Managers stocking a shared drinks station
A larger format needs space in the fridge and a plan for cups, mixing, measured portions and cleaning. Concentrate can meet a two-litre serving target without requiring one large ready-to-drink bottle.
Who is buying for the office?
Teams with different milk and allergen needs
Keep ingredient information available for each option. M&S Classic Latte Cold Brew contains semi-skimmed milk; M&S says its Oat Latte Cold Brew is not suitable for people with coeliac disease or a wheat allergy.
Buyers planning clearly measured servings
Check caffeine against the maker’s stated serving size rather than the bottle size. Grind lists 101mg per 62ml serving of its concentrate, while the Nescafé vanilla espresso concentrate listed by Sainsbury’s gives 94mg per prepared glass.
What should you check before choosing?
Decide whether the office needs cold brew specifically, simple pouring or individually labelled drinks. Then check how each product is prepared and served.
Cold-brew concentrate
Choose when: The office can measure servings and provide water or milk; Grind’s stated 1:1 mix makes one litre from a 500ml carton.
Allow for: Mixing, cups, cleaning and the caffeine amount in each measured serving.
Multiserve iced coffee
Choose when: Pouring from a shared bottle matters more than meeting a strict cold-brew requirement.
Check: Iced coffee is not necessarily cold brew, and a shared pack still needs an opened-pack storage plan.
Individual cold-brew drinks
Choose when: Each person needs access to the ingredients on their own sealed pack, without a shared preparation station.
Allow for: More individual packs; check each dairy or oat variant against the intended drinkers’ requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Format and yield | Check whether the drink is cold brew, iced coffee or concentrate. Use the exact pack volume and mixing ratio to calculate prepared yield: Grind states that its 500ml cold-brew concentrate makes one litre at a 1:1 mix. | We need enough for several people, but a shared bottle is useful only if we can prepare or serve it as the label directs. |
| Serving size and caffeine | Compare caffeine on the stated serving basis. Grind lists 101mg per 62ml concentrate serving; Sainsbury’s lists 94mg for a prepared glass made with 30ml Nescafé vanilla espresso concentrate and 150ml milk. | I want to know how much coffee goes into my glass rather than guess from the size of the communal pack. |
| Ingredients and allergens | Read the current label for the exact variant. M&S Classic Latte Cold Brew contains semi-skimmed milk; M&S says its dairy-free Oat Latte Cold Brew is unsuitable for people with coeliac disease or a wheat allergy. | Different colleagues need to be able to identify a suitable drink without assuming that an oat option works for everyone. |
| Storage and dates | Check the use-by date, required storage temperature and instructions after opening. The Food Standards Agency warns that food stored too long or at the wrong temperature can cause food poisoning. | Can we refrigerate an opened pack and finish it within the period printed on its label? |
What can go wrong with a shared format?

Treating cold brew, iced coffee and concentrate as the same thing
A concentrate needs preparation, while a ready-to-drink iced coffee is already mixed and may not be cold brew. Pack volume alone therefore does not tell you how much drink you can serve.
Check the exact product’s description, mixing ratio, prepared yield and serving directions before calculating the office quantity.
-
Pouring without checking the caffeine serving
A large container does not define a portion. Grind states 101mg of caffeine per 62ml serving of its concentrate, and the Nescafé prepared glass listed by Sainsbury’s contains 94mg.
Keep the stated serving instructions beside a communal drink and offer a non-caffeinated choice.
-
Assuming every oat latte suits every dietary requirement
M&S describes its Oat Latte Cold Brew as dairy-free but says it is unsuitable for people with coeliac disease or a wheat allergy. Its Classic Latte Cold Brew contains milk.
Keep the current packs or ingredient panels accessible and choose alternatives according to the people who will drink them.
-
Opening a shared pack without a storage plan
The Food Standards Agency warns that incorrect temperature or prolonged storage can make food unsafe. An unopened product’s date does not replace its instructions for use after opening.
Check fridge space, the use-by date and the pack’s opened-storage instructions; make someone responsible for marking when it was opened.
An unfinished opened pack may have to be discarded if the team cannot use it within its stated period.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 10 × 25ml pouches
The individual pouches offer a way to measure portions at an office drinks station. The product information directs users to dilute a pouch in about 200ml of water but also calls the product ready to drink, so check the delivered pack before planning servings. If cold-brew extraction is essential, confirm it for this variant; also check caffeine per prepared serving and storage instructions.

Office Fish Roasted Sweet Potato Flavoured Cold Brew Freeze-Dried Black Coffee Powder, 18g
This is an individually prepared powder rather than a bottle for shared pouring. The product information describes nine sachets and a cold-water direction of 150–180ml per sachet. Check caffeine per prepared serving before setting it out for communal use.
Questions about office cold brew
Do we need a two-litre ready-to-drink cold-brew bottle?
Not necessarily. Tesco and Sainsbury’s list smaller concentrates and multiserve iced coffees, while M&S lists 250ml cold-brew drinks. If the office needs two litres of cold brew, calculate the prepared yield of a concentrate using that product’s own mixing instructions rather than assuming a single large bottle will suit.
How much Grind concentrate makes two litres?
Grind says one 500ml carton makes one litre when mixed 1:1 with water or milk, so two cartons make two litres on that stated basis. Check another concentrate’s own label before using the same calculation.
Should a shared drinks station include a non-caffeinated choice?
Yes, it gives colleagues an option besides the coffee being served. For the coffee itself, display the maker’s portion and caffeine information: Grind lists 101mg per 62ml concentrate serving, while Sainsbury’s lists 94mg per prepared glass of Nescafé vanilla espresso concentrate.
Is an oat cold-brew latte suitable for everyone avoiding dairy?
No. M&S describes its Oat Latte Cold Brew as dairy-free but says it is unsuitable for people with coeliac disease or a wheat allergy. Read the current pack for the exact variant and keep another option available where needed.
What happens to a shared coffee bottle after opening?
Follow that product’s temperature and opened-pack instructions, and do not use it after its use-by date. The Food Standards Agency warns that food stored too long or at the wrong temperature can cause food poisoning; mark the opening date so the team can follow the pack’s stated period.
