Occasional one-drink households
If you usually make one gin and tonic, spirit mixer or alcohol-free long drink, a 150ml portion lets you open one mixer at a time. Fever-Tree’s suggested spirit-and-mixer serve uses that amount.
Who might prefer smaller mixer packs?
Smaller portions are worth considering when the amount you pour for one or two drinks matters more than the total volume in the cupboard.
Couples making drinks at home
For one or two drinks, compare the amount you normally pour with the pack’s individual serving size. A 200ml bottle gives you a different portion from a 150ml can; the better fit depends on your glasses and usual mixer-to-spirit ratio.
Shoppers choosing between tonic styles
A small serving does not settle whether to buy standard, light or slimline tonic. Compare the flavour description, ingredients and nutrition panel on the particular product.
What should you check before choosing?
Start with the amount of mixer you use in one occasion, then choose the flavour and formulation you would want in that portion.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Compare 150ml cans, 200ml bottles and larger bottles with the amount you actually pour. Fever-Tree’s suggested serve uses 150ml of mixer with 50ml of spirit. | I usually make one drink, so a 150ml portion may fit. If I pour more mixer, a 200ml bottle is worth considering. |
| Number of drinks | Check the number of individual portions in a multipack and whether a larger opened bottle would be used during the same occasion. | We sometimes make two drinks together, but I would choose a larger bottle only if we expect to use its contents. |
| Flavour | Compare a classic Indian tonic’s quinine-led bitterness with the citrus and herbal notes described for Fentimans Premium Indian Tonic Water. Check the named variant rather than assuming all tonics taste alike. | I want the mixer’s flavour to suit the drink I am making, whether that is a straightforward bitter tonic or a more noticeable botanical profile. |
| Ingredients | Read the current ingredients, sweetener wording and nutrition panel for the exact standard, light or slimline product. Do not treat those names as interchangeable recipes. | If a particular ingredient or the product’s sugar content matters to me, I want to check the pack itself before choosing. |
| Spirit measure | Measure any spirit separately and check its alcohol by volume (ABV). Mixer portion size alone does not tell you the alcohol content of a finished drink. | A small tonic can helps me portion the mixer, but it does not determine how much alcohol I have poured. |
Mixer-buying mistakes to avoid
-
Choosing a large bottle for an occasional single drink
A bottle containing several mixer portions may remain partly used if you normally make only one drink at a time.
Work out how much mixer you typically pour in an occasion before choosing between individual portions and a shared bottle.
-
Assuming every tonic has the same flavour
Schweppes describes a bitter quinine finish for its Indian Tonic Water, while Fentimans describes citrus and herbal notes for its Premium Indian Tonic Water. The mixer can therefore make a noticeable difference to the drink you prepare.
Choose the named tonic style for the flavour you want, particularly if you are pairing it with a specific spirit or alcohol-free drink.
-
Treating “light” or “slimline” as a full ingredient description
Those names do not tell you whether two products use the same sweeteners or have the same nutrition values.
Check the exact pack’s ingredients, sweetener wording and nutrition panel, especially if you avoid a particular ingredient.
-
Using mixer size to judge alcohol content
The spirit measure and its ABV affect the alcohol in the finished drink; a 150ml tonic portion does not set either of them.
Measure the spirit separately if you add one. For a drink without alcohol, use the mixer on its own or with an alcohol-free addition.
Mixer brands and their formats
These brand references describe particular mixer ranges, not every product made by each brand or the products offered in the Joybuy selection below.
Fever-Tree
Tesco Groceries lists several Fever-Tree tonic variants in 150ml portions, including Indian and light Indian styles.
- Fever-Tree’s suggested long drink combines 50ml of spirit with 150ml of mixer, giving a reference point for portion size.
- Check the individual variant’s flavour, ingredients and nutrition label; a light variant is not a single recipe shared across the range.
Schweppes
Tesco Groceries lists standard and Slimline Schweppes tonic in 12 × 150ml packs.
- The individual 150ml portions suit shoppers planning a drink that uses that amount of mixer.
- Standard and Slimline are distinct products; check the current pack for ingredients and nutrition information.
Fentimans
Fentimans describes 200ml tonic bottles, including Premium Indian and Naturally Light variants.
- Fentimans describes citrus and herbal notes in its Premium Indian Tonic Water, giving shoppers a more specifically described flavour option.
- A 200ml bottle exceeds the 150ml mixer portion in Fever-Tree’s suggested serve; decide whether you would use the extra mixer.
Britvic
Britvic’s 2016 range announcement described Indian Tonic and Low Calorie Indian Tonic in 125ml bottles and 150ml cans.
- The announced formats show how Britvic has approached smaller mixer portions.
- Check the format and product details on a current listing before making a selection based on that older range announcement.

Fever-Tree Indian Tonic Water 8 × 150ml
A 150ml portion matches Fever-Tree’s suggested mixer amount for a long drink made with 50ml of spirit.

Questions about mini mixers
Is 150ml of mixer enough for one drink?
It can be: Fever-Tree suggests 150ml of mixer with 50ml of spirit for a long drink. If you prefer a different ratio or use a larger glass, decide by the amount of mixer you actually pour.
Should I choose 150ml cans or 200ml bottles?
Choose by your usual mixer portion. A 150ml pack fits Fever-Tree’s suggested long-drink serve, while a 200ml bottle gives you more mixer if that is what you normally use; otherwise, some may be left after one drink.
Do light and slimline tonics have the same ingredients?
No single recipe applies to every light or slimline tonic. Read the current product’s ingredients, sweetener wording and nutrition panel rather than relying on the style name.
Can I serve tonic without alcohol?
Yes. Tonic water is a soft drink and can be served without a spirit. If you do add alcohol, the mixer’s size alone does not tell you the finished drink’s alcohol content; the spirit measure and ABV also matter.
