Who are you serving?

Guests with different coffee preferences

If some guests prefer black coffee and others add milk or a milk alternative, a concentrate with clear mixing instructions gives you a shared starting point. You will also need water and ice.

Guests with dietary requirements

Keep the current packaging to hand rather than assuming a plant-based drink suits everyone. M&S describes its oat cold-brew latte as dairy-free but says it is not suitable for coeliacs or people with a wheat allergy.

Guests who prefer decaf

Offer a clearly separate decaffeinated drink instead of diluting regular cold brew. Sainsbury's lists a Nolo ready-to-drink oat latte labelled decaffeinated; check its oat ingredient against guests' requirements.

What matters when choosing cold brew?

Start with the number of drinks you plan to make, then decide which guests need a separate prepared or decaf option.

Priority What to check Your needs
Flexible servings Check the concentrate's dilution instructions, pack size and stated servings. Tesco Finest specifies 100ml concentrate with 100ml cold water; Grind specifies 62ml concentrate per serving, mixed with water or milk. I'm making drinks for several people, and some will want black coffee while others will add milk or a milk alternative.
Drink style Distinguish an unsweetened base from a pre-mixed, flavoured latte. For a drink that needs no mixing, check whether the bottle is plain black coffee or a latte. I'd like guests to decide what to add to their coffee, rather than serving everyone the same pre-mixed drink.
Ingredients and allergens Read the current ingredient and allergen label for each drink and any milk alternative. M&S says its dairy-free oat latte is unsuitable for coeliacs and people with a wheat allergy. A guest may avoid dairy, wheat or oats, so I need to identify their drink without relying on a general plant-based label.
Decaf choice Look for an explicitly decaffeinated product and keep it separate from regular coffee. Check the ingredients of a flavoured or oat-based decaf latte too. Some guests would rather have decaf; adding more water to regular coffee would not provide it.
Storage and portions Check the label's instructions after opening and choose a pack format you can use as directed. Sainsbury's says its Nolo oat latte must be refrigerated and consumed within 24 hours of opening. For a smaller gathering, individual drinks may be easier to portion; for several customised drinks, I can prepare servings from a concentrate.

Mistakes to avoid when serving cold brew

  • Treating concentrate as ready-to-drink coffee

    A concentrate has its own mixing instructions, so pouring it like a finished drink changes the intended strength.

    Follow the product's directions: Tesco Finest specifies 100ml concentrate and 100ml cold water, while Grind specifies 62ml concentrate per serving mixed with water or milk.

  • Assuming every oat drink suits every guest

    Dairy-free does not settle wheat, oat or other ingredient requirements. M&S says its oat cold-brew latte is unsuitable for coeliacs and people with a wheat allergy.

    Keep each drink's current packaging available and check the stated ingredients and allergens before offering it to a guest with a dietary requirement.

  • Using diluted regular coffee as the decaf option

    Adding water changes a drink's concentration; it does not make the coffee decaffeinated.

    Choose an explicitly labelled decaf drink and make it easy to distinguish from regular cold brew.

  • Relying on an older product listing

    Ingredients and storage directions can change, and an online description may not match the pack you serve.

    Check the current label for allergens, preparation and instructions after opening when you buy and serve the drinks.

Coffee-morning cold brew questions

Should I buy concentrate or ready-to-drink cold brew?

Choose a concentrate if you are making several drinks with different water or milk choices and can follow its mixing instructions. Ready-to-drink bottles or cans suit individually prepared servings, including a separate decaf choice.

Can one concentrate make both black cold brew and lattes?

Yes, when its directions permit both water and milk. Tesco says its Finest concentrate can be mixed with cold water and adjusted with milk or a milk alternative; Grind gives directions for mixing its concentrate with water or milk.

Is an oat cold brew suitable for everyone avoiding dairy?

No. M&S describes its oat cold-brew latte as dairy-free but says it is unsuitable for coeliacs and people with a wheat allergy. Check the current label against each guest's requirements.

How can I offer a decaf option?

Set out a separately labelled decaffeinated drink rather than diluting regular cold brew. Sainsbury's lists a Nolo decaf oat latte; check its ingredients if a guest has an oat-related requirement.

What should I check about storage?

Follow each product's current instructions after opening rather than applying one rule to every cold brew. Sainsbury's says its Nolo oat latte should be refrigerated and consumed within 24 hours of opening.
