Hosts serving different coffee preferences
A shared chilled bottle can serve guests who want the same oat latte, while individual latte cans and black cold brew give others a more distinct choice of milk base and flavour.
Who is the drinks table for?
A mixed adult guest list calls for clearly identified choices, rather than one coffee base or flavour for everyone.
Hosts accommodating dairy-free guests
An oat-based drink may provide a dairy-free choice, but its exact label matters: M&S says its Oat Latte Cold Brew is not suitable for coeliacs or people with a wheat allergy, and Rodd's says its oat latte contains gluten.
Hosts including guests who limit caffeine
A labelled decaf option gives guests a choice beyond standard caffeinated cold brew. This matters particularly when a guest is pregnant: NHS guidance limits total caffeine from all sources to 200mg a day during pregnancy.
What should you check before choosing?
Decide how the coffee will be served, then check dietary suitability, caffeine and flavour on each product’s own label.
| Priority | What to check | Your needs |
|---|---|---|
| Serving format | Check whether it is a ready-to-drink can, a refrigerated shared bottle or a concentrate that needs diluting. For an opened bottle, follow its own storage instructions. | I want guests to serve themselves without confusing the drinks. A shared bottle suits several adults choosing the same coffee; separate cans keep individual choices labelled. |
| Milk and oat ingredients | Read the ingredient and allergen information for the exact variant. M&S lists semi-skimmed milk in its Classic Latte and says its dairy-free Oat Latte is not suitable for coeliacs or people with a wheat allergy; Rodd's states that its oat latte contains gluten. | If guests avoid dairy or have an allergy-related requirement, I need them to see which drink is which before pouring. A dairy-free description alone does not settle oat, gluten or wheat suitability. |
| Caffeine | Look for a clearly labelled decaf choice and check caffeine information on the caffeinated product. Coffee Friend UK lists 40.5mg per 100ml for its Sandows cold brew; that figure does not describe other brands. | Some guests may want coffee without choosing a standard caffeinated drink. NHS guidance for pregnancy concerns total daily caffeine from all sources, not just the serving on this table. |
| Flavour and base | Distinguish plain or caramel-flavoured lattes from black coffee. Check the ingredients rather than assuming that every oat drink is unflavoured or every black cold brew has the same composition. | I would like a coffee-led choice alongside creamy or flavoured drinks, so guests are not limited to one sweetness or milk base. |
What could cause problems on the day?

Describing every oat cold brew as allergy-friendly
Dairy-free does not establish gluten or wheat-allergy suitability. M&S specifically excludes its Oat Latte Cold Brew for coeliacs and people with a wheat allergy, while Rodd's states that its oat latte contains gluten.
Keep the original packaging available for guests to read, and identify milk-based and oat-based drinks separately without making blanket suitability claims.
-
Putting out only caffeinated coffee
Caffeine content differs between products. Coffee Friend UK lists 40.5mg per 100ml for Sandows cold brew, while NHS pregnancy guidance limits total caffeine from all sources to 200mg a day.
Put out a clearly labelled decaf or non-caffeinated alternative and let guests check the packaging of any caffeinated drink they choose.

Opening a shared bottle without a storage plan
Rodd's instructs customers to keep its 750ml Original Oat Latte at +1°C to +7°C and use it within 3 days of opening. Sainsbury's lists a 24-hour refrigerated after-opening period for Nolo's decaf oat latte.
Check fridge space and the exact label before serving or keeping leftovers; do not apply one product’s instructions to another.
Opening more than guests will drink can leave a practical burden when the remaining coffee needs refrigeration and use within the stated period.
Which brands illustrate the options?
These product lines show how format and ingredients vary; a brand name alone cannot establish that a drink suits a guest’s requirements.
M&S Food
Its 250ml Classic, Caramel and Oat Latte cold-brew cans offer separate individual choices.
- M&S identifies semi-skimmed milk in the Classic and Caramel variants and describes its Oat Latte as dairy-free.
- M&S says its Oat Latte is not suitable for coeliacs or people with a wheat allergy; check the current pack for the variant being served.
Rodd's
Its 750ml Original Oat Latte is a shared-format oat drink containing cold brew coffee.
- Rodd's specifies refrigeration at +1°C to +7°C and use within 3 days after opening.
- Rodd's states that the drink contains gluten, so its oat base does not make it suitable for every guest avoiding allergens.
Nolo
Its 250ml Decaf Classic Cold Brew Oat Latte provides a caramel-flavoured, decaffeinated individual choice.
- Sainsbury's lists the product as plant-based and dairy-free.
- It contains oat; Sainsbury's instructs customers to refrigerate it after opening and consume it within 24 hours.
Sandows
The 200ml black cold brew listed by Coffee Friend UK is a coffee-and-water option without a latte base.
- Coffee Friend UK lists fresh coffee and filtered water as its ingredients and describes it as dairy-free and sugar-free.
- The retailer reports 40.5mg caffeine per 100ml for this product; guests considering caffeine should check its label rather than use that figure for other cold brews.
Joybuy cold-brew option
This coffee-forward option comes in portions for mixing with water, rather than as a ready-to-serve party bottle or latte can.

J.ZAO Extra-Strong Americano Cold Brew Coffee Liquid, 10 × 25ml pouches
The portioned concentrate offers a black-coffee choice for guests willing to mix their own drink. Its directions suggest diluting each 25ml pouch with about 200ml of cold or hot water; it is not ready to serve straight from the pouch. The product description lists water and Arabica coffee beans, while the title states zero sugar. Check the pack’s caffeine and storage instructions before preparing drinks in advance or presenting them to guests limiting caffeine.
Questions about serving cold brew
Should cold brew be the main drink at a christening?
Treat cold brew as an adult coffee choice alongside water and other non-caffeinated refreshments. If you serve caffeinated coffee, a clearly identified decaf option gives guests another coffee-style choice; Sainsbury's lists Nolo's oat latte as decaffeinated.
Is dairy-free oat cold brew suitable for coeliacs or guests with a wheat allergy?
Not automatically. M&S describes its Oat Latte Cold Brew as dairy-free but expressly says that product is not suitable for coeliacs or people with a wheat allergy. Keep the exact product’s packaging available rather than describing oat coffee as generally allergy-safe.
How should chilled cold brew be stored after opening?
Follow the instructions for the particular drink. Rodd's specifies +1°C to +7°C and use within 3 days after opening for its 750ml Original Oat Latte; Sainsbury's says to refrigerate Nolo's decaf oat latte after opening and consume it within 24 hours. Check a different product’s label rather than borrowing either period.
