Hosts making a few mojitos
A four-unit pack can suit a planned cocktail serve without committing to a larger tonic multipack. Sainsbury’s lists Fever-Tree Mojito Mixer as 4 x 150ml and gives a serve using 50ml rum with one 150ml portion of mixer.
Who is each format for?
Shoppers planning individual tonic serves
If 150ml portions matter more than buying exactly four units, compare the larger Fever-Tree and Schweppes tonic multipacks listed by Sainsbury’s. Check the pack count against the number of drinks planned.
Shoppers choosing a particular flavour
If the flavour of the mixer is central to the drink, consider whether you want a balanced tonic or a distinct citrus note. Fentimans describes its Connoisseurs Tonic as balanced and its Oriental Yuzu Tonic as a pairing for strong London Dry or botanically rich gins.
What should you check before choosing?
Start with the drink you intend to make, then match the pack count and portion size to the number of serves. Check nutrition and packaging on the exact product rather than relying on a range name.
| Priority | What to check | Your needs |
|---|---|---|
| Pack and portions | Check the number of units, volume per unit and any stated serving ratio. Sainsbury’s lists Fever-Tree Mojito Mixer at 4 x 150ml with a 50ml rum and 150ml mixer serve; its listed tonic alternatives include larger packs. | I’m making a limited number of drinks and want the pack size to match the occasion, rather than leaving several mixer portions unused. |
| Drink and flavour | Check whether the product is a flavoured cocktail mixer or a tonic, then read its suggested pairings. Fentimans positions Oriental Yuzu Tonic for strong London Dry or botanically rich gins. | For a mojito, I want a lime-and-mint cocktail mixer; for a gin and tonic, I may want the gin to remain prominent or deliberately add citrus flavour. |
| Nutrition and ingredients | Compare sugars and energy per 100ml on the same basis, alongside the ingredients and intended serving volume. A product labelled “light” is not necessarily sugar-free. | I’d rather compare the exact recipes than assume two tonics with similar names contain the same sugar or sweeteners. |
| Pack presentation | Confirm the container material as well as the unit count and individual volume. A four-unit listing does not, by itself, establish that the portions are cans. | If cans matter for serving or storage, I need that detail confirmed for the exact pack I’m buying. |
| Retailer assortment | Check the exact flavour and pack size with your chosen retailer. Fever-Tree notes that stores do not all stock its full range. | I’m planning a particular drink, so a different flavour or pack format would change what I need to buy. |
Mistakes to avoid
-
Assuming four units means four cans
A pack count tells you how many portions it contains, not what the containers are made of. That distinction matters if you have a particular serving or storage plan.
Check the container description on the exact product page and the pack label before relying on a can format.
-
Swapping tonic for a dedicated cocktail mixer
Sainsbury’s describes Fever-Tree Mojito Mixer as a flavoured cocktail mixer with a rum serve. A tonic intended for gin, vodka or vermouth serves a different purpose.
Choose by the drink you plan to make, then check the product’s flavour and suggested serve.
-
Reading “light” as “sugar-free”
Sainsbury’s lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Indian Tonic. A label term cannot replace the nutrition panel.
Compare the exact products per 100ml and read the ingredients if particular sweeteners matter to you.
-
Planning around an entire brand range
Fever-Tree says not every store stocks its full range, so a specific flavour and pack size may require a retailer-level check.
Confirm the chosen retailer’s exact listing and availability before planning drinks around it.
Brands and retailers to compare
These references help distinguish cocktail mixers, tonics and pack formats; they do not imply that every named product is available from Joybuy.
Fever-Tree
Sainsbury’s lists a 4 x 150ml Mojito Mixer alongside larger Premium Indian and Refreshingly Light Indian tonic multipacks.
- The Mojito Mixer listing includes a specific rum-and-mixer serve.
- Do not assume that its listed tonic multipacks meet a strict four-unit requirement.
