guests choose different mixers. Fever-Tree and Schweppes have 150ml tonic multipacks listed by UK retailers; Fentimans also offers a 200ml tonic format.
Hosts checking ingredients
Compare the exact tonic variants rather than relying on names such as light or slimline. Their nutrition figures and sweetener ingredients can differ.
What should you check before buying?
Start with the drinks you intend to make, then choose a portion size and recipe for each guest.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check the mixer quantity in your recipe and the size of each container. Sainsbury’s lists Fever-Tree’s suggested serve as 50ml spirit with 150ml mixer; Fentimans lists a 200ml Naturally Light Tonic Water bottle. | For two smaller mixed drinks, I would rather open individual portions. If we plan longer drinks, I need more than 150ml of mixer per serve. |
| Flavour | Check whether the mixer is tonic, ginger ale or another flavour, and read the stated ingredients. Fentimans Naturally Light Tonic Water, for example, lists juniper berry and kaffir lime leaves. | I want the mixer to suit the spirit and each guest’s taste, rather than choosing every drink from the same opened bottle. |
| Nutrition | Compare energy and sugars per 100ml on the exact variant. Sainsbury’s lists Fever-Tree Premium Indian Tonic Water at 36kcal and 8g sugars per 100ml, and its Refreshingly Light Premium Indian variant at 15kcal and 3.8g. | If a guest wants to compare recipes, I can check the figures on the products I am considering without assuming every light tonic is alike. |
| Ingredients | Read the physical pack for quinine, sweeteners and allergen information. Sainsbury’s lists fructose in Fever-Tree Refreshingly Light Premium Indian Tonic Water; its Diet Indian Tonic Water lists acesulfame K and sucralose. | Before serving someone with a dietary requirement, I want to confirm the ingredients of their particular mixer. |
Choices that can catch you out
-
Opening a large bottle for two different drinks
A large bottle does not give you separate flavour choices, and any remainder needs handling according to its label. Sainsbury’s Diet Indian Tonic Water, for example, says to refrigerate it after opening and use it within three days.
If each guest wants a different mixer, choose individual cans or bottles in the sizes your recipes require. Use a larger bottle when you expect to serve enough of that same mixer.
-
Treating light and diet tonics as the same recipe
Ingredients differ between products: Sainsbury’s lists fructose in Fever-Tree Refreshingly Light Premium Indian Tonic Water, while its Diet Indian Tonic Water lists acesulfame K and sucralose.
Compare the per-100ml nutrition panel and ingredient list for the exact variant, particularly when a guest avoids an ingredient.
-
Choosing a flavoured mixer without checking the drink
A botanical tonic changes the flavours you put into the glass. Fentimans Naturally Light Tonic Water lists juniper berry and kaffir lime leaves, which may not be what a guest expects from a plain tonic.
Ask which flavours your guests want and check the mixer’s description against the spirit you plan to serve.
-
Relying on a product page instead of the pack
The pack in hand is the one your guests will drink; its size and ingredient list are the details that matter at serving time.
Check the exact variant, ingredients, any allergen information and best-before date on the physical pack.
Brand and format references
These examples help distinguish portion sizes and recipes; a brand’s wider range need not use the same format or ingredients.
Fever-Tree
Sainsbury’s lists Premium Indian and Refreshingly Light Premium Indian Tonic Water in 8 × 150ml cans.
- The 150ml can matches Fever-Tree’s stated 50ml spirit and 150ml mixer serve.
- The two variants have different per-100ml nutrition figures; check which recipe you are buying.
Schweppes
Tesco lists both Tonic Water and Slimline Tonic Water in 12 × 150ml multipacks.
- Individual 150ml cans allow separately portioned drinks.
- The standard tonic’s Sainsbury’s listing includes sugar and sodium saccharin; do not assume its ingredients match the Slimline variant.
Fentimans
Fentimans lists Naturally Light Tonic Water in 200ml bottles, individually and in packs of four.
- A 200ml bottle gives more mixer per container than a 150ml can and suits a drink planned around that quantity.
- Its listed juniper berry and kaffir lime leaves make the exact flavour worth checking before pairing it with a spirit.
Britvic
Britvic described a move to 200ml mixer bottles in its 2016 range announcement, intended for single and double measures.
- The documented bottle size offers another portion to consider when planning a larger drink.
- Check the particular product and seller before making plans around that historical range announcement.
Tesco
Tesco lists its own-label Low Calorie Indian Tonic Water in 6 × 250ml cans.
- A 250ml can gives more mixer for a deliberately longer drink.
- It is not the same portion as a 150ml can; check how much your recipe calls for.
Sainsbury’s
Sainsbury’s lists own-label Indian Tonic Water and Diet Indian Tonic Water in 1L bottles.
- A larger bottle can serve several drinks when guests want the same mixer.
- The 1L format is not a mini portion. Its Diet Indian Tonic Water label says to refrigerate after opening and use within three days.

Questions about mini mixers
Is one 150ml can enough for a drink?
It matches Fever-Tree’s suggested serve of 50ml spirit with 150ml mixer, as listed by Sainsbury’s. For a deliberately longer drink, choose a larger mixer portion or have another container available.
Should I choose standard, light or diet tonic?
Choose the recipe that suits the intended drink and your guests’ preferences, then compare the exact labels. Sainsbury’s lists 36kcal per 100ml for Fever-Tree Premium Indian Tonic Water, 15kcal for its Refreshingly Light Premium Indian variant and 2kcal for Sainsbury’s Diet Indian Tonic Water; they also differ in ingredients and container size.
Does tonic water contain quinine?
Check the particular product: Sainsbury’s lists quinine in Schweppes Tonic Water and in the ingredients of Fever-Tree Refreshingly Light Premium Indian Tonic Water. Do not assume every mixer has the same recipe.
What should I check before serving a guest with dietary requirements?
Read the exact pack’s ingredient list, allergen information and nutrition panel before serving. Check the particular variant rather than relying on another flavour or an earlier online description.
What should I do with mixer left in an opened bottle?
Follow that bottle’s storage instructions. Sainsbury’s Diet Indian Tonic Water says to refrigerate after opening and use within three days; that instruction should not be applied to every mixer.
