Choose a 150ml single-serve mixer if you plan one opened portion per drink: Fever-Tree's serving suggestion pairs 150ml of mixer with 50ml of spirit, and both Fever-Tree and Schweppes offer 150ml multipacks. Choose between regular, light and no-sugar tonic by checking the particular product's ingredients; add a flavoured tonic for guests who want it rather than making it the only option. If you specifically want glass mini bottles, check the packaging before buying: the established 150ml options here are chiefly cans, while Fentimans also offers a 200ml format.
Individual portions are particularly useful when guests are making different drinks or choosing different tonic styles.
A sealed portion lets you open mixer for each drink rather than leave a large bottle on the table. Fever-Tree's serving suggestion, shown by Tesco Groceries, uses 150ml of mixer with 50ml of spirit; choose a different portion if your drinks use another ratio.
Set out separately labelled choices if guests have sugar or sweetener preferences. Tesco Groceries lists Fever-Tree Light as lower in calories than its standard tonic, while Schweppes Slimline is a no-sugar option; check each pack's ingredients rather than treating the two as identical.
A botanical or garden-inspired tonic adds another flavour choice. Fever-Tree describes its Summer Garden tonic with cucumber, green apple and garden mint notes; keep a classic tonic available for guests who do not want those flavours.
Plan the drink size and number of portions first, then choose the tonic formulations and flavours you want to offer.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check the volume of each container, the pack count and whether it is a can or bottle. Tesco Groceries lists Fever-Tree and Schweppes 150ml multipacks; Fentimans lists 200ml Naturally Light tonic. | I'd like to open one mixer per drink. Fever-Tree's 50ml spirit and 150ml mixer suggestion fits that plan; a 200ml portion calls for a different serve or sharing. |
| Ingredients | Compare the nutrition information per serving or per 100ml, and read the sweetener ingredients. Tesco Groceries lists 7.4g sugar and 32kcal per 150ml for regular Schweppes tonic, versus 0g sugar and 3kcal per 150ml for Slimline. | Some guests may want a no-sugar mixer, while others may prefer a different ingredient list. I'd check the exact pack rather than assume every light tonic uses the same recipe. |
| Flavour choice | Check whether a tonic is classic, botanical or flavoured, and whether its stated flavour notes suit the drinks you plan. Fever-Tree describes cucumber, green apple and garden mint notes in Summer Garden tonic. | I want guests to have a familiar tonic choice alongside any garden-inspired flavour, especially if they are making different drinks. |
A 200ml Fentimans tonic is not a one-for-one substitute for the 150ml mixer in Fever-Tree's published serving suggestion. Pack count alone will not tell you how many drinks your plan makes.
Decide how much mixer goes into each drink before counting portions. Choose 200ml containers when your planned drinks use that volume or guests will share them.
Fever-Tree's Summer Garden tonic has cucumber, green apple and garden mint notes. Those flavours may not suit every drink or guest.
Keep a classic tonic or soda alongside a botanical or garden-inspired choice.
Light and Slimline identify different products, not a shared recipe. Tesco Groceries lists Fever-Tree Light as lower in calories than its standard tonic and Schweppes Slimline as containing no sugar.
Read the ingredient and nutrition labels for the exact variants you buy, particularly when a guest has a sweetener preference.
Compare specific formats and variants rather than assuming every product from a brand suits the same serving plan.