Schweppes
Sainsbury’s lists Schweppes Tonic Water in a 12 x 150ml format for drinks including gin or vodka serves.
- The listing specifies individually portioned 150ml units.
- The 12-unit pack exceeds a four-unit requirement; check its ingredients if sweetener choice matters.
Fentimans
Fentimans describes Connoisseurs Tonic as balanced and Oriental Yuzu Tonic as a citrus-led pairing for particular gins.
- The two tonics offer different manufacturer-described flavour directions.
- Check the exact retail pack format rather than assuming either tonic comes as four cans.
Britvic
Britvic announced classic and zero-sugar Indian Tonic Water in six-packs of 330ml cans for grocery retail in September 2023.
- The announced format offered a larger individual can than the 150ml portions discussed here.
- That announcement does not establish current availability or a four-pack format.
Tesco
Tesco’s tonic-and-mixers assortment lists Fever-Tree and Schweppes products in differing multipack sizes.
- Its listings let shoppers check the exact pack format within one retailer’s assortment.
- Confirm the selected product and availability rather than assuming a brand comes in every pack size.
Sainsbury’s
Sainsbury’s product listings describe Fever-Tree Mojito Mixer, tonic multipacks and Fentimans Classic Ginger Beer in their respective pack sizes.
- The individual listings provide details for comparing the intended drink and pack.
- Read the delivered label before relying on ingredients, which can change.
Joybuy tonic multipacks
These are portioned tonic options for shoppers who can use more than four units. Each listed pack contains 8 or 12 portions, so none is an exact four-pack substitute; check the container format where it matters.
No image available
Fever-Tree Indian Tonic Water 8 x 150ml
Consider this tonic for individually portioned spirit-and-tonic serves when eight units suit your plans. It is not a four-pack.
No image available
Fever-Tree Refreshingly Light Mediterranean Tonic Water 8 x 150ml
Consider the Mediterranean flavour direction if it suits the drink you plan to make. The pack contains eight 150ml units, so check both the nutrition panel and container details for this exact variant.
No image available
Fever-Tree Naturally Light Tonic Water 8 x 150ml
This is another eight-unit tonic option rather than a four-pack. If the light-style recipe is your reason for choosing it, compare the exact nutrition and ingredients label with other tonics.
No image available
Schweppes Slimline Tonic Water 12 x 150ml
Consider this tonic when 150ml portions are useful and a 12-unit pack fits your plans. Check the ingredients label if sweetener choice is important to you.
No image available
Schweppes Indian Tonic Water 12 x 150ml
This tonic is an option for gin or vodka serves when twelve portions are appropriate, not when exactly four are required. Confirm whether the containers are cans or bottles before choosing it for a particular presentation.
Questions about mixer packs
Does a four-pack of mixer always contain cans?
No. Four-pack describes the unit count, not the container material. Check the exact product’s packaging description and the delivered pack if cans are important to your plans.
How many serves does Fever-Tree Mojito Mixer 4 x 150ml make?
It provides four mixer portions for four serves using Sainsbury’s stated recipe of 50ml rum and 150ml mixer per drink. You would need 200ml rum in total for those four serves, plus any ice or garnish you choose to use.
Is a light tonic necessarily sugar-free?
No. Sainsbury’s lists 3.8g sugars per 100ml for Fever-Tree Refreshingly Light Indian Tonic, despite its lower-calorie comparison with Fever-Tree Premium Indian Tonic. Read the nutrition panel for the exact variant and pack.
What if I want the gin to remain prominent?
A tonic positioned as balanced may be worth considering. Fentimans describes its Connoisseurs Tonic in those terms, but that is the brand’s flavour positioning, not an independent taste result; check whether its ingredients and flavour description suit your gin.
Can I rely on an online ingredients list for a dietary decision?
Check the label on the delivered pack before consuming it. Sainsbury’s notes that product details and ingredients can change; if a particular ingredient is critical to you, contact the manufacturer for clarification.
