Students and commuters comparing sugars
A portable black coffee, oat latte and flavoured milk coffee can have different sugar totals. Check the whole can or prepared serving, particularly if zero sugar is the requirement.
Who needs to check the label?
The useful distinction is not simply whether a drink says “cold brew”, but what is in the portion you will drink and who will drink it.
People choosing around caffeine
Look for a specifically decaffeinated drink when avoiding caffeine is the priority. For other drinks, check the amount for the full container and any warning on that product.
Plant-based and allergy-aware shoppers
Black coffee, oat drinks and dairy lattes have different ingredients. Check the declaration on the exact pack rather than assuming that “plant-based” covers every allergen concern.
What matters when choosing cold brew?
Choose the format around your main constraint, then compare the portion, ingredients and pack instructions of individual drinks.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and energy | Read sugars and energy for the prepared serving or whole can. Check added ingredients as well as the nutrition panel: “no added sugar” is not the same as 0g sugars. | I want to know what is in the drink I will actually have. Tesco Groceries lists 0g sugars and 12kcal for a 200ml serving of Finest concentrate prepared with water; Sainsbury’s lists 4.8g sugars in a 250ml can of Nolo’s no-added-sugar oat latte. |
| Caffeine | Look for decaffeination, caffeine per 100ml or per container, and product-specific warnings. Account for the whole bottle rather than comparing per-100ml figures alone. | If I am choosing a drink for later in the day or for someone who needs to avoid caffeine, a specifically decaffeinated option is the clearer starting point. Sainsbury’s describes Nolo’s oat latte as water-decaffeinated. |
| Ingredients and allergens | Check the exact pack for milk, oat and other declared allergens. A dairy-free claim does not establish suitability for every other allergy. | I need a drink that fits my ingredient requirements, not just a plant-based name. Tesco lists its Finest black concentrate as suitable for vegans, while Sainsbury’s identifies Nolo as an oat drink. |
| Preparation and storage | Check whether the product is a concentrate or ready to drink, what is added when serving it, and the pack’s chilled-storage and after-opening instructions. | For a school or work routine, I need to know whether I can take one drink or must prepare it first. Added milk, plant drink or syrup changes the finished drink from the concentrate’s water-prepared nutrition. |
Common cold-brew mix-ups
-
Assuming “cold brew” means zero sugar
Cold brew describes how the coffee is made, not the finished drink’s ingredients. Marks & Spencer lists sugar in its Caramel Latte Cold Brew and 3.6g sugars per 100g.
Compare the sugars line for the portion you intend to drink. If you require 0g sugars, check for that figure on the chosen product’s nutrition panel.
-
Reading “no added sugar” as “no sugars”
Sainsbury’s lists 4.8g sugars in Nolo’s 250ml no-added-sugar oat latte. Its ingredients can contribute sugars even though the product carries a no-added-sugar claim.
Use the ingredients list to understand the claim and the nutrition panel to check total sugars.
-
Overlooking caffeine in a cold or milky drink
Marks & Spencer lists 34.6mg caffeine per 100ml for its Plant Kitchen Cold Brew Oat Latte and says it is not recommended for children, pregnant or breastfeeding women. A milky format does not remove the need to read the warning.
Check the chosen pack’s caffeine amount and warnings, especially when the drink is for someone who needs to avoid caffeine.
-
Forgetting how the pack will be stored
A concentrate used across several drinks and a single ready-to-drink can call for different preparation and after-opening plans.
Check the pack’s refrigeration and after-opening instructions, and choose a size you can use within those instructions.
Brand and retailer examples
These examples show why the exact drink matters more than a retailer or brand name; they do not describe every product in each range.
Tesco Finest
Tesco Groceries lists an unsweetened cold-brew concentrate that is prepared with water rather than sold as a finished latte.
- The listed 200ml water-prepared serving contains 0g sugars and 12kcal.
- Adding milk or other ingredients changes the finished drink; check the pack for caffeine information if it affects your choice.
M&S
Marks & Spencer lists both a Caramel Latte Cold Brew and a Plant Kitchen Cold Brew Oat Latte.
- The Plant Kitchen oat latte is listed as vegan and carries a stated caffeine amount of 34.6mg per 100ml.
- The caramel latte contains sugar and lists 3.6g sugars per 100g. The Plant Kitchen drink carries a warning that it is not recommended for children, pregnant or breastfeeding women.
Sainsbury’s
Sainsbury’s lists Nolo’s decaffeinated oat cold-brew latte alongside Rodd’s no-added-sugar oat latte.
- Nolo is described as water-decaffeinated and dairy-free, with no added sugar or sweeteners.
- Nolo still lists 4.8g sugars per 250ml. Rodd’s lists 4.8g sugars per 100ml, so compare portions rather than relying on the shared no-added-sugar wording.
Waitrose
Waitrose lists Emmi Caffè Latte Cappuccino as a ready-to-drink iced coffee; its listing does not establish that it is cold brewed.
- Its listing gives ingredients, sugars and caffeine information for comparing this iced-coffee format.
- It contains milk and sugar, and Waitrose lists 9.3g sugars per 100ml and 87mg caffeine per cup. It is not evidence that Waitrose’s cold-brew options share those figures.
Sandows
Coffee Friend UK lists a ready-to-drink Sandows black cold brew, providing a comparison with latte-style drinks.
- That retailer lists 0g sugars and 6kcal per 100ml.
- The same retailer lists 40.5mg caffeine per 100ml; check the current pack before choosing it around caffeine.
A Joybuy cold-brew option
This pouch-format black coffee option is relevant if you would rather prepare individual portions than take a ready-to-drink latte. Check its current label for the finished drink’s nutrition and caffeine.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, Dark Roast, 10 × 25ml pouches
The 10 × 25ml pouch format is worth considering if you want to prepare individual portions for a school or work routine. The product name describes it as zero sugar; check the current pack’s nutrition, dilution directions and caffeine information before deciding how it fits your needs.
Cold-brew questions
Does “no added sugar” mean a cold brew has 0g sugars?
No. Sainsbury’s lists Nolo’s oat latte as having no added sugar or sweeteners, but its 250ml can contains 4.8g sugars. Check total sugars on the nutrition panel if zero sugar is your requirement.
Which cold brew should I check if I want to avoid caffeine?
Start with a product specifically described as decaffeinated rather than assuming cold brew contains less caffeine. Sainsbury’s describes Nolo’s Classic Cold Brew Oat Latte as water-decaffeinated; check the current label of the drink you choose.
How does caffeine affect the choice during pregnancy?
The NHS advises no more than 200mg caffeine a day during pregnancy, so the amount in the whole drink matters alongside caffeine from other sources. Check the product’s own warning and caffeine information: Marks & Spencer lists 34.6mg per 100ml for its Plant Kitchen Cold Brew Oat Latte and says it is not recommended for pregnant women.
Is a plant-based cold brew suitable for every allergy concern?
No. A dairy-free description does not establish that a drink is free from other relevant allergens. Nolo’s cold-brew latte contains oat, so check the ingredient and allergen declaration on the exact pack.
