Who might choose each format

Students who need a drink ready for lunch

An individually portioned, ready-to-drink can avoids measuring cordial or finding water between lectures.

Students with water and a reusable bottle

Bottled cordial is an option if you can dilute it before leaving or have water available when you want a drink.

Students checking ingredients and nutrition

Compare the exact flavour and serving you intend to drink, particularly if sugar, sweeteners or an ingredient you avoid affects your choice.

What to check before buying

Decide first whether you can prepare a drink, then compare pack portions and the labels for the drink you would actually consume.

Priority What to check Your needs
Ready to drink Check whether the product is ready to drink or a concentrate. Confirm its individual portion and whether you need water or a separate bottle. I want to open my lunch drink between lectures without mixing it.
Dilution For cordial, follow the ratio on the exact bottle. Sainsbury’s lists one part Robinsons Crushed Lime & Mint concentrate to six parts water. A refillable bottle works for me if I can reliably get water and prepare the drink.
Sugar and sweeteners Compare nutrition for the prepared cordial serving with the amount you would drink from a can. Read the ingredients as well as claims such as ‘no added sugar’. I want to know what is in my finished drink, not just what the front of the pack says.
Ingredients Check the current pack for the precise flavour and size, including any relevant allergen information; do not rely solely on a retailer listing. When an ingredient matters to me, I need to check the pack I am buying.
Pack size Compare the number and volume of individual drinks with your available storage and how many lunches you expect the pack to cover. I have room for the remaining drinks and a use for them after this lunch.

Common buying mistakes

  • Picking cordial when you need a drink to open immediately

    The Robinsons cordial listed by Sainsbury’s is a concentrate with a one-to-six dilution instruction, not a ready-to-drink can.

    Choose a ready-to-drink product if you cannot bring water and a drinking bottle; otherwise, plan when you will dilute the cordial.

  • Comparing concentrate with a finished can

    A cordial label may describe nutrition for the diluted drink. Making it at a different strength changes the amount of concentrate in your serving.

    Use the bottle’s dilution instructions and compare the resulting serving with the amount you would drink from a can.

  • Reading ‘no added sugar’ as an ingredient list

    Waitrose lists a Belvoir no-added-sugar cordial that contains sweeteners. The claim alone does not tell you whether a particular ingredient suits your needs.

    Read the current ingredients and nutrition panel for the exact flavour and pack.

  • Choosing a multipack by can count alone

    Counts and can volumes vary, so a larger pack also means more individual drinks to store and use.

    Check both the can volume and pack count against the lunches you are planning for.

Brand and retailer references

Robinsons

The Crushed Lime & Mint Fruit Cordial listed by Sainsbury’s is a bottled concentrate for a drink you prepare with water.

  • The 500ml bottle specifies one part concentrate to six parts water.
  • It is not a ready-to-drink can. Check the current ingredients if you need to avoid particular sweeteners or sulphite-containing ingredients.

Tesco

Tesco’s fizzy-drink-can category provides ready-to-drink multipack examples rather than a list of cordials.

  • Its listing includes six- and 18-can packs of 330ml drinks.
  • Check each product’s own label; a category listing does not establish its ingredients or whether it suits a particular need.

Waitrose

Waitrose lists bottled cordials, including standard and no-added-sugar products.

  • Its cordial listings give bottled options to compare if you can prepare a drink with water.
  • The Belvoir no-added-sugar cordial listed by Waitrose still requires dilution and contains sweeteners.

Questions about lunch drinks

Can I take cordial for a university lecture lunch?

Yes, if you can prepare it with water before drinking. Sainsbury’s lists Robinsons Crushed Lime & Mint as a concentrate diluted one part to six parts water, so you will also need a suitable drinking container.

Is a multipack of cans the same thing as cordial?

Not necessarily. Tesco lists multipack cans under fizzy drinks, while the cordial examples listed by Sainsbury’s and Waitrose are bottled concentrates. Check the exact product label rather than treating the formats as interchangeable.

Does no-added-sugar cordial contain no sugar or sweeteners?

No: the Belvoir no-added-sugar cordial listed by Waitrose contains sweeteners and has a stated sugar value for the diluted drink. Read the ingredients and nutrition panel for the exact product you intend to buy.

What if I need to avoid a particular ingredient?

Check the current pack’s ingredient list and any allergen information before drinking it. The Robinsons cordial listed by Sainsbury’s includes sodium metabisulphite, so the precise product and flavour matter.

How can I compare sugar in a can and a cordial?

Compare the amount you would actually drink: use the stated diluted serving for cordial and the relevant per-can or per-100ml information for a canned drink. Follow the cordial’s dilution instructions, because a stronger mixture uses more concentrate per serving.
