Start with who will drink it: the NHS identifies water and milk as the best drinks for children, so caffeinated cold brew should not be the default with a child’s after-school snack. For an adult, unsweetened concentrate allows control over preparation, a ready-to-drink latte avoids mixing, and black cold brew offers a coffee-and-water option; choose a product explicitly described as decaffeinated when avoiding caffeine. Check the exact pack for caffeine information, ingredients and storage instructions.
Who is choosing the drink?
Parents choosing a child’s after-school drink
The NHS identifies water and milk as the best drinks for children. That makes the intended drinker and the product’s caffeine status more important than whether the coffee is served cold or alongside a snack.
Adults mixing coffee alongside a snack
An unsweetened concentrate suits someone who wants to choose how much water or milk to add. Tesco Finest’s concentrate, for example, has a stated mixing instruction rather than being a ready-to-drink latte.
People checking caffeine or ingredients
Sainsbury’s describes the Nolo oat latte as decaffeinated and dairy-free, while the M&S cold-brew latte contains semi-skimmed milk. Check the particular product rather than relying on the word “latte” or “cold brew” to establish what it contains.
What matters when choosing cold brew?
Decide who will drink it first, then compare the ingredients and preparation needed for the snack-time occasion.

What to check |
Your needs |
| Caffeine |
Look for an explicit decaffeinated description if avoiding caffeine. If an amount matters, check the caffeine information on the exact pack rather than inferring it from the cold-brew format. |
I’m choosing a drink for a child, or I want to avoid caffeine. The NHS identifies water and milk as the best drinks for children; Sainsbury’s describes its Nolo oat latte as decaffeinated. |
| Sugar and flavour |
Compare ingredients and sugars using the stated serving or nutrition basis. Tesco Finest labels its concentrate unsweetened; M&S lists sugar as an ingredient and 3.8g sugars per 100g in its Classic Latte. Sainsbury’s lists 4.8g sugars per 250ml Nolo can despite its no-added-sugar description. |
I’d rather decide what to add to my coffee, or I want to know how sweet a ready-to-drink latte is before pairing it with a snack. |
| Milk and oat |
Read the current ingredients and allergen statement. The M&S latte contains semi-skimmed milk; the dairy-free Nolo latte contains oat. Coffee Friend UK describes Sandows black cold brew as coffee and water. |
Milk or oat affects my choice, so a coffee-style name alone does not tell me whether this particular drink fits. |
| Preparation and storage |
Check whether the drink needs mixing and read its after-opening instructions. Tesco Finest instructs buyers to combine 100ml concentrate with 100ml cold water, then refrigerate the opened bottle and use it within four weeks. |
A can or bottle is useful when I want a drink without mixing; a concentrate makes more sense when I want to prepare and adjust it myself. |
What should you avoid overlooking?
-
Assuming a cold drink contains little caffeine
Cold brew is still coffee unless the product is explicitly decaffeinated. Coffee Friend UK lists 40.5mg caffeine per 100ml for its Sandows black cold brew, while the NHS identifies water and milk as the best drinks for children.
For a child’s snack, start with the drinker rather than the flavour. If avoiding caffeine in a coffee-style drink, look for an explicitly decaffeinated product and check its pack.
-
Expecting every cold brew to have the same sugar content
Tesco Finest describes its concentrate as unsweetened, whereas the M&S Classic Latte contains added sugar and lists 3.8g sugars per 100g. Any additions to a concentrate also change the finished drink.
Compare the ingredients and nutrition panel for the product you intend to serve, including anything you plan to mix into it.
-
Overlooking ingredients or an opened bottle
The M&S latte contains milk, the Nolo oat latte contains oat, and Tesco Finest instructs buyers to refrigerate its concentrate after opening and consume it within four weeks.
Check the allergen statement and storage directions before choosing a latte or a bottle of concentrate.
-
Confusing coffee liqueur with cold coffee
Waitrose & Partners places Tia Maria Cold Brew Coffee Liqueur among liqueurs and speciality spirits. An alcoholic product is not a substitute for an after-school cold coffee, particularly when a child might be served.
Check the product category and alcohol information rather than relying on “cold brew coffee” in the name.
Relevant brand and retailer references
These examples show why the exact product matters: concentrate, dairy latte, decaf oat latte, black coffee and coffee liqueur serve different purposes.
Tesco Finest
Tesco’s unsweetened cold-brew concentrate is a mix-at-home option rather than a ready-to-drink latte.
- Tesco states that the 500ml product uses 100% Arabica coffee and gives a mixing instruction of 100ml concentrate to 100ml cold water.
- It needs preparation; Tesco says to refrigerate it after opening and consume it within four weeks. Check the pack if a particular caffeine amount matters.
M&S
M&S Classic Latte Cold Brew Coffee is a chilled dairy latte for someone who wants a drink without mixing.
- M&S describes 100% Arabica cold brew combined with a double espresso shot and semi-skimmed milk.
- It contains milk and added sugar; M&S lists 3.8g sugars per 100g. Check the pack if you need its caffeine quantity.
Sainsbury’s
Sainsbury’s lists Nolo Decaf Classic Cold Brew Oat Latte as a decaffeinated, dairy-free coffee-style option.
- The Nolo listing describes a plant-based drink with no added sugar or sweeteners.
- It is caramel-flavoured and contains oat; Sainsbury’s lists 4.8g sugars per 250ml can. Check its current ingredients and allergen statement.
Sandows
The Sandows product described by Coffee Friend UK is a ready-to-drink black cold brew made with coffee and filtered water.
- Coffee Friend UK describes it as sugar-free and dairy-free.
- The retailer lists 40.5mg caffeine per 100ml, so this product is not a decaffeinated option.
Waitrose
The Waitrose & Partners cold-brew example here is Tia Maria Cold Brew Coffee Liqueur, an alcoholic product.
- Waitrose & Partners places it among liqueurs and speciality spirits. Do not choose it as an after-school cold coffee.

Frequently asked questions
Should caffeinated cold brew be a child’s usual after-school drink?
No. The NHS identifies water and milk as the best drinks for children. If a coffee-style cold drink is wanted while avoiding caffeine, look for a product explicitly described as decaffeinated rather than assuming cold brew contains little caffeine.
How can I control sweetness in a cold-brew drink?
An unsweetened concentrate lets you decide what to add when preparing it. Tesco Finest describes its concentrate as unsweetened, while the M&S Classic Latte lists sugar as an ingredient and 3.8g sugars per 100g; check the finished drink’s ingredients and nutrition panel.
Does a dairy-free cold-brew latte still need an ingredient check?
Yes. Sainsbury’s describes the Nolo decaf oat latte as dairy-free, but its ingredients include oat. Read the current pack’s ingredients and allergen statement for your particular requirements.
How long can cold-brew concentrate be kept after opening?
Follow the instructions for the particular product. Tesco Finest says to refrigerate its concentrate once opened and consume it within four weeks; do not apply that instruction to a different concentrate or ready-to-drink product without checking its pack.
