Who is each format for?

The likely drinks menu is a useful starting point: it determines whether a shared bottle will be used and which tonic flavour to offer.

Hosts serving one main mixed drink

If several guests will choose the same tonic, a shared bottle can serve more than one drink. Sainsbury’s lists Fever-Tree Refreshingly Light tonic in a 500ml glass bottle; refrigerate it after opening and consume it within three days.

Hosts setting out individual serves

Separate bottles let guests open their mixers when their drinks are made. HB Clark lists Fentimans Indian Tonic Water as a case of 24 × 200ml glass bottles, so check whether that quantity fits your gathering.

Hosts offering a choice of tonic styles

A classic tonic, a botanical option and a slimline option address different flavour or nutrition preferences. Fentimans describes citrus, herbal and lemongrass notes in its Indian tonic; Tesco lists 0g sugars and 3kcal per 150ml serving for Schweppes Slimline Tonic Water. Check the container of each exact pack if glass is essential.

What should you check before buying?

Start with the spirits and number of serves, then check the exact pack’s container and label.

Priority What to check Your needs
Spirit and flavour Check the tonic’s stated pairing and flavour profile. Fever-Tree positions its Premium Indian tonic for gin, vodka and fortified wines; Fentimans recommends its citrus-herbal Indian tonic with London Dry gin. I want a tonic that fits the drinks I am making, rather than using one pronounced flavour with every spirit.
Bottle size Compare a shared 500ml bottle with individual 200ml bottles. Sainsbury’s says its listed Fever-Tree 500ml bottle should be refrigerated after opening and consumed within three days; HB Clark lists Fentimans 200ml bottles in a case of 24. Several guests may choose the same mixer, or I may need separate bottles for different drinks without opening them all at once.
Glass packaging Confirm the material on the exact product page or pack. Sainsbury’s identifies its Fever-Tree 500ml bottle as glass, while Tesco’s Fever-Tree 15 × 150ml listing refers to a can. Glass bottles matter for my table, so the brand name or serving size alone is not enough to choose the pack.
Label information Read the exact pack for ingredients, allergens and date marking. For a no-sugar option, Tesco lists Schweppes Slimline at 0g sugars and 3kcal per 150ml serving; confirm its container separately. If guests have dietary requirements, I need to check the product they will actually be served, not assume all versions of a tonic have the same recipe.

What is easy to overlook?

  • Assuming a familiar brand’s multipack is glass

    Container material can change between packs. Sainsbury’s lists a 500ml Fever-Tree glass bottle, but Tesco’s Fever-Tree 15 × 150ml listing refers to a can.

    Check the packaging description for the exact pack before ordering.

  • Opening a shared bottle without planning the serves

    A larger bottle is less useful if guests choose different mixers. Sainsbury’s says its listed Fever-Tree 500ml bottle must be refrigerated after opening and consumed within three days.

    Estimate how many people will want the same tonic before deciding how many shared bottles to open.

  • Choosing slimline tonic without checking its flavour

    Sugar information does not tell you whether a tonic suits the spirit or the guest’s flavour preference. Fentimans describes a citrus-herbal Indian tonic, while Tesco’s Schweppes Slimline listing provides nutrition information for that specific product.

    Choose the flavour for the drinks menu, then check the exact pack’s nutrition and ingredients where they matter to guests.

Brand and product-line references

These references describe particular products and packs, not every mixer or container sold under each brand.

Fever-Tree

Fever-Tree positions its Premium Indian Tonic Water for gin, vodka and fortified wines. Sainsbury’s lists a separate 500ml Refreshingly Light tonic in a glass bottle.

  • The Sainsbury’s 500ml glass format can be shared across serves.
  • Refrigerate that bottle after opening and consume it within three days; check other Fever-Tree packs individually for glass packaging.

Fentimans

Fentimans describes its Indian Tonic Water as citrus-herbal with lemongrass notes and recommends it with London Dry gin.

  • HB Clark lists individual 200ml glass bottles.
  • That listed format is a case of 24 bottles, which may exceed the quantity needed for a small party.

Schweppes

Tesco lists Schweppes Slimline Tonic Water with 0g sugars and 3kcal per 150ml serving.

  • The listed nutrition values offer a product-specific comparison for guests asking about sugar.
  • Confirm the exact pack’s container before choosing it for a glass-bottle table.

Britvic

British Hypermarket lists Britvic Indian Tonic Water as a 200ml bottle and describes citrus notes.

  • The listed bottle size is relevant when planning individual serves.
  • Check the exact pack’s material if glass is required.

Joybuy mixer option

This cocktail mixer is a shared-bottle option for a dinner party, rather than one of the tonic-water packs discussed above. Check its exact cocktail recipe before planning the drinks.

Fever-Tree Passionfruit Martini Mixer 500ml product image

Fever-Tree Passionfruit Martini Mixer 500ml

This 500ml glass-bottle cocktail mixer is a shared-format option. Check the bottle’s cocktail name and intended spirit before choosing it: the product information differs between a passionfruit martini mixer for vodka and a classic margarita mixer for tequila. Read the current ingredients and allergen label before serving guests with dietary requirements.

Common questions

Should I buy one 500ml tonic bottle or individual 200ml bottles?

Choose a shared 500ml bottle if several guests will have the same tonic; individual 200ml bottles give you unopened serves when preferences differ. Sainsbury’s says its listed Fever-Tree 500ml glass bottle should be refrigerated after opening and consumed within three days. HB Clark lists Fentimans 200ml glass bottles in a case of 24.

How can I check a mixer for a guest with dietary requirements?

Read the label on the exact pack you will serve, particularly its ingredients and allergen information. UK food-labelling guidance from the Department for Environment, Food & Rural Affairs and Food Standards Agency also identifies date marking as information to check on pre-packed food.

Does a 150ml tonic multipack necessarily contain glass bottles?

No. Pack formats differ even within one brand: Sainsbury’s identifies a Fever-Tree 500ml glass bottle, while Tesco’s Fever-Tree 15 × 150ml listing refers to a can. Check the container material for the specific multipack.

Can I put empty glass mixer bottles out for household recycling?

In England, Department for Environment, Food & Rural Affairs guidance says household dry recyclable collections include glass from 31 March 2026. Follow your local council’s instructions for putting bottles out; do not assume England’s collection rules describe arrangements elsewhere in the UK.
