Who is each option for?

Students with fridge space

A multi-serve concentrate can work if you have room for an opened bottle and will use it regularly. Tesco Groceries instructs buyers to refrigerate its listed Nescafé and Starbucks concentrates after opening and consume them within 14 days.

Students who want coffee fizz

Look for instructions that name tonic or another sparkling mixer. Tesco Groceries gives tonic-water directions for the Nescafé and Starbucks concentrates; neither is presented as a pre-carbonated drink.

Students checking ingredients and drink type

Check the exact product if sugar, dairy or alcohol matters to your choice. Coffee Friend UK describes its Sandows cold brew as sugar-free and dairy-free, while Sainsbury's identifies Tia Maria Cold Brew Coffee Liqueur as an alcoholic product.

What should you check before buying?

Decide whether you want to mix a fizzy drink or open a bottle, then check the preparation instructions and storage conditions for the exact product.

Concentrate with a sparkling mixer

Choose it when: You want coffee fizz and are happy to add tonic or sparkling water yourself; Tesco Groceries explicitly suggests tonic for its listed Nescafé and Starbucks concentrates.

Allow for: The mixer and preparation are separate, and those two Tesco-listed bottles need refrigeration after opening.

Ready-to-drink cold brew

Choose it when: Opening a single bottle matters more than fizz; Coffee Friend UK describes its Sandows cold brew as ready to drink.

Allow for: A cold-brew label does not establish carbonation, so check for an explicit sparkling claim if fizz is essential.

PriorityWhat to checkYour needs
PreparationRead the mixing directions. Check what drink, glass and ice you will need.I want to make a cold coffee in a shared kitchen without a coffee machine.
FizzLook for an explicit carbonation claim on a ready-made drink, or directions naming a sparkling mixer. Tesco Groceries names tonic for its listed Nescafé and Starbucks concentrates.If fizz is the point, a chilled coffee without a carbonation claim will not answer my buying question.
Storage and servingsCheck serving yield against likely use. Tesco Groceries lists 16 servings for its 500 ml Nescafé concentrate and eight glasses for its 260 ml Starbucks concentrate; both say to refrigerate after opening and consume within 14 days.Will I have fridge space and finish an opened bottle during the move-in period?
IngredientsRead the ingredients and the basis for any nutrition figures. Values for a drink prepared with milk cannot be applied unchanged to one made with tonic.I may prefer an unsweetened coffee mix, or need to check what a flavoured option and my chosen mixer contain.
Drink typeCheck whether the label describes coffee, a coffee concentrate or a liqueur. Sainsbury's lists Tia Maria Cold Brew Coffee Liqueur as an alcoholic product.For an everyday cold coffee, I do not want to mistake a cocktail ingredient for a soft drink.

What is easy to overlook?

  • Assuming cold brew means sparkling

    Coffee Friend UK describes its Sandows bottle as ready-to-drink cold brew but does not identify it as carbonated. By contrast, the Tesco-listed sparkling-style preparations involve adding tonic to a concentrate.

    For a fizzy drink, check for an explicit carbonation statement or mixing instructions that name a sparkling drink.

  • Opening more concentrate than you will use

    Tesco Groceries says its listed Nescafé and Starbucks concentrates must be refrigerated and consumed within 14 days of opening.

    Compare the stated serving yield with how often you expect to make a drink, and check that you can store the bottle as directed.

    An unfinished bottle may mean discarded coffee.

  • Comparing drinks made with different mixers

    Nutrition figures based on preparation with milk do not describe the same drink made with tonic.

    Check the concentrate label and the particular mixer you plan to use, including the amounts in your glass.

  • Mistaking coffee liqueur for cold coffee

    Sainsbury's describes Tia Maria Cold Brew Coffee Liqueur as an alcoholic cocktail ingredient, not a non-alcoholic ready-to-drink coffee.

    Check the product category and pack label. Sainsbury's displays conflicting alcohol figures for this listing, so do not rely on a single displayed figure.

Which brand references are useful?

These retailer and product examples help distinguish concentrates, ready-to-drink coffee and liqueur; a brand name alone does not tell you whether a drink is sparkling.

Tesco

Tesco Groceries lists iced-coffee concentrates, including products with instructions for mixing with tonic.

  • Its listed Nescafé and Starbucks concentrates give tonic-water preparation options.
  • Those concentrates are not themselves described as pre-carbonated and must be refrigerated after opening.

M&S

Marks & Spencer lists an Oat Latte Cold Brew Coffee 250 ml among its chilled drinks.

  • The listing provides a ready-to-drink cold-brew option to consider.
  • Sparkling drinks appear separately in the catalogue; the oat latte is not identified there as sparkling.

Waitrose

Waitrose & Partners lists Nescafé Espresso Concentrated Iced Classic, Vanilla and Caramel products.

  • The range offers several named concentrate flavours.
  • Check the instructions on the exact variant before planning to use a sparkling mixer.

Sandows

Coffee Friend UK describes Sandows as a 200 ml ready-to-drink cold brew made from coffee and filtered water.

  • That listing describes the product as sugar-free and dairy-free.
  • The description does not establish that the drink is carbonated.

Sainsbury's

Sainsbury's lists Tia Maria Cold Brew Coffee Liqueur as an alcoholic coffee product.

  • The liqueur description makes its cocktail use clear.
  • It is not a substitute for non-alcoholic cold brew, and the listing's alcohol figures conflict.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 10 × 25 ml pouches

For a sparkling coffee-style drink, the product directions allow mixing a pouch with sparkling water; the concentrate is not pre-carbonated, so you will need to supply the water and a cup.

Frequently asked questions

Can I make a sparkling coffee without a coffee machine?

Yes, with a concentrate whose directions allow a sparkling mixer. Tesco Groceries says its listed Nescafé concentrate can be mixed with tonic water and suggests tonic for its Starbucks concentrate; you add the mixer yourself rather than opening a pre-carbonated coffee.

How should I store an opened coffee concentrate?

For the Nescafé and Starbucks concentrates described by Tesco Groceries, refrigerate after opening and consume within 14 days. Follow the instructions on the exact product you buy, as they can differ.

Does cold brew mean sugar-free or dairy-free?

No; check the specific drink and anything you add to it. Coffee Friend UK describes its Sandows cold brew as sugar-free and dairy-free, while Tesco Groceries lists sugar in its Starbucks caramel concentrate. A milk-based prepared serving also differs from one you mix with tonic.

Is every product labelled cold brew coffee non-alcoholic?

No. Sainsbury's describes Tia Maria Cold Brew Coffee Liqueur as an alcoholic product for cocktails. If you want an everyday cold coffee, check the drink category and pack label rather than relying on the words “cold brew”.
