Hosts serving different preferences
Individual cans let guests choose when to open a drink. If some want classic tonic and others want a lighter style, consider whether two smaller packs would be more useful than one larger pack of a single flavour.
Who is choosing mixer cans?
The useful pack size and mixer style depend on what guests are likely to drink, not just the number invited.
Hosts planning tonic-led drinks
Match the tonic to the drinks you intend to make. Fever-Tree describes its Mediterranean style as a pairing for citrus or herbaceous gin, vodka and vermouth; a classic tonic offers a different flavour choice.
Hosts checking sugar and sweeteners
Schweppes Slimline has 0g sugars per 150ml serving but contains aspartame and carries a source-of-phenylalanine warning, according to Sainsbury's product listing. Joybuy lists 4.2g sugars per 100ml for Fever-Tree Refreshingly Light Mediterranean, so the two are not interchangeable no-sugar options.
What matters when choosing a pack?
Start with likely demand for tonic, then decide whether guests need a different flavour or a particular sugar and sweetener choice.
| Priority | What to check | Your needs |
|---|---|---|
| Portions and pack size | Count the 150ml cans and estimate how many tonic serves you need. The listed Britvic 24-pack contains 3.6 litres; Schweppes 12-packs contain 1.8 litres, and Fever-Tree eight-packs contain 1.2 litres, according to Amazon UK, Sainsbury's and Tesco listings. | I want enough individual portions for guests who will actually drink tonic, without opening a large bottle at the start. |
| Sugar and sweeteners | Read the nutrition and ingredients panels for the exact variant. Sainsbury's lists 0g sugars per 150ml serving for Schweppes Slimline, alongside aspartame and a source-of-phenylalanine warning; Joybuy lists 4.2g sugars per 100ml for Fever-Tree Refreshingly Light Mediterranean. | Some guests may want a no-sugar tonic, while others may prefer an option without artificial sweeteners. I need to check which distinction matters to them. |
| Flavour | Decide whether classic tonic or a citrus-and-herb Mediterranean style fits the planned drinks. An eight-can botanical pack can provide a second choice without making it the only mixer. | If guests have different tastes, I would rather offer a distinct second flavour than assume everyone wants the same tonic. |
| Drink type | Check the product name, ingredients and ABV. Tesco lists ready-to-drink spirit-and-mixer cans separately from non-alcoholic mixer products. | I want to know whether a can is mixer alone or already contains alcohol before putting it on the drinks table. |
Common buying mistakes
-
Buying one distinctive tonic for everyone
A citrus-and-herb tonic is a deliberate flavour choice; it may not fit every planned drink or guest preference.
If preferences are unclear, consider a classic tonic as the main pack and a smaller botanical pack as a second choice.
-
Assuming ‘light’ and ‘slimline’ mean the same thing
Sainsbury's lists Schweppes Slimline as containing 0g sugars per 150ml serving, but also as containing aspartame. Joybuy lists sugars in Fever-Tree Refreshingly Light Mediterranean.
Compare the exact nutrition panel, ingredients and warnings instead of relying on the wording on the front of the pack.
-
Comparing packs without counting the cans
An eight-pack, a 12-pack and a 24-pack provide different amounts of mixer even when every can holds 150ml. A larger case may also leave unopened cans if few guests choose tonic.
Estimate likely demand, then compare can count and total volume before choosing a pack.
-
Assuming every mixer search result is alcohol-free
Tesco's ready-to-drink listings include spirit-and-mixer cans as well as separate mixer products.
Check the exact product name and ABV before serving a can as a non-alcoholic mixer.
Brands and retailers to recognise
These ranges and retailer listings provide useful points of comparison; a brand's inclusion here does not mean every product in its range is a canned multipack.
Fever-Tree
Tesco and Sainsbury's list eight-can, 150ml tonic multipacks, including Mediterranean and Indian styles.
- The Mediterranean style gives hosts a citrus-and-herb alternative to classic tonic.
- An eight-can pack provides 1.2 litres, so check whether one pack covers the expected demand.
