Shoppers who want to control added ingredients
An unsweetened concentrate lets you choose the mixer yourself. Tesco Groceries lists 0g sugars and 12kcal for its prepared 200ml glass; milk, plant drinks or syrups will change the finished drink.
Who these options suit
Dairy-free cold-brew drinkers
Black coffee and some oat lattes offer alternatives to a milk-based drink. Check cereal allergens separately: M&S says its dairy-free Oat Latte is not suitable for people with coeliac disease or a wheat allergy.
People looking for decaf
An explicitly decaffeinated drink is a clearer starting point than an unlabelled cold brew. Sainsbury's lists Nolo Decaf Classic Cold Brew Oat Latte as decaffeinated and dairy-free; check its sugars and oat ingredients as separate considerations.
What to check before choosing
Start with the requirement that changes your choice of drink, then compare the label's serving basis and preparation directions.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Read “of which sugars” per 100ml or 100g and per serving. “No added sugar” is not the same as 0g total sugars: Sainsbury's lists 4.8g sugars per 250ml for Nolo's no-added-sugar oat latte. | I want to know the sugars in the drink I will actually serve, including anything I mix into a concentrate. |
| Serving size | Compare nutrition figures on the same stated basis. Tesco Groceries lists 0g sugars and 12kcal for a 200ml glass made with 100ml Tesco Finest concentrate and 100ml cold water. | A concentrate lets me choose the mixer, while a ready-to-drink latte has its own stated serving and ingredients. |
| Dairy and cereals | Check the exact dairy-free or vegan statement and the allergen declaration. M&S describes its Oat Latte as dairy-free but not suitable for people with coeliac disease or a wheat allergy. | I need a drink that fits my dairy requirements without overlooking an oat, wheat or coeliac restriction. |
| Caffeine | Look for an explicit decaf label or a caffeine declaration, and check the serving size. Tesco Groceries lists an average of 59mg caffeine per 100ml for Hunt and Brew Huila Colombia Coffee, whose label also carries a caution for children, pregnant or breastfeeding women, and caffeine-sensitive people. | If I am limiting caffeine, I would choose a product labelled decaffeinated rather than assume cold brew contains less caffeine. |
| Serving temperature | Follow the product's own directions. Tesco Finest specifies cold-water dilution; M&S describes its Classic Latte as ready from the fridge, and Sainsbury's says to drink Nolo chilled. | I want a genuinely hot winter drink, so I need directions that expressly allow hot preparation. |
Common buying mistakes
-
Reading “no added sugar” as sugar-free
A milk- or oat-based latte can still list sugars. Sainsbury's lists 4.8g sugars per 250ml for Nolo Decaf Classic Cold Brew Oat Latte despite its no-added-sugar wording.
Check “of which sugars” for the serving you plan to drink, then account for anything you add.
-
Assuming dairy-free covers every cereal restriction
M&S describes its Oat Latte as dairy-free but says it is not suitable for people with coeliac disease or a wheat allergy.
Read the allergen declaration for the exact drink rather than relying on its dairy-free wording.
-
Assuming cold brew is decaf
Caffeine information differs between drinks and is stated against different serving sizes. Tesco Groceries lists an average of 59mg per 100ml for Hunt and Brew Huila Colombia Coffee.
Choose an explicitly decaffeinated product when decaf matters; otherwise check the caffeine declaration against the amount you will drink.
-
Heating a drink intended to be served cold
Cold-water dilution or chilled-serving directions do not establish that a product is intended for heating.
If a hot drink is essential, choose a coffee product whose own instructions expressly permit hot preparation.

Questions about cold brew
Does “no added sugar” mean a cold brew contains no sugars?
No. Sainsbury's lists Nolo Decaf Classic Cold Brew Oat Latte as made without added sugar or sweeteners, but its nutrition information gives 4.8g sugars per 250ml. Check the total sugars line for the serving you will drink.
Which cold-brew format lists 0g sugars?
Tesco Groceries lists 0g sugars per prepared 200ml glass for Tesco Finest Unsweetened Cold Brew Coffee Concentrate, made according to its cold-water directions. Anything added to that glass changes the finished drink.
Is a dairy-free oat latte suitable for someone with coeliac disease?
Not automatically. M&S says its dairy-free Oat Latte Cold Brew Coffee is not suitable for people with coeliac disease or a wheat allergy. Check the allergen declaration on the exact product.
Can I treat cold brew as a lower-caffeine choice?
No: the name does not tell you the caffeine amount. Tesco Groceries lists an average of 59mg per 100ml for Hunt and Brew Huila Colombia Coffee. If you need decaf, look for an explicitly decaffeinated product and check its label.
Can I heat cold brew for a winter drink?
Follow the directions for the particular product. Tesco Finest specifies cold-water dilution, while the stated directions for the J.ZAO cold-brew liquid allow hot or cold water. Do not treat chilled-serving instructions for one drink as heating directions for another.
