Who is each format for?

The useful distinction for afternoon tea is whether you need a coffee base for several preferences or a finished drink for one person.

Hosts serving different preferences

An unsweetened concentrate gives you a base to dilute with water and serve black, or combine with milk or a milk alternative. Tesco Groceries gives both water and milk options in its serving instructions for Tesco Finest concentrate.

Single-serve latte drinkers

A ready-to-drink latte avoids mixing at the table. M&S lists a dairy cold-brew latte, while Waitrose & Partners lists a Grind vanilla oat latte made with cold-brew coffee; check the ingredients if milk, oats or flavouring matter to you.

Guests choosing decaf later in the day

Look for an explicit decaffeinated label rather than judging caffeine by how cold the drink is. Sainsbury's lists the Nolo cold-brew oat latte as decaffeinated and dairy-free; its oat ingredient still needs checking for anyone avoiding oats.

What should you check before buying?

Decide how you will serve the coffee, then compare the ingredients and pack instructions for that format.

PriorityWhat to checkYour needs
Sweetness and flavour Read the ingredients and sugars declaration. A plain concentrate allows additions at serving; a latte may already contain milk, sugar or flavouring. I would rather add milk or sweetness myself than serve every guest the same finished latte.
Serving format Check whether the pack needs dilution and how many drinks you intend to prepare. Tesco Groceries directs shoppers to mix 100ml of its Finest concentrate with 100ml of cold water and says the mixture can be adjusted to taste. For a table with different preferences, I want a coffee base I can mix separately. For one guest, an individual ready-to-drink latte may be simpler.
Ingredients Check the ingredient and allergen statements on the chosen pack. M&S Classic Latte contains semi-skimmed milk; the Nolo and Grind oat lattes contain oat. Someone at the table avoids dairy or oats, so the word “cold brew” alone does not tell me whether a drink suits them.
Caffeine Look for a decaffeinated label when that is the requirement, and check any caffeine quantity declared on the pack. Do not use serving temperature to judge caffeine content. For a later-afternoon gathering, I want guests to be able to choose a labelled decaf drink.
Storage Check chilling and opened-pack instructions before choosing a larger pack. Tesco Finest concentrate’s instructions say to refrigerate it after opening and use it within four weeks. If concentrate is left after the gathering, I need to know whether I can store and use it as directed.

Common buying mistakes

  • Assuming every cold coffee is plain black coffee

    Cold-coffee choices include concentrates, dairy lattes and flavoured oat drinks. M&S Classic Latte contains milk, while Tesco Finest concentrate is intended to be mixed before serving.

    Choose the format first, then read the ingredients and nutrition panel for the particular drink.

  • Judging caffeine by the drink’s temperature

    A cold coffee is not necessarily decaffeinated. For guests monitoring intake, the relevant details are the product’s caffeine declaration, where given, and whether it is labelled decaf.

    Offer an explicitly labelled decaf choice when needed. NHS guidance says caffeine intake during pregnancy should not exceed 200mg a day.

  • Buying concentrate as though it were ready to drink

    Tesco Groceries instructs shoppers to dilute its Finest concentrate, so serving it involves preparing each glass rather than opening an individual drink.

    Plan the water, ice and any milk you want to offer, and follow the opened-pack storage instructions.

    A larger opened pack also needs space in the fridge and a plan for using what remains within the stated period.

  • Confusing coffee liqueur with a non-alcoholic drink

    A cold-brew coffee liqueur is an alcoholic product category, not a substitute for ordinary cold-brew coffee at a table where a non-alcoholic drink is intended.

    Check the full product name and alcohol information before buying, particularly when serving children or guests avoiding alcohol.

Brands and retailer options

These listings illustrate different drink formats; a retailer’s wider iced-coffee range should not be treated as a range of cold brews.

Tesco Finest

Tesco Groceries lists an unsweetened 500ml cold-brew concentrate that can be prepared with water or combined with milk or a milk alternative.

  • Its serving instructions allow the dilution to be adjusted for different glasses.
  • It needs mixing; refrigerate the bottle after opening and follow its four-week use instruction.

M&S

M&S Classic Latte Cold Brew is a 250ml ready-to-drink coffee made with semi-skimmed milk.

  • The individual drink needs no dilution before serving.
  • Its milk and sugar ingredients make it a different choice from an unsweetened, dairy-free coffee base.

Sainsbury's

Sainsbury's lists Nolo Decaf Classic Cold Brew Oat Latte, a 250ml decaffeinated, dairy-free drink.

  • The Nolo listing states that it has no added sugar or sweeteners.
  • It contains oat and is an individual flavoured latte, not a plain coffee concentrate.

Waitrose

Waitrose & Partners lists Grind Iced Vanilla Oat Latte, which combines cold-brew coffee with an oat drink and vanilla flavour.

  • It provides an oat-based, ready-to-drink latte format.
  • It contains oats and is a flavoured latte rather than a plain black cold brew.

Sandows

Coffee Friend UK describes Sandows as a ready-to-drink black cold brew made with coffee and filtered water.

  • The retailer listing describes it as free from dairy and sugar.
  • Check the particular pack’s caffeine declaration if you are choosing for a guest who monitors caffeine.

Questions about serving cold brew

Should I buy concentrate or a ready-to-drink coffee for afternoon tea?

Choose concentrate when you want to prepare different drinks from one base; choose a ready-to-drink coffee when individual servings without mixing matter more. Tesco Groceries suggests equal quantities of its Finest concentrate and cold water as a starting point, with milk or a milk alternative also possible.

How do I choose a dairy-free cold brew?

Read the ingredients and allergen statement on the exact product. Tesco Finest concentrate is labelled suitable for vegans, and Sainsbury's lists Nolo oat latte as dairy-free; Nolo contains oat, while M&S Classic Latte contains semi-skimmed milk.

What if a guest wants to avoid caffeine later in the day?

Choose a drink explicitly labelled decaffeinated, such as the Nolo cold-brew oat latte listed by Sainsbury's, rather than assuming all cold brew is low in caffeine. Check the pack for any caffeine declaration relevant to the guest’s total intake; NHS guidance limits caffeine during pregnancy to 200mg a day.

How should I keep cold brew after opening?

Follow the instructions on the individual pack because storage depends on the product. Tesco Finest concentrate says to refrigerate it after opening and use it within four weeks; check a ready-to-drink product’s own instructions rather than applying that period to it.

Is cold-brew coffee liqueur a substitute for cold-brew coffee?

No, a coffee liqueur is an alcoholic product, not an ordinary non-alcoholic cold-brew drink. Check the product name and alcohol information when choosing drinks for guests.
