Choose a classic Indian tonic in 150ml cans if you want a straightforward mixer for gin, vodka or vermouth. A lighter tonic suits a different preference from a no-sugar one: Fever-Tree Refreshingly Light still contains sugar, while Schweppes Slimline uses aspartame and carries a phenylalanine-source declaration. Check the can count, ingredients and intended spirit pairing before choosing a pack.
If the cans are for gin, vodka or vermouth, start with the spirit you intend to pour. Fever-Tree describes its Indian tonic as a pairing for all three; a more distinctive botanical tonic is worth considering when its stated flavour profile suits the serve.
These labels describe different formulations. Sainsbury's lists Fever-Tree Refreshingly Light at 15kcal and 3.8g sugars per 100ml, while its Schweppes Slimline listing gives 2kcal and 0g sugars per 100ml and identifies aspartame as a sweetener.
A 150ml can matches the mixer quantity in Fever-Tree's stated 50ml spirit and 150ml mixer serve. Britvic described its 330ml can as providing two serves when it announced six-packs in September 2023; check the exact pack and can size for the occasion you have in mind.
Settle on the tonic style and ingredients first, then choose a can size and pack count that fit how you will serve it.
| Priority | What to check | Your needs |
|---|---|---|
| Spirit pairing | Read the stated pairing and flavour profile. Fever-Tree describes Premium Indian tonic for gin, vodka and vermouth; its Mediterranean tonic is described for citrus and herbaceous gins. | I want a tonic that suits the spirit I plan to serve. If I have not chosen a particular flavour pairing, a classic Indian tonic is a starting point rather than an assumption that every botanical variant will taste alike. |
| Sugar and sweeteners | Compare nutrition per 100ml as well as ingredients. Sainsbury's lists Fever-Tree Premium Indian at 36kcal and 8g sugars, Refreshingly Light at 15kcal and 3.8g sugars, and Schweppes Slimline at 2kcal and 0g sugars per 100ml. Slimline contains aspartame and declares a source of phenylalanine. | If I want less sugar than the standard Fever-Tree tonic, I still need to decide whether a tonic containing fructose meets my preference or whether I want a no-sugar formulation with a different sweetener. |
| Can and pack size | Check both the number of cans and the volume of each. The listed Fever-Tree packs include 8×150ml and 15×150ml formats; Britvic's September 2023 announcement described a 6×330ml format, with two serves per can according to Britvic. | For one planned spirit serve at a time, 150ml cans match Fever-Tree's stated mixer measure. If I expect to pour from a larger can, I should check that its serving format works for my guests. |
| Pack information | Check the can label for ingredients, relevant allergen information, nutrition, date marking and product-specific storage instructions. UK government food-labelling guidance identifies information required on pre-packed food. | I want to check the formulation and follow the instructions on the pack I actually buy, particularly when switching between standard, light and no-sugar tonic. |
Sainsbury's lists 3.8g sugars per 100ml and fructose for Fever-Tree Refreshingly Light. Its Schweppes Slimline listing instead states 0g sugars per 100ml, names aspartame and carries a phenylalanine-source declaration.
Read the nutrition panel and ingredient list together; choose between the formulations on those details, not the word on the front of the pack.
Eight 150ml cans and six 330ml cans provide different total volumes and different amounts in each opened can. Can count alone will not tell you how the pack fits your planned serves.
Compare the stated can size and count, then consider whether you want individual 150ml measures or larger cans to pour from.
Fever-Tree describes its Mediterranean tonic for citrus and herbaceous gins, whereas its Indian tonic is presented for gin, vodka and vermouth more broadly. Fentimans describes citrus and herbal notes in its Premium Indian tonic.
Decide which spirit you are serving before adding a flavour-led variant to a multipack shop.
A tonic you recognise may appear in a bottle or a different pack format. Britvic's 330ml six-pack details come from its September 2023 launch announcement, so that announcement alone does not establish the format of a pack you can buy now.
Check the product title and pack details for the container type, can count and volume before treating it as a multipack-can option.
Fever-Tree has Indian tonic multipacks in 150ml cans, alongside lighter and Mediterranean-style variants.
Schweppes has standard and Slimline tonic listings in 12×150ml multipacks.
Britvic announced classic and zero-sugar Indian Tonic Water in 6×330ml cans in September 2023.
Fentimans describes its Premium Indian tonic with Sicilian lemon oil, lemongrass and herbal infusions; it positions Connoisseurs tonic as a more restrained botanical pairing for spirits.
These options cover 150ml tonic multipacks for classic spirit serves, lighter formulations, a no-sugar formulation and a Mediterranean-style pairing. Check each product's ingredients and pack details against the serve you intend to make.

A classic Indian tonic format for gin, vodka or vermouth serves. The 150ml can matches Fever-Tree's stated measure of mixer for a 50ml spirit serve; the corresponding Sainsbury's listing gives 36kcal and 8g sugars per 100ml.
No image available
A no-sugar tonic multipack for shoppers who prefer that formulation to a light tonic containing fructose. Sainsbury's lists 2kcal and 0g sugars per 100ml; check the label for aspartame and the phenylalanine-source declaration.
No image available
A larger 150ml-can pack for shoppers seeking the named light Indian tonic rather than a no-sugar formulation. The corresponding Sainsbury's listing gives 15kcal and 3.8g sugars per 100ml and lists fructose; check the current pack label for its comparative calorie statement.
No image available
A flavour-led 150ml-can pack to consider when serving citrus or herbaceous gin. Fever-Tree also describes this Mediterranean tonic as a pairing for vodka and vermouth; check its ingredient and nutrition label rather than assuming that 'light' means sugar-free.
No image available
An eight-can light tonic option for 150ml mixer serves. If sugar or sweetener choice matters to you, compare this exact pack's nutrition and ingredient label with the other light and no-sugar options rather than treating their names as interchangeable.
It matches Fever-Tree's stated serve of 50ml spirit with 150ml mixer. If you prefer to pour more mixer or serve more than one drink from a can, check the can volume instead; Britvic described its 330ml cans as two serves in its September 2023 announcement.
No. Sainsbury's lists fructose and 3.8g sugars per 100ml for the 15×150ml Refreshingly Light Indian tonic. Its Schweppes Slimline listing states 0g sugars per 100ml, but names aspartame and declares a source of phenylalanine.
Check the ingredients, relevant allergen information, nutrition, net quantity and date marking, as well as instructions for the particular product. UK government food-labelling guidance identifies information required on pre-packed food; the can label is the place to check the pack you are using.
Follow the storage instructions on the exact pack, including any directions that apply after opening. Do not assume instructions for one tonic or container size apply to another.
