Hosts serving gin or vodka with tonic
A 12 × 150 ml tonic pack gives you individually portioned mixers for those planned drinks. Decide how many guests will want tonic before choosing between regular and slimline.
Who is buying the mixers?
Hosts offering a no-sugar tonic
Schweppes Slimline Tonic Water is a no-sugar option, but its listed ingredients include aspartame and a source of phenylalanine. Check the current pack against guests’ ingredient requirements.
Hosts planning several kinds of drink
Tonic, lemonade and ginger mixers serve different menus. Count the expected drinks by type rather than assuming one case of tonic will suit everyone.
What should you check?
Start with the drinks you intend to serve, then check the number of portions and the ingredients in each mixer.
| Priority | What to check | Your needs |
|---|---|---|
| Drink pairing | Schweppes describes Indian tonic for gin or vodka; Tesco describes its ginger beer for mixing with rum. Joybuy describes Schweppes Original Lemonade for drinking alone or mixing with spirits. | Are most drinks gin or vodka with tonic, or would lemonade or a ginger mixer match the planned menu better? |
| Sugar and sweeteners | For its 12 × 150 ml packs, Tesco Groceries lists 7.4 g sugars and 32 kcal per serving for Schweppes regular tonic, versus 0 g sugars and 3 kcal for Slimline. Check the sweeteners and ingredients on the pack too. | I’d like guests to have a choice of tonic formulations without assuming that a no-sugar drink suits everyone. |
| Portions | A 12 × 150 ml pack totals 1.8 litres and provides 12 portions if you use one can per drink. Count expected serves separately for each mixer type. | Will one case cover the drinks people are likely to make, or do I need more than one flavour or pack? |
| Ingredients | Joybuy’s listings for Schweppes Slimline Tonic Water and Original Lemonade declare aspartame and a source of phenylalanine. Confirm ingredients and allergen information on the pack being served. | Some guests may have ingredient restrictions, so I need to check the particular mixer rather than rely on its brand name. |
What can catch you out?
-
Counting a case as enough for every kind of drink
Twelve 150 ml portions cover one mixer choice, not twelve portions of tonic plus twelve of lemonade.
Estimate serves by drink type before ordering. If preferences are mixed, plan an alternative to the dominant mixer.
-
Assuming slimline tonic has no ingredient considerations
Schweppes Slimline Tonic Water has no sugar in Tesco’s listing, but the Joybuy listing declares aspartame and a source of phenylalanine.
Read the current pack label and offer another suitable mixer when guests’ ingredient requirements call for one.
-
Planning around a mixer without checking availability
Tesco Groceries listed its Schweppes Ginger Beer 12 × 150 ml pack as out of stock on 2 October 2026. A ginger-led menu needs an available option.
Check the current pack size, stock and delivery options before relying on a particular product for the party.
-
Using an online ingredient list as the final label
Product formulations and listings can change, which matters when guests have allergies or ingredient restrictions.
Check the ingredients and allergen statement on the cans you actually serve.

Mixer formats for different drinks
This order considers the 12 × 150 ml format first, then different ingredient and menu needs; it is not a taste or sales ranking. Product descriptions come from Tesco Groceries and Joybuy. The Joybuy entry below is an original platform listing, not a linked replacement for a Tesco product.

Common questions
Is one case of 12 enough for a Christmas party?
A 12 × 150 ml case provides 1.8 litres, or twelve mixer portions if each drink uses one can. Count expected drinks by mixer type: one tonic case will not also cover guests choosing lemonade or a ginger drink.
Should I choose regular or slimline tonic?
Choose by the formulation your guests want, not by the pack count alone. Tesco Groceries lists 7.4 g sugars and 32 kcal per 150 ml serving for Schweppes regular tonic, compared with 0 g sugars and 3 kcal for Slimline; the Slimline listing also declares aspartame and a source of phenylalanine.
Can ginger beer replace tonic for every drink?
Ginger beer is a separate choice for a ginger-led menu. Tesco Groceries describes Schweppes Ginger Beer for mixing with rum, while its tonic listing describes gin or vodka pairings. Check which drinks guests actually want before choosing either mixer.
What should I check for guests with ingredient restrictions?
Check the ingredients and allergen statement on each current pack before serving. The Joybuy listings for Schweppes Slimline Tonic Water and Original Lemonade declare aspartame and a source of phenylalanine; do not assume other mixers have the same formulation.
