Who is choosing the drinks?

Canteen managers planning a soft-drink lunch menu

Soda water and tonic water can be listed as drinks served on their own, without a spirit. Check whether the proposed menu and its presentation fit the employer’s alcohol policy.

Employees looking for a more distinctive flavour

Tonic offers bitterness, while botanical tonics and labelled non-alcoholic ready-to-drink products offer different flavour profiles. The latter also calls for a pack ABV and workplace-policy check.

Canteens comparing sugar and calorie information

Plain soda water, low-calorie tonic and light tonic have different formulations. Compare the nutrition panel and ingredients of the exact product being served rather than treating those names as equivalent.

What should you check?

Choose the type of lunch drink first, then compare its label, ingredients and serving format.

Soda water

Choose it when: The canteen wants a plain sparkling soft drink that needs no spirit.

Trade-off: It does not provide tonic’s bitter flavour; any cordial or other addition needs assessing separately.

Low-calorie tonic

Choose it when: People want tonic bitterness in a drink served without alcohol.

Trade-off: Check the sweeteners and sugar on the exact label; it is not the same drink as unsweetened soda water.

Light flavoured tonic

Choose it when: A botanical or citrus tonic flavour matters more than a plain sparkling base.

Trade-off: “Light” does not establish that a product has no sugar or calories; compare its own nutrition panel.

Non-alcoholic ready-to-drink option

Choose it when: The canteen wants a complete adult-style drink rather than a mixer served on its own.

Trade-off: Confirm the pack ABV and whether its name and presentation fit workplace policy.

PriorityWhat to checkYour needs
Alcohol and policy Check what the complete serve contains, not just the mixer. For an alcohol-adjacent ready-to-drink product, check the pack ABV and employer policy. I want a lunch drink that does not require adding a spirit and can be described clearly on the canteen menu.
Flavour Decide whether a plain sparkling drink, bitter tonic or botanical ready-to-drink flavour suits the menu. Assess additions to soda water separately. A plain fizzy drink may be enough, or I may prefer tonic bitterness without an alcoholic serve.
Nutrition Compare energy and sugars per 100 ml on the exact product. Coca-Cola Great Britain lists Schweppes Soda Water at 0 kcal and 0 g sugars; Tesco lists its low-calorie lemon tonic at 2 kcal and under 0.1 g sugars per 100 ml. I want to distinguish a plain soda water from a tonic that still contains sugar or uses sweeteners.
Ingredients Read the sweetener and ingredient list. Tesco lists acesulfame K and sucralose in its low-calorie lemon tonic; Britvic lists aspartame, saccharin and a phenylalanine-source statement for its low-calorie Indian tonic. Ingredient information needs to be clear so I can choose a drink that fits my preferences or requirements.
Serving format Compare single-serve cans with larger bottles against expected lunch demand. Follow the chosen product’s instructions after opening. Individual servings may be simpler for an occasional choice; a larger bottle needs an opening and stock-rotation plan.

Common buying mistakes

  • Describing only the mixer, not the finished drink

    Tonic water served alone and tonic water served with a spirit are different lunch offers.

    Specify the complete serve on the menu, such as tonic water on its own, and do not make a spirit part of the standard workplace-lunch drink.

  • Assuming every light tonic is sugar-free

    Formulations differ. Fentimans lists 18 kcal and 3.4 g sugars per 100 ml for Naturally Light Tonic Water, while Tesco lists sweeteners in its low-calorie lemon tonic.

    Compare the nutrition panel and ingredients of the exact product. If the requirement is a plain drink with no sugar listed, check an unsweetened soda water rather than relying on “light”.

  • Choosing a non-alcoholic-style can by its name alone

    A drink presented as an alternative to a gin and tonic can raise different workplace-policy questions from soda water or tonic served alone.

    Read the current pack ABV and assess the product and its menu description against the employer’s policy before ordering.

  • Opening large bottles without a serving plan

    A bottle that is not used during lunch service still needs to be handled according to its storage instructions.

    Match bottle size to expected demand, mark when bottles are opened and follow the product label for storage and use after opening.

    Drink left in an opened bottle may need to be discarded if it cannot be used within the label’s instructions.

Brand references

These examples illustrate different mixer formulations and formats; a brand’s wider range should not be treated as having the same ingredients or nutrition values.

Fever-Tree

Its range includes light tonic and a product described by Fever-Tree as a non-alcoholic Mediterranean G&T.

  • Fever-Tree says its Refreshingly Light Premium Indian Tonic has 50% fewer calories than its own regular Premium Indian Tonic; this is a comparison with that specific product.
  • For the ready-to-drink G&T-style product, check the pack ABV and workplace policy. Check the current nutrition label of any light tonic rather than assuming it is sugar-free.

Schweppes

Schweppes offers soda water as a plain sparkling route alongside tonic options.

  • Coca-Cola Great Britain lists Schweppes Soda Water at 0 kcal and 0 g sugars.
  • Soda water does not provide tonic’s bitter flavour; compare any tonic product on its own label.

Fentimans

Naturally Light Tonic Water is a flavoured tonic option.

  • Fentimans says it has 30% fewer calories than the brand’s Premium Indian Tonic Water.
  • Fentimans lists 18 kcal and 3.4 g sugars per 100 ml for Naturally Light; it is not a zero-sugar option.

Britvic

Britvic lists a low-calorie Indian tonic among its mixer options.

  • Britvic’s product listing gives 0 g sugars for its low-calorie Indian tonic.
  • The same listing names aspartame and saccharin and includes a phenylalanine-source statement; check the exact pack when ingredient suitability matters.

Tesco

Tesco lists a 1 L low-calorie lemon Indian tonic.

  • Tesco lists 2 kcal and under 0.1 g sugars per 100 ml for this product.
  • Its ingredient list includes acesulfame K and sucralose; read the label of the product received before serving.

Sainsbury's

Sainsbury's lists a 1 L diet Indian tonic water.

  • The Sainsbury's listing gives 2 kcal per 100 ml for this product.
  • It contains acesulfame K and sucralose; check the bottle label when buying for canteen service.

Frequently asked questions

Does a mixer make a workplace lunch drink low in alcohol?

No: the finished drink matters. Serve soda water or tonic water on its own for a soft-drink option; adding a spirit makes the finished serve alcoholic. For a labelled non-alcoholic ready-to-drink product, check the pack ABV and employer policy.

What does UK guidance mean by “low alcohol”?

The Department of Health and Social Care’s UK low-alcohol descriptor guidance, published in December 2018, covers drinks of 1.2% ABV or less. That descriptor is not permission to serve a product under an employer’s alcohol policy: check the product’s pack ABV and the policy separately.

Should a canteen choose soft drinks instead of low-alcohol drinks?

That depends on the employer’s policy and the proposed serve. Soda water or tonic served without a spirit makes a straightforward soft-drink offer; assess a low-alcohol or alcohol-adjacent ready-to-drink product separately. The Health and Safety Executive says employers should manage alcohol-related workplace risks.

Are low-calorie tonic and soda water interchangeable?

No. Soda water is a plain sparkling option, while tonic has a bitter flavour and low-calorie versions may contain sweeteners. Choose according to the flavour wanted, then compare the exact products’ nutrition panels and ingredients.

How should a canteen handle opened tonic bottles?

Follow the storage and use-after-opening instructions on the bottle being served. Match bottle size to expected lunch demand, mark the opening date and rotate stock rather than assuming every tonic has the same open-life.
