A 12 x 150ml tonic pack is worth considering if you regularly make single drinks and want 12 individually portioned serves; Tesco Groceries lists regular and Slimline Schweppes in that format. For less frequent use, compare a smaller multipack. If you expect to make several drinks close together, a larger bottle may suit you, provided its after-opening instructions fit your plans.
Twelve separate 150ml portions let you open one mixer at a time rather than relying on a larger opened bottle. Tesco Groceries lists Schweppes tonic in this pack format; consider how often you would use all 12 portions.
Tesco Groceries lists both regular and Slimline Schweppes in 12 x 150ml packs. If the recipe matters as much as the portion size, compare the exact variants’ ingredients and nutrition labels.
If matching a tonic to your usual spirit matters more than getting exactly 12 portions, consider other pack counts. Tesco’s Fever-Tree listing suggests its Premium Indian tonic with gin, vodka or vermouth, while Fentimans suggests its Premium Indian tonic with London Dry gin.
Start with the number and size of portions you will use, then compare the particular recipe and any instructions for an opened bottle.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check both the unit count and volume: Tesco Groceries lists Schweppes 12 x 150ml and Tesco own-label 6 x 250ml options. | I usually make one drink at a time, so I want a portion size I am likely to use when I open it. |
| Pack count | Confirm the count on the exact variant. Tesco Groceries also lists Fever-Tree in 15 x 150ml packs, while Fentimans lists Naturally Light in 200ml and 4 x 200ml formats. | Would I use 12 portions, or would a smaller multipack better match how often I make drinks? |
| Recipe | Compare ingredients and nutrition per 100ml on the specific regular, Slimline or light tonic; names alone do not describe identical recipes. | I want to choose a flavour and ingredient list that suit my preferences, not assume that similarly named light variants are the same. |
| Spirit pairing | Read the variant’s flavour description and serving suggestions. Tesco suggests Fever-Tree Premium Indian with gin, vodka or vermouth; Fentimans suggests its Premium Indian with London Dry gin. | If I usually mix one particular spirit, its flavour pairing matters more to me than an exact case count. |
| After opening | Check storage and use-by guidance for larger bottles. Tesco’s Fever-Tree 500ml listing says to refrigerate after opening and consume within three days. | For occasional drinks, I would rather open an individual portion than commit to finishing a larger bottle soon. |
Tesco Groceries lists Schweppes in 12 x 150ml packs but also lists other brands and own-label tonics in different counts and sizes. A familiar brand name does not identify the pack format.
Filter by unit count and container size before comparing variants.
A larger bottle brings after-opening storage instructions into the decision. Tesco’s Fever-Tree 500ml listing says to refrigerate it after opening and consume it within three days.
Choose individual portions if you are unlikely to use a larger bottle within its stated window; check the instructions on the bottle you buy.
Variant names do not tell you whether ingredients, sweeteners, flavour or nutrition match across brands.
Compare the current ingredient list and per-100ml nutrition information for the exact variants you are considering.
These examples help distinguish pack formats and recipes; check the exact product listing when you choose.
A direct option for the requested pack count: Tesco Groceries lists regular Tonic Water and Slimline Tonic Water in 12 x 150ml packs.
A range to consider when the tonic variant or spirit pairing matters more than an exact 12-pack.
Fentimans describes its Premium Indian tonic as herbal and citrus-led, and suggests pairing it with London Dry gin.
Britvic has documented tonic in larger wholesale bottles and, separately, retail cans; those announcements describe formats at their launch dates.
Tesco own-label mixers provide a different portion-size option from the requested case of 12.
These options include 12 x 150ml Schweppes tonic for the case-of-12 decision and Fever-Tree multipacks with eight or fifteen 150ml portions if a different count suits you.

Consider this pack if you want twelve separate 150ml portions of the Slimline variant for single drinks. Check its current ingredient and nutrition label when comparing it with regular tonic.

This regular Indian tonic matches the requested count of twelve 150ml portions. Check the current listing or pack if you need a particular container type, as the product information describes the units inconsistently as cans and bottles.

Eight 150ml portions offer a smaller pack if twelve would be more than you expect to use. This is not a case of 12; compare its current nutrition label with the particular standard tonic you would otherwise buy.

Choose this eight-portion format if you want individual 150ml serves but expect to use fewer than a case of 12. Compare the Indian tonic’s flavour description with the spirit you usually mix.

This pack has individually portioned 150ml tonic but contains fifteen units, rather than the requested twelve. Check that the larger count and the exact variant’s ingredients suit your plans.
It can be if you regularly make single drinks and will use twelve separate portions. Tesco Groceries lists regular and Slimline Schweppes tonic in 12 x 150ml packs. If drinks are occasional, compare a smaller multipack and check the case’s best-before date.
Consider a larger bottle when you expect to make several drinks within its after-opening window. For example, Tesco’s Fever-Tree 500ml listing says to refrigerate it after opening and consume it within three days. Check the instructions for the exact bottle you choose.
Compare the ingredient list and nutrition per 100ml for the exact variants, as their formulations need not match. Tesco’s Fever-Tree Premium Indian listing gives 30 kcal and 7.4g sugars per 100ml; Fentimans describes its Naturally Light tonic as having 30% fewer calories than its own Premium Indian tonic. That brand comparison does not apply to other light tonics.
