For a first food shop, a standard 12 × 150ml tonic pack suits separate drinks when zero sugar is not a requirement; choose Slimline if zero sugar matters, after checking its aspartame and phenylalanine statement. A larger bottle is worth considering if you expect to use several servings soon, while botanical tonics may come in different pack counts.
A 12 × 150ml pack gives you separate portions for drinks on different occasions. If you prefer a larger bottle, consider how soon you will use it after opening: Sainsbury's says its 1L tonic should be refrigerated and used within three days.
Schweppes Slimline 12 × 150ml tonic lists 0g sugars and 2 kcal per 100ml, but contains aspartame and carries a phenylalanine statement. Compare both the nutrition panel and ingredients rather than relying on the word ‘Slimline’.
Fever-Tree and Fentimans describe citrus and botanical notes in their Indian tonics. If that flavour profile matters more than buying exactly 12 portions, check the available pack count before choosing one.
Start with the number and size of portions you expect to use, then compare the nutrition panel, ingredients and stated flavour profile.
| Priority | What to check | Your needs |
|---|---|---|
| Pack and portions | Check the unit count, volume per unit and container type. A 12 × 150ml pack contains 1.8L in total; Sainsbury's says its 1L own-label bottle must be refrigerated and used within three days of opening. | I expect drinks on separate occasions and want individual portions, or I can use several servings from an opened bottle soon. |
| Sugar and sweeteners | Compare values per 100ml and read the ingredients. Sainsbury's lists standard Schweppes tonic at 7.4g sugars and 32 kcal per 150ml can; its Slimline 12-pack lists 0g sugars and 2 kcal per 100ml and contains aspartame. | Zero sugar matters to me, or I would rather choose by flavour and check the sugar content of the particular tonic. |
| Flavour | Look for the stated flavouring and suggested pairing. Fever-Tree describes bitter-orange oils in its Premium Indian tonic; Fentimans describes lemon oil and lemongrass in its Premium Indian tonic. | I have a particular gin, vodka or alcohol-free mixed drink in mind and want to decide whether a botanical tonic suits it. |
| Ingredient statements | Read the current pack label for sweeteners, quinine and any statements relevant to ingredients you avoid. Schweppes Slimline contains quinine and states that it contains a source of phenylalanine. | I need to check a specific ingredient rather than assume that ‘slimline’ or ‘tonic’ tells me everything in the drink. |
Tesco lists Fever-Tree tonic in 8 × 150ml and 15 × 150ml packs as well as 500ml bottles, so pack names alone may conceal a different quantity.
