Who is each format for?

Cream tea hosts

If jam and clotted cream already provide the sweet part of the spread, black cold brew keeps the coffee itself unsweetened. A concentrate lets you dilute individual servings and offer additions separately.

No-added-sugar latte drinkers

A ready-to-drink oat or milk latte offers a creamy alternative to black coffee. Check both the no-added-sugar claim and the nutrition panel: Sainsbury's lists 4.8 g sugars per 100 ml for Rodd's Original oat cold-brew latte.

Guests avoiding dairy

Look for a clearly labelled dairy-free black coffee or oat drink, then check the allergen statement on the pack. A cold-brew label alone does not tell you whether the drink contains milk.

What should you check before buying?

For a cream tea, decide how you want to serve the coffee, then check the finished drink rather than relying on a claim on the front of the pack.

Priority What to check Your needs
Sweetness Compare the no-added-sugar or unsweetened wording with the ingredients and the ‘of which sugars’ figure. Check any milk, plant drink or flavouring you add. I want the coffee to sit alongside jam and cream without making the drink sweet too. A no-added-sugar label does not tell me how much naturally occurring sugar remains.
Serving format Black ready-to-drink coffee can be poured as supplied; a concentrate needs dilution. Follow the pack directions and offer optional additions separately. For several guests, I would like to prepare individual drinks. If everyone wants coffee ready to pour, I would choose that format instead.
Dairy suitability Check whether the base is coffee and water, an oat drink or milk. Read the exact product's ingredient and allergen statements. Some guests avoid dairy, so I need a clearly labelled option for them rather than assuming every cold brew is suitable.
Caffeine Look for caffeine information per bottle or prepared serving, and account for tea and other caffeinated drinks served that day. I want guests who limit caffeine to know what is being served. Food Standards Agency guidance on caffeine-containing food supplements considers intake across all sources, not just one coffee.

Common buying mistakes

  • Reading ‘no added sugar’ as ‘sugar-free’

    Milk- and oat-based drinks can contain sugars even when labelled no added sugar. Sainsbury's lists 4.8 g sugars per 100 ml for Rodd's Original oat latte.

    Check the ingredients and the ‘of which sugars’ line for the exact drink you plan to serve.

  • Assuming every cold brew is dairy-free

    Cold brew describes how the coffee is prepared, not whether the finished drink contains milk. Tesco describes Hunt and Brew Huila Colombia as cold-brew coffee with whole milk.

    For guests avoiding dairy, choose a clearly labelled black or dairy-free oat option and read its allergen statement.

  • Choosing a flavoured drink when you want plain coffee

    A no-added-sugar drink can still contain flavouring or sweetener. Tesco lists sweetener in Starbucks Caramel No Added Sugar, so it offers a different flavour from an unsweetened black cold brew.

    Check the ingredients if you want coffee without a caramel or other flavoured note alongside cream tea.

  • Overlooking caffeine when offering refills

    Coffee served with tea adds another possible source of caffeine during the gathering.

    Check caffeine information where available, make serving sizes clear and consider offering a decaffeinated drink as another choice.

Brands and retailer examples

These examples show how different cold-coffee formats are described; the claim and ingredients need checking on the particular product you choose.

Tesco

Tesco lists both an unsweetened cold-brew concentrate under its Finest range and Hunt and Brew's no-added-sugar milk cold brew.

  • Tesco Finest Unsweetened Cold Brew Coffee Concentrate is described as made with 100% Arabica coffee and can be diluted for individual servings.
  • Hunt and Brew Huila Colombia contains whole milk, so it does not suit guests avoiding dairy.

Sainsbury's

Sainsbury's lists oat-based cold-brew lattes, including Rodd's Original and a decaffeinated Nolo option.

  • Rodd's Original is described as dairy-free and no added sugar; Nolo's decaf oat latte is described as having no added sugar or sweeteners.
  • No added sugar does not make an oat latte sugar-free: Sainsbury's lists 4.8 g sugars per 100 ml for Rodd's Original.

Sandows

Sandows makes cold brew in London. Coffee Friend UK describes its ready-to-drink black coffee as made with fresh coffee and filtered water.

  • Coffee Friend UK lists the black cold brew as dairy-free, with 0 g sugars per 100 ml.
  • A black coffee will not provide the milk-based texture some guests want from a latte.

M&S

M&S describes its Plant Kitchen Chilled Cold Brew Oat Latte as dairy-free and made with British oats and Colombian coffee.

  • The oat base provides a dairy-free latte-style format.
  • Check the current pack for a no-added-sugar claim and its sugars declaration before choosing it for that preference.

Waitrose

Waitrose lists Mockingbird Raw Coffee Smoothie as a coffee-containing drink with a no-added-sugar statement.

  • Its listing identifies the drink as a smoothie made with fruit juices and purées, oats, honey and coffee, making its format clear.
  • It is a smoothie-style drink, not a substitute for plain black cold brew if that is what you want alongside cream tea.

A Joybuy concentrate option

This option is for preparing individual black cold-coffee servings with water. Dilution gives you control over the serve, but it does not offer the ready-to-drink oat or milk latte format discussed above.

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

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

The individual pouches allow you to prepare black cold-coffee servings for guests. The product information lists water and Arabica coffee as ingredients and 0 g sugars per 100 ml. Directions suggest diluting one 25 ml pouch with about 200 ml cold water, adjusting to taste. Check the pack's caffeine information if a guest limits caffeine.

Frequently asked questions

Does ‘no added sugar’ mean a cold brew is sugar-free?

No. A drink labelled no added sugar can still contain naturally occurring sugars. For example, Sainsbury's lists 4.8 g sugars per 100 ml for Rodd's Original oat cold-brew latte, so compare the nutrition panel as well as the front-of-pack claim.

How can I serve cold brew to several people at a cream tea?

A concentrate lets you prepare individual iced servings and offer milk or a plant drink separately. Tesco describes its Finest cold brew concentrate as unsweetened; follow the dilution directions on the pack you buy.

What can I offer guests who avoid dairy?

Choose a cold coffee explicitly labelled dairy-free and check its current allergen statement. Coffee Friend UK describes Sandows black cold brew as dairy-free, while Sainsbury's describes Rodd's Original as an oat-based, dairy-free latte; Tesco's Hunt and Brew Huila Colombia contains whole milk.

Should I consider caffeine when serving cold brew in the afternoon?

Yes. Caffeine from cold brew adds to caffeine from tea and other drinks. Food Standards Agency guidance on caffeine-containing food supplements considers total daily intake from all sources, so check serving information where available and offer a decaffeinated choice if useful.

Is a coffee smoothie the same choice as black cold brew?

No. Waitrose describes Mockingbird Raw Coffee Smoothie as a blend containing fruit juices and purées, oats, honey and coffee. Choose it if you want that smoothie-style drink, rather than the coffee-and-water format of black cold brew.
