Shoppers watching sugars alongside snacks
If the snack is already sweet, you may prefer an unsweetened black coffee or a drink labelled 0g sugars. A concentrate also lets you choose what to add when preparing it.
Who is choosing?
Dairy-free and lactose-free coffee shoppers
A dairy-free oat latte and a lactose-free milk latte meet different requirements. Check the ingredients and allergens of the specific drink rather than relying on its coffee style.
Shoppers reducing caffeine for later sessions
Cold brewing does not make a coffee decaffeinated. Look for a decaf variant if reducing caffeine matters, and check the pack of any caffeinated option for serving information.
What should you check?
Start with the distinction that matters most to you—sugars, milk ingredients or caffeine—then check whether the drink is ready to serve or needs preparing.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Compare ‘unsweetened’, ‘no added sugar’ and the ‘of which sugars’ figure per 100ml or serving. Check additions if using a concentrate. | I want to choose how much sweetness goes into my drink. Sainsbury’s lists 4.8g sugars per 250ml can for Nolo’s no-added-sugar oat latte, so that claim alone would not meet a 0g-sugars requirement. |
| Caffeine | Look for a decaf designation or the caffeine amount for the serving you plan to drink. Do not assume cold brew has less caffeine. | For a later gaming session, I would look for decaf rather than judge caffeine by the words ‘cold brew’. The NHS advises consuming caffeine in moderation. |
| Milk ingredients | Distinguish dairy-free oat drinks from lactose-free milk drinks. Read the full ingredient and allergen declaration. | I need to avoid dairy itself, not just lactose; an oat latte may fit that requirement, but I still need to check its other ingredients. |
| Preparation and storage | Check whether the coffee needs dilution and whether it requires chilling or has a time limit after opening. | A drink I can open during a session suits me differently from a concentrate I need to mix. For a larger container, I also need to follow its own storage directions. |
Common buying mix-ups
-
Reading ‘no added sugar’ as ‘zero sugars’
Naturally occurring sugars can remain in a latte with no added sugar. Sainsbury’s lists 4.8g sugars per 250ml can for Nolo’s oat latte.
If 0g sugars is your criterion, check the ‘of which sugars’ figure for the serving rather than relying on the front-of-pack phrase.
-
Assuming cold brew is low in caffeine
A cold-brew coffee can still contain caffeine; decaf is a separate product choice. The NHS advises pregnant people not to exceed 200mg of caffeine a day from all sources.
Choose a decaf variant when reducing caffeine, and check caffeine information for the specific caffeinated drink and serving.
-
Confusing lactose-free with dairy-free
Tesco describes Starbucks Skinny Latte as a lactose-free milk drink, whereas M&S describes its oat cold brew as dairy-free. The claims do not mean the same thing.
Match the claim to what you need to avoid, then read the current ingredient and allergen declaration.
-
Overlooking directions after opening
Chilled coffees can have different instructions once opened. Sainsbury’s directions for Nolo specify refrigeration and consumption within 24 hours; its Rodd’s listing allows up to three days when refrigerated.
Check the directions on your own container before deciding whether a multi-serve format suits your plans.
Brand and product references
These examples show how particular drinks differ; a brand name alone does not establish a drink’s sugars, milk ingredients or caffeine.
Tesco Finest
An unsweetened cold-brew concentrate for shoppers who want to prepare their own drink.
- Tesco Groceries describes its 500ml concentrate as unsweetened and cold-water extracted for several hours.
- It needs preparing rather than serving as a ready-made latte; check the pack if caffeine per serving matters.
M&S
Cold-brew latte variants with different milk ingredients.
- M&S Food describes an oat version as dairy-free and a classic version as containing semi-skimmed milk.
- Check the chosen variant’s nutrition label rather than assuming either latte has 0g sugars.
Sandows
A ready-to-drink black cold brew rather than a milk-based latte.
- Coffee Friend UK lists its Sandows cold brew as dairy-free, with 0g sugars.
- It is a caffeinated option; check the current pack for the amount in the serving you drink.
Nolo
A decaf, dairy-free cold-brew oat latte.
- Sainsbury’s describes the 250ml can as decaffeinated, dairy-free and made without added sugar or sweeteners.
- No added sugar does not mean zero sugars: the listing gives 4.8g sugars per can. It contains oat.
Starbucks
A chilled latte reference for a shopper seeking lactose-free milk, rather than a confirmed cold brew.
- Tesco Groceries describes Starbucks Skinny Latte as a lactose-free milk drink with no added sugar.
- It contains milk and sweetener; do not treat lactose-free as dairy-free or this iced coffee as confirmed cold brew.

Questions about cold brew
Does ‘no added sugar’ mean a cold-brew latte has no sugars?
No. Naturally occurring sugars can remain: Sainsbury’s lists Nolo’s no-added-sugar oat latte at 1.9g sugars per 100ml and 4.8g per 250ml can. Check the nutrition panel when zero sugars matters to you.
Which cold-brew format lets me choose what goes into my drink?
An unsweetened concentrate lets you choose the dilution and any milk or other additions. Tesco Groceries describes its Finest cold brew as an unsweetened concentrate; check its preparation directions and the ingredients of anything you add.
Is lactose-free coffee also dairy-free?
No. Tesco describes Starbucks Skinny Latte as a lactose-free milk drink, while M&S describes its oat cold brew as dairy-free. Read the specific pack’s ingredients and allergens to match your requirement.
Should I choose decaf for a later gaming session?
Choose a product labelled decaf if your aim is to reduce caffeine; cold brew is not inherently decaffeinated. Sainsbury’s describes Nolo’s oat cold-brew latte as decaffeinated. The NHS advises consuming caffeine in moderation and advises pregnant people not to exceed 200mg a day from all sources.
What should I check before opening a chilled coffee?
Check the current pack’s ingredients, allergens, nutrition, date and storage directions, as well as caffeine information where supplied. Follow that drink’s instructions after opening: Sainsbury’s lists different refrigerated consumption periods for Nolo and Rodd’s.
