Who is choosing the mixers?

The drinks list matters more than the number of guests: a gin-led table calls for a different second mixer from one serving dark spirits.

Hosts serving several spirits

Keep classic tonic available for gin, vodka and vermouth. If whisky, bourbon or rum is also on the menu, consider ginger ale rather than buying several similar flavoured tonics.

Hosts offering alcohol-free serves

Offer a choice of flavour profiles for guests drinking mixers over ice. Tonic brings quinine bitterness; ginger ale offers a different ginger-flavoured option.

Ingredient-conscious shoppers

Compare the exact pack labels when choosing regular, light or low-calorie tonic. Sugar and sweetener ingredients differ between products, so the name of the variant is not enough to make that choice.

What should you check before buying?

Settle the main mixer from the planned drinks, then decide whether a second flavour and a different pack format will be used.

PriorityWhat to checkYour needs
Spirit pairing Check which spirits are planned. Fever-Tree positions its Indian tonic with gin, vodka and vermouth, and its ginger ale with whisky, bourbon and rum. If I’m serving gin alongside vodka or vermouth, I want a classic tonic available. For dark-spirit drinks, I may want ginger ale as a separate choice.
Flavour Keep a plain tonic option if guests expect a conventional G&T. Fentimans suggests its Valencian Orange Tonic Water for citrus and herbaceous gins. A flavoured tonic makes sense when I know which gin it will accompany; it need not replace the plain tonic.
Sugar and sweeteners Read sugars per 100ml and the ingredients list on the exact pack. Tesco Groceries lists 0g sugars per 100ml and acesulfame K and sucralose for its Low Calorie Indian Tonic Water. If sugar or a particular sweetener matters to my guests, I need to compare formulations rather than rely on “light” or “low calorie” in the name.
Pack format Match larger bottles to mixers likely to be poured repeatedly; consider sealed 150ml cans when offering several styles. Check the storage instructions for any bottle you open. I’d rather open one main bottle than leave several partly used. Individual cans give guests a way to try a less predictable choice.
Ingredients Read the current label for the precise variant before serving anyone with an allergy, intolerance or ingredient restriction. Do not transfer a claim from another product in the range. Before I put mixers out for guests, I want to know which exact packs meet any ingredient requirements they have told me about.

What can go wrong with the mix?

  • Buying only flavoured tonic

    An orange-led tonic may suit a planned gin, but guests expecting a conventional G&T may prefer plain Indian tonic.

    Cover the classic tonic choice first, then add a flavoured option if it fits a drink you intend to serve.

  • Assuming every “light” tonic has the same ingredients

    Lower-calorie and low-sugar variants do not necessarily use the same sugars or sweeteners. Tesco Groceries lists acesulfame K and sucralose in its Low Calorie Indian Tonic Water.

    Compare the sugars line and full ingredients list on each exact pack, particularly when a guest avoids a specific ingredient.

  • Opening every large bottle at once

    Less-used mixer styles may remain partly full after the party, and an opened bottle needs to be stored according to its label.

    Open the expected main mixer as needed and keep less predictable choices sealed until someone wants them.

    Sainsbury’s Diet Indian Tonic Water 1L instructs shoppers to refrigerate it after opening and use it within three days.

  • Applying one variant’s ingredient information to a whole range

    Products sold under the same brand can have different recipes, and ingredients can change.

    Check the current label of each product before serving it to a guest with an allergy, intolerance or ingredient restriction.

Which brands offer relevant options?

These ranges illustrate different mixer choices; check the exact variant and pack rather than treating a brand name as a flavour or ingredient guarantee.

Fever-Tree

Offers Indian tonic for classic serves and ginger ale for a different drinks route.

  • Its Joybuy Indian tonic listing names gin, vodka and vermouth pairings; Fever-Tree positions its ginger ale with whisky, bourbon and rum.
  • Regular and Refreshingly Light tonics are distinct variants. Compare their current nutrition and ingredient labels rather than assuming “light” means sugar-free.

Schweppes

A classic tonic reference for guests who want a dry, bitter-sweet flavour.

  • Tesco Groceries describes its Indian Tonic Water as a quinine-and-lemon tonic; Joybuy lists a 12 x 150ml can pack.
  • Check whether you are buying regular Indian tonic or a different variant such as Slimline, since their ingredient choices should not be treated as identical.

Fentimans

Offers several tonic flavours for a drinks table with a planned second tonic.

  • Fentimans suggests its Valencian Orange Tonic Water for citrus and herbaceous gins.
  • That flavour-led pairing does not make it a substitute for plain tonic when guests expect a conventional G&T.

Britvic

A reference for classic and zero-sugar Indian tonic variants.

  • Britvic announced classic and zero-sugar tonic cans for grocery retail in September 2023.
  • That launch announcement does not establish which packs or recipes a retailer carries now; check the current product label.

Tesco

An own-label option when the ingredient profile of a low-calorie Indian tonic is a deciding factor.

  • Tesco Groceries lists 0g sugars per 100ml for its Low Calorie Indian Tonic Water.
  • That product lists acesulfame K and sucralose, so check the label if either sweetener matters to a guest.

Sainsbury’s

An own-label range with standard and diet Indian tonic choices in 1L bottles.

  • The separate standard and diet listings allow shoppers to compare the exact variant they intend to serve.
  • Sainsbury’s advises reading the product label because ingredients can change; its diet tonic also carries instructions for storage after opening.

Joybuy mixer options

These Joybuy packs cover classic and flavoured tonics, Slimline tonic and ginger ale for different drinks on the party menu. The small-can formats also let you keep a less-used style sealed until it is needed.

Fever-Tree Indian Tonic Water 8 x 150ml

Fever-Tree Refreshingly Light Mediterranean Tonic Water 8 x 150ml

Party mixer questions

How many sparkling mixer styles should I put out?

Start with classic Indian tonic if gin, vodka or vermouth is on the drinks list. Add ginger ale for planned dark-spirit drinks or a flavoured tonic for a particular gin; put out both only if guests are likely to use them.

Does “low calorie” mean a tonic is sugar-free?

No. A light or low-calorie name does not settle the sugar or sweetener question. Tesco Groceries lists 0g sugars per 100ml and acesulfame K and sucralose for its Low Calorie Indian Tonic Water; check the sugars line and ingredients on any other exact pack separately.

Should I choose cans or 1L bottles for the party?

Use a larger bottle for a mixer you expect to pour repeatedly, and consider individual cans for less predictable flavours. Follow each opened bottle’s storage instructions: Sainsbury’s Diet Indian Tonic Water 1L says to refrigerate it and use it within three days of opening.

Is a retailer listing enough to check ingredients for guests?

Use it to compare products before buying, then read the current physical label before serving someone with an allergy, intolerance or ingredient restriction. Sainsbury’s advises that ingredients can change, so a listing or another variant’s label should not stand in for the pack being served.
