Shoppers watching total sugar
If you want coffee rather than breakfast, compare sugars in the whole drink you will have. An unsweetened black coffee and a no-added-sugar oat latte need not have the same sugar content.
Who is choosing cold brew?
The useful distinction is not simply black coffee versus latte: sugar, caffeine and ingredients can change which drink fits your morning break.
Shoppers checking caffeine
If you are avoiding caffeine, look for a drink labelled decaffeinated. If you are tracking intake, use the caffeine amount for the portion you will drink rather than assuming cold brew is mild.
Plant-based latte drinkers
If you prefer a dairy-free latte to black coffee, check its sugars, caffeine and allergen statement as well as the dairy-free description. Oat-based drinks can contain ingredients you need to avoid.
What should you check before choosing?
Decide whether the drink is a light break or a substitute for a missed meal, then compare the portion you will actually consume. For a concentrate, include anything you add after dilution.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugar | Read sugars per prepared serving or whole pack, not just the “no added sugar” claim. Tesco Groceries lists 0g sugars per 200ml glass of its concentrate diluted with water; Sainsbury’s lists 4.8g per 250ml can of Nolo’s no-added-sugar oat latte. | I want to know how much sugar is in my finished drink, including any milk or flavouring I add. |
| Caffeine | Compare the amount per bottle or per 100ml with the quantity you will drink. Sainsbury’s lists 41mg per 250ml bottle for Rodd’s Original Latte; Marks & Spencer lists 34.6mg per 100ml for its Plant Kitchen latte. Choose a labelled decaf product if avoidance is the priority. | Cold brew needs to fit alongside the other caffeinated drinks I have that day. During pregnancy, the NHS advises no more than 200mg of caffeine a day in total. |
| Ingredients and allergens | Check the exact pack’s ingredients and allergen statement. Nolo contains oat, while Marks & Spencer says its Plant Kitchen oat latte is not suitable for coeliacs or people with soya or wheat allergy. | I may want a dairy-free latte, but I still need to check whether its other ingredients suit me. |
| Drink or meal | Compare energy for the full portion and consider what the drink is replacing. Tesco Groceries lists 12 kcal per prepared 200ml glass of its unsweetened concentrate; its listing for the 500ml yfood meal-style drink gives 500 kcal per pack. | For a short coffee break, I am choosing a drink. If I have missed breakfast, I am making a different choice about a meal-style product. |
| Preparation and storage | Check whether the coffee needs diluting and follow its serving directions. For a chilled bottle, check the opening instructions: Sainsbury’s says to keep Rodd’s Original Latte chilled and consume it within three days of opening. | At home I can mix a concentrate; away from home, I might prefer a ready-to-drink bottle whose storage instructions I can follow. |
Common cold-brew buying mistakes
-
Reading “no added sugar” as “zero sugar”
A latte can contain sugars even when none is added as an ingredient. Sainsbury’s lists 4.8g sugars per 100ml for Rodd’s Original Latte despite its no-added-sugar description.
If your aim is zero sugar, check the sugars figure for the drink as consumed, including anything you add.
-
Checking caffeine without checking portion size
Marks & Spencer lists 34.6mg caffeine per 100ml for its Plant Kitchen latte and warns that it is not recommended for children or for pregnant or breastfeeding women. The NHS advises a total limit of 200mg caffeine a day during pregnancy.
Work out how much of the drink you plan to have and account for other caffeine that day. If avoidance is the requirement, look for a product labelled decaffeinated.
-
Choosing a meal-style drink for a light break
Tesco Groceries lists 500 kcal in the full 500ml yfood Cold Brew Coffee pack. Its unsweetened concentrate, prepared as directed with water, lists 12 kcal per 200ml glass; these are drinks intended for different roles.
Decide whether you want coffee during a break or a product to stand in for a missed meal before comparing the packs.
-
Assuming dairy-free means free from other allergens
Nolo’s oat latte contains oat. Marks & Spencer states that its Plant Kitchen oat latte is not suitable for coeliacs or people with soya or wheat allergy.
Check the ingredient and allergen information on the exact pack you are buying, even if its front label says dairy-free.

For a break where you can prepare a black coffee, the directions describe adding about 200ml of cold or hot water to one 25ml pouch. The product name states zero sugar.

Cold-brew questions answered
Does “no added sugar” mean a cold-brew latte has no sugar?
No. Check the total sugars figure as well as the claim: Sainsbury’s lists 4.8g sugars per 250ml can for Nolo’s no-added-sugar oat latte and 4.8g per 100ml for Rodd’s Original Latte. For a zero-sugar choice, check the prepared serving and any additions.
What should I choose if I am avoiding caffeine?
Look for a product explicitly labelled decaffeinated, such as Nolo Decaf Classic Cold Brew Oat Latte. Do not use the fact that coffee is served cold to judge its caffeine content; if you need to track an exact amount, check the product’s caffeine information.
What caffeine check matters during pregnancy?
The NHS advises no more than 200mg of caffeine a day during pregnancy, counting caffeine from all sources. Check how much cold brew you will drink alongside other caffeinated products; Marks & Spencer lists 34.6mg per 100ml for its Plant Kitchen latte and warns that it is not recommended for pregnant women.
Is a dairy-free oat cold brew suitable for someone avoiding other allergens?
Not automatically. Nolo contains oat, while Marks & Spencer says its Plant Kitchen oat latte is not suitable for coeliacs or people with soya or wheat allergy. Read the ingredient and allergen statement on the exact pack.
Is a meal-style coffee drink the same choice as a light tea-break coffee?
No: consider whether the drink is standing in for a missed meal. Tesco Groceries lists 500 kcal, 30g protein and 9g fibre in a 500ml yfood Cold Brew Coffee pack, compared with 12 kcal in a prepared 200ml glass of its unsweetened black-coffee concentrate before additions.
