Shoppers watching sugars
If you want black coffee rather than a sweetened latte, distinguish ‘no added sugar’ from the sugars shown on the nutrition panel.
Who is choosing?
Dairy-free iced-latte shoppers
A ready-to-drink oat latte may fit your preference for a dairy-free drink. Check its ingredients, allergen information and sugars for the exact product.
Decaf and caffeine-conscious shoppers
Look for an explicit decaf description or a stated caffeine amount. The words ‘cold brew’ alone do not tell you how much caffeine a serving contains.
What should you check?
Decide whether you want to mix a black coffee or open a ready-to-drink latte, then compare the label details that matter to you.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read the sugars value per 100 ml and for the portion you plan to drink. Do not treat ‘no added sugar’ as interchangeable with ‘sugar-free’. | I want to know how much sugar is in the drink, not just whether sugar was added. Sainsbury's lists 1.9 g sugars per 100 ml for Nolo's no-added-sugar oat latte. |
| Dairy and ingredients | Check the dairy-free statement and the ingredients and allergen information on the exact pack. An oat-based drink still contains oat. | A ready-to-drink dairy-free latte appeals to me, but I also need to check whether its other ingredients suit me. |
| Caffeine | Check whether the product is described as decaffeinated. For other drinks, read the caffeine amount, its stated unit and the preparation or serving instructions. | I need to account for the amount I will actually drink. Tesco Groceries lists 159 mg caffeine per 100 ml for Solo concentrate and carries a warning for caffeine-sensitive people. |
| Preparation | Check whether the coffee needs diluting and what you would add to it. Tesco Finest instructs shoppers to mix 100 ml concentrate with 100 ml cold water. | I would rather choose my own water or milk addition than buy a latte with those ingredients already mixed in. |
Common buying mistakes
-
Reading ‘no added sugar’ as ‘sugar-free’
A no-added-sugar oat latte can still contain sugars. Sainsbury's lists 1.9 g per 100 ml for Nolo and 4.8 g per 100 ml for Rodd's Original.
Compare the sugars line on the nutrition panel and the portion you intend to drink, rather than relying on the front-of-pack wording alone.
-
Assuming black cold brew is low in caffeine
Concentrate is not necessarily a low-caffeine choice: Tesco Groceries lists 159 mg caffeine per 100 ml for Solo and displays a warning for children, pregnant or nursing women and caffeine-sensitive people.
Check the caffeine amount against the concentrate quantity used to make your drink. If you want decaf, choose a product explicitly described as decaffeinated.
-
Skipping the allergen check on an oat latte
A dairy-free label does not answer every ingredient question. Nolo's dairy-free cold-brew latte contains oat.
Read the ingredients, allergen and suitability statements on the exact pack, particularly if you have a dietary restriction beyond avoiding dairy.
-
Expecting a flavoured oat latte to taste like unsweetened black coffee
These are different drinks. Marks & Spencer lists sugar among the ingredients of its Plant Kitchen oat latte, while Waitrose & Partners lists sugar in Grind Iced Vanilla Oat Latte.
If you want to add your own milk or flavouring, start with an unsweetened black coffee base and check its preparation instructions.
Brands and product lines to know
These examples illustrate different labelled formats; check the details of the particular drink rather than assuming every product from a brand is alike.
Tesco Finest
Its 500 ml unsweetened cold-brew concentrate is a black-coffee option designed to be diluted with cold water.
- Tesco Groceries describes it as 100% Arabica and suitable for vegans, with instructions to mix 100 ml concentrate with 100 ml cold water.
- Check the pack's nutrition and caffeine information if either affects your choice; ‘unsweetened’ does not specify those amounts.
Solo Coffee
Solo's black coffee concentrate suits shoppers who want to prepare their own cold coffee drink.
- Tesco Groceries lists filtered water and coffee extract as its ingredients, with sugars below 0.1 g per 100 ml.
- Tesco Groceries lists 159 mg caffeine per 100 ml and displays a warning for children, pregnant or nursing women and caffeine-sensitive people.
Nolo
Nolo's ready-to-drink cold-brew oat latte is described by Sainsbury's as water-decaffeinated, plant-based and dairy-free.
- The latte is labelled ‘no added sugar or sweeteners’.
- It contains oat, and Sainsbury's lists 1.9 g sugars per 100 ml; ‘no added sugar’ does not mean it contains no sugars.
M&S Plant Kitchen
Its 750 ml cold-brew oat latte is labelled vegan and dairy-free.
- The larger bottle offers a ready-to-drink oat-latte format.
- Marks & Spencer lists sugar among its ingredients and 2.9 g sugars per 100 g. It also carries a high-caffeine warning stating 34.6 mg per 100 ml.
Grind
Grind Iced Vanilla Oat Latte is a flavoured, ready-to-drink coffee listed by Waitrose & Partners.
- Waitrose & Partners lists cold-brew coffee as 40% of this oat drink.
- Its ingredients include sugar, and the listing gives 4.0 g sugars per 100 ml. It is not an unsweetened black coffee.
A Joybuy product option
This option is a portioned black coffee liquid to mix with water, rather than a ready-to-drink oat latte. If the cold-brew method itself matters to you, check the product's preparation description before choosing it.

J.ZAO Extra-Strong Americano Dark Roast Cold Brew Coffee Liquid, 10 × 25 ml pouches
Portioned black coffee liquid lets you add your own water or milk alternative. The product is labelled zero sugar and contains 10 pouches of 25 ml; its directions describe diluting one pouch with about 200 ml water. Check the preparation method if cold-brew processing is essential to your choice, and check the caffeine amount if you monitor your intake.
Frequently asked questions
Does ‘no added sugar’ mean a cold-brew latte is sugar-free?
No. A no-added-sugar drink can still contain sugars from its ingredients. Sainsbury's lists 1.9 g sugars per 100 ml for Nolo's oat latte and 4.8 g per 100 ml for Rodd's Original; compare the nutrition panel as well as the front label.
Which format lets me choose how much water or milk to add?
An unsweetened concentrate gives you that choice. Tesco Groceries instructs shoppers to mix 100 ml of Tesco Finest concentrate with 100 ml cold water; you can then decide whether to add milk or a milk alternative.
Is a dairy-free oat cold-brew latte suitable for every other dietary restriction?
No. For example, Nolo is labelled dairy-free but contains oat. Check the ingredients, allergen and suitability statements on the exact pack for any other restriction that matters to you.
What should I check if caffeine matters during pregnancy?
Check the caffeine amount, the quantity used to make your drink and any product warning. The NHS advises pregnant people not to exceed 200 mg caffeine a day; Tesco Groceries lists 159 mg per 100 ml for Solo concentrate and warns that it is not recommended for pregnant or nursing women. Nolo is described as decaffeinated, but check the exact product label rather than assuming every cold brew is decaf.