Schweppes
Sainsbury's lists standard and Slimline tonic in 12 × 150ml cans.
- The Slimline listing states 0g sugars per 150ml serving.
- Slimline contains aspartame and carries a source-of-phenylalanine warning; standard Schweppes tonic contains sugar and sweetener.
Britvic
Amazon UK lists Britvic Indian Tonic Water as a 24 × 150ml can case.
- The case provides 3.6 litres of one tonic style when several guests are likely to choose it.
- Britvic's standard Indian tonic ingredients include sugar and saccharin, according to Britvic Mixers & Juices.
Fentimans
Fentimans has a tonic and mixer range, including Connoisseurs Tonic Water.
- Fentimans describes its Connoisseurs Tonic as a botanical style.
- Check the container and pack format if individual cans are essential for the book club.
Tesco
Tesco's mixer listings include Fever-Tree 8 × 150ml and Schweppes 12 × 150ml canned packs.
- Its listings allow a comparison of these branded pack formats.
- Check the brand and exact variant rather than assuming a retailer listing describes an own-brand product.
Sainsbury's
Sainsbury's lists branded Fever-Tree and Schweppes tonic cans alongside its own-brand tonic and soda in one-litre bottles.
- Its Schweppes Slimline listing includes serving-level nutrition and the sweetener warning.
- Check the container size and type: a one-litre bottle does not meet a need for individual cans.
Joybuy mixer-can options
These multipacks offer tonic choices in different styles and a ginger ale alternative. Check the flavour and pack size against the drinks planned for your book club.

Schweppes Slimline Tonic Water, 12 × 150ml
Twelve individual 150ml portions suit a group that wants a no-sugar tonic choice. Sainsbury's lists 0g sugars per 150ml serving; this variant contains aspartame and carries a source-of-phenylalanine warning, so check the can label against guests' needs.
No image available
Fever-Tree Refreshingly Light Mediterranean Tonic Water, 8 × 150ml
The eight 150ml cans offer a Mediterranean tonic for guests who want a distinct citrus-and-herb style. Joybuy lists 17 kcal and 4.2g sugars per 100ml, so this is not a sugar-free choice; the pack provides 1.2 litres in total.
No image available
Fever-Tree Indian Tonic Water, 8 × 150ml
This eight-can Indian tonic pack offers individual 150ml portions when a classic tonic style fits the planned drinks. It contains sugar rather than providing a no-sugar alternative; check whether eight cans will cover the likely tonic drinkers.
No image available
Canada Dry Ginger Ale Mini, 12 × 150ml
Twelve individual 150ml cans provide a ginger ale choice for guests who do not want tonic. Ginger ale has a different flavour, so check that it suits the drinks you plan to serve; this product contains sugar and sweeteners.
Book-club mixer questions
How many 150ml mixer cans should I plan for a book club?
Start with the guests likely to drink that mixer, then estimate how many 150ml portions they may use. Eight cans provide 1.2 litres, 12 provide 1.8 litres and 24 provide 3.6 litres; actual use will depend on the drinks served and guests' preferences.
Is slimline tonic suitable for everyone avoiding sugar?
Do not assume so. Sainsbury's lists 0g sugars per 150ml serving for Schweppes Slimline, but its ingredients include aspartame and its label carries a source-of-phenylalanine warning. Check the exact can label and offer another choice if that warning matters to a guest.
Should I check the can label as well as the retailer listing?
Yes. Read the physical pack's ingredients, nutrition information and any warnings before serving, particularly when a guest has asked about a specific ingredient. Check the exact variant rather than relying on a different tonic in the same brand range.
Are all cans shown in mixer searches alcohol-free?
No. Tesco also lists ready-to-drink spirit-and-mixer cans. Check the product name and ABV to distinguish a mixer on its own from a premixed alcoholic drink.
Can tonic be served without a spirit?
Yes, tonic can be served on its own as a soft drink. Its flavour and sweetener ingredients vary by product, so offer water or another soft drink too if you do not know whether everyone wants tonic.
