For a school-holiday lunch, choose a concentrate when adults want to prepare their coffees differently; a ready-to-drink latte or black cold brew avoids mixing each serving. Check the milk base, oat-product warnings and storage instructions before buying. For children, Wirral Community Health and Care NHS Foundation Trust recommends water or milk and advises avoiding high caffeine intakes, especially for young children.
Who is each format for?
Start with how the adults at lunch want their coffee served, then check any dietary requirements separately.
Adults serving several guests
A concentrate lets guests prepare separate drinks from one coffee base. Tesco Groceries gives a water-dilution method for its Finest concentrate; check that bottle’s instructions rather than applying the same ratio to another brand.
Adults looking for a dairy-free latte
M&S offers an oat cold-brew latte for a ready-to-drink option without dairy. Its product warning says it is not suitable for coeliacs or people with a wheat allergy, so dairy-free alone is not enough to establish suitability.
Parents planning a mixed-age lunch
Keep the adults’ coffee choice separate from drinks for children. Wirral Community Health and Care NHS Foundation Trust identifies water and milk as the preferred drinks for children and cautions against high caffeine intakes, particularly for young children.
What should you check?
Decide whether each adult wants to mix a drink or open a ready-to-drink serving, then compare the exact product labels.

What to check |
Your needs |
| Serving flexibility |
Check the concentrate’s dilution directions, bottle size and whether the label permits other mixers. Tesco Finest directs shoppers to combine 100 ml concentrate with 100 ml cold water for a glass. |
I’m making coffee for several adults who may want to prepare their drinks differently. |
| Milk and allergens |
Read the ingredient and allergen statements on the exact drink. M&S Classic Latte contains semi-skimmed milk; M&S warns that its oat latte is not suitable for coeliacs or people with a wheat allergy. |
A ready-to-drink latte would be handy, but I need to distinguish the milk version from the oat version. |
| Sweetness |
Compare ingredient lists and nutrition panels rather than assuming cold brew is unsweetened. M&S lists sugar in its Classic Latte; an unflavoured concentrate leaves additions to the person preparing it. |
I’d like to decide what goes into my glass instead of assuming every cold-brew drink has the same sweetness. |
| Preparation and storage |
Check whether the drink is ready to open or needs diluting, then read the opened-bottle instructions. Tesco Groceries says its Finest concentrate should be refrigerated and used within four weeks of opening; its Grind concentrate has a seven-day instruction. |
For repeat holiday lunches, I want a pack I can use within its stated opened life. |
| Children’s drinks |
Check caffeine and any child-suitability statement on the exact pack. Wirral Community Health and Care NHS Foundation Trust advises avoiding high caffeine intakes, especially for young children; Tesco Groceries labels its Grind concentrate not suitable for children. |
I need a separate drink for the children rather than putting the adults’ coffee on the shared lunch table as a default. |
Common buying mistakes
-
Assuming every cold brew is black and unsweetened
Cold-brew products include concentrates and pre-mixed lattes. M&S lists milk and sugar in its Classic Latte, so the words “cold brew” do not tell you everything in the drink.
Compare the ingredients and nutrition panel of the exact bottle or can before choosing between a plain coffee base and a latte.
-
Using “dairy-free” as the whole allergen check
M&S states that its oat cold-brew latte is not suitable for coeliacs or people with a wheat allergy.
For someone with either requirement, read the current on-pack warning rather than relying on the absence of dairy.
-
Serving adults’ cold brew to children by default
Coffee contains caffeine. Wirral Community Health and Care NHS Foundation Trust advises avoiding high caffeine intakes, especially for young children, and Tesco Groceries labels its Grind concentrate not suitable for children.
Keep a separate child-appropriate drink available and check the statement on the coffee pack.
-
Assuming all opened concentrates keep for the same time
Tesco Groceries gives four weeks refrigerated after opening for its Finest concentrate, but seven days for its Grind concentrate.
Choose a pack size you can use within the exact product’s instructions, and follow its refrigeration directions after opening.
Brands and retailers to compare
These references cover different products and shop ranges; an iced-coffee listing does not establish that every drink in it is cold brewed.
Tesco
Tesco Groceries lists a Finest unsweetened cold-brew concentrate for preparing coffee by the glass.
- Its stated serving method combines 100 ml concentrate with 100 ml cold water.
- The opened bottle requires refrigeration and use within four weeks; it is not a ready-to-drink lunch can.
M&S
M&S lists Classic Latte and Oat Latte cold-brew drinks in 250 ml formats.
- The two versions offer distinct semi-skimmed-milk and dairy-free oat bases.
- The oat version is not suitable for coeliacs or people with a wheat allergy; check the current label.
Waitrose
The Waitrose & Partners iced-coffee category includes concentrated and ready-to-drink formats.
- Its listing gives shoppers different serving formats to compare.
- An iced-coffee category label does not confirm cold-brew extraction, ingredients or allergens for every drink; inspect the individual product.
Sainsbury’s
Sainsbury’s lists iced-coffee concentrates alongside larger, pre-mixed latte formats.
- The category allows a comparison between drinks to prepare and drinks to pour.
- Check each product page for its preparation method and ingredients; the category does not establish that every item is cold brewed.
Sandows
Coffee Friend describes a 200 ml Sandows ready-to-drink black cold brew made with coffee and filtered water.
- The listed drink offers a plain, single-serve alternative to a latte or a concentrate.
- Check the current pack details and retailer listing before choosing it for lunch.

Cold-brew questions
Should children have cold brew with a school-holiday lunch?
Do not make caffeinated cold brew the default children’s drink. Wirral Community Health and Care NHS Foundation Trust recommends water and milk for children and advises avoiding high caffeine intakes, especially for young children. Check the exact coffee pack too: Tesco Groceries labels its Grind concentrate not suitable for children.
How do you prepare cold-brew concentrate for lunch?
Follow the directions on the bottle you buy. Tesco Groceries instructs shoppers to mix 100 ml of its Finest concentrate with 100 ml cold water for a glass; do not assume another concentrate uses the same ratio.
How long does opened cold-brew concentrate keep?
It depends on the product’s opened-life instructions. Tesco Groceries says to refrigerate its Finest concentrate and use it within four weeks of opening, while its Grind concentrate has a seven-day instruction. Follow the exact pack rather than a general rule for concentrates.
Is an oat cold-brew latte suitable for someone avoiding wheat?
Do not assume so. M&S states that its dairy-free Oat Latte Cold Brew is not suitable for people with a wheat allergy or for coeliacs. Check the current label against the person’s dietary requirements.
