What should you check?
Start with the sugars and ingredients, then check whether the caffeine and storage instructions fit the journey.
| Priority | What to check | Your needs |
| Sugars |
Read the ingredients and “of which sugars” value per 100ml. Use the container size to work out the amount in a full drink; “no added sugar” does not mean 0g sugars. |
I want to distinguish a drink with no sugar added from one with 0g sugars listed. Tesco lists 3.1g sugars per 100ml for the no-added-sugar Hunt and Brew Huila Colombia; Coffee Friend lists 0g per 100ml for Sandows. |
| Caffeine |
Check mg per 100ml and the container volume, plus any on-pack suitability warning. Count caffeine from other food and drinks when a daily limit applies. |
A small-looking bottle could still contain more caffeine than I expect. Tesco’s 59mg per 100ml figure for Hunt and Brew Huila Colombia works out to about 195mg per 330ml bottle. NHS guidance sets a 200mg daily limit during pregnancy from all sources. |
| Storage |
Look for cool, dry storage or a keep-refrigerated instruction. For chilled drinks, follow the stated temperature and directions after opening. |
If I cannot rely on a fridge during a day trip, I need an unopened drink whose label permits storage in a cool, dry place. M&S gives that instruction for its Oat Latte Cold Brew, while Tesco says to keep Hunt and Brew Huila Colombia refrigerated. |
| Ingredients and allergens |
Check for milk and read the exact pack’s allergen statement. An oat-based drink is not automatically suitable for someone avoiding wheat or gluten. |
I may want to avoid dairy without overlooking another ingredient that matters to me. M&S says its Oat Latte Cold Brew is not suitable for coeliacs or people with a wheat allergy. |
Joybuy coffee options
These are black coffees you prepare with cold water for a trip: one cold-brew concentrate and one instant powder. Neither is a ready-to-drink bottle, and dissolving instant coffee in cold water does not establish that it was cold-brewed.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 25ml × 10 pouches
Individual pouches can be mixed with cold water while travelling; this is a concentrate, not a ready-to-drink coffee. The listed ingredients are water and Arabica coffee, and the concentrate’s nutrition table gives 0g sugars per 100ml. Store in a cool, dry place and check the pack’s caffeine information if that affects your choice.

J.ZAO Freeze-Dried Instant Black Coffee Powder, 2g × 24 capsules
The 2g portions dissolve in cold water and are listed for cool, dry storage, but this is instant coffee rather than confirmed cold-brew coffee. The listed ingredient is Arabica coffee; the nutrition figure of 2.1g sugars per 100g refers to the dry powder, not a prepared cup. Check the exact flavour variant, ingredients and caffeine information on the pack.

Questions about choosing cold brew
Does “no added sugar” mean a cold brew contains no sugar?
No. A milk coffee can contain naturally occurring sugars without sugar being added. Tesco lists 3.1g sugars per 100ml for Hunt and Brew Huila Colombia. Check the “of which sugars” value if the total in your drink matters to you.
Which black cold brew has 0g listed sugars?
Coffee Friend’s listing for Sandows Cold Brew Coffee reports 0g sugars per 100ml and names coffee and filtered water as its ingredients. Check the current pack before buying, particularly if you also need its caffeine or storage instructions.
What should I check about caffeine during pregnancy?
Check the caffeine in the entire drink alongside caffeine from other sources. NHS guidance says pregnant people should not have more than 200mg a day; Tesco’s listed 59mg per 100ml for Hunt and Brew Huila Colombia works out to about 195mg per 330ml bottle. Follow any suitability warning on the pack.
Can I pack a cold brew without a cool bag?
Only if its storage instructions suit the conditions of your trip. M&S says its Oat Latte Cold Brew can be stored in a cool, dry place, while Tesco says Hunt and Brew Huila Colombia must be refrigerated. Follow the individual pack’s instructions, including those for use after opening.
Is an oat cold brew automatically suitable for someone with coeliac disease?
No. Dairy-free and suitability for coeliacs are separate checks. M&S says its Oat Latte Cold Brew is not suitable for coeliacs or people with a wheat allergy, so read the allergen statement on the exact product.
