Choose a 12 × 150 ml slimline tonic if you want a zero-sugar tonic and aspartame is suitable for your guests. Standard tonic suits drinks calling for quinine bitterness, while lemonade offers a lemon-flavoured mixer that guests can also drink on its own. If botanical flavour matters more than an exact count of 12, check alternative pack sizes before buying.
A 12 × 150 ml case gives you 12 separately packaged portions and 1.8 litres in total. It is worth checking how many guests will want a mixer, since some may choose a soft drink on its own or use less than a full can.

Start with the number and size of individual portions, then match the drink style and ingredient list to what you plan to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Check both the unit count and volume per unit. Twelve 150 ml portions contain 1.8 litres in total; other multipacks may have a different count or can size. | I want 12 separately packaged portions, rather than simply a similar total volume. |
| Ingredients | Read the purchased pack’s sugar information, sweeteners and warnings. Schweppes Slimline Tonic Water 12 × 150 ml lists 0 g sugars per 100 ml but contains aspartame and a source of phenylalanine. | A zero-sugar tonic may suit my drinks plan, but I also need to account for guests who avoid particular ingredients. |
| Drink style | Decide whether the planned drinks call for quinine tonic or lemon-flavoured lemonade. Consider whether guests will drink the mixer on its own. | Some guests may want tonic with a mixed drink; others may prefer a standalone lemonade. |
| Serving information | Check the physical pack’s ingredients, allergen statement, best-before date and pack count before serving. | When serving a mixed group, I want the current packaging to hand so I can answer ingredient questions accurately. |
The Tesco Groceries Fever-Tree listings include 8- and 15-can packs, while the DrinkSupermarket Fentimans listing is 24 × 200 ml. Those counts change the number of unopened portions available at the buffet.
