A 2-litre bottle is not necessary if smaller, separately served drinks will cover your afternoon tea break. Tesco Groceries and Waitrose & Partners list 750ml iced coffees, but their names do not establish that they are cold brew; if a larger batch of cold brew is the requirement, allow time to make and chill it yourself. Check the intended portions, ingredients and caffeine information before choosing what to serve.
If several people will have coffee, work out the number and size of servings before choosing a bottle. Tesco Groceries and Waitrose & Partners list 750ml iced coffees; compare that volume with what you plan to pour rather than treating “multi-serve” as a serving count.
If the brewing method matters, look for a product explicitly labelled cold brew. Marks & Spencer uses that description for its 250ml lattes, while the larger drinks in the cited Tesco Groceries and Waitrose & Partners listings are described as iced coffee or latte.
When serving other people, check each drink’s ingredient and allergen information and the caffeine in the portions you intend to pour. Marks & Spencer’s oat latte, for example, carries warnings for coeliacs and people with a wheat allergy.
Decide whether you need cold brew specifically, a drink you can open and serve immediately, or enough coffee to prepare in advance for the group.
| Priority | What to check | Your needs |
|---|---|---|
| Volume and drink type | Read the labelled volume and whether the drink is cold brew, ready-to-drink iced coffee or concentrate. Tesco Groceries and Waitrose & Partners list 750ml iced coffees and 500ml concentrates; the format names are not interchangeable. | I need enough for the portions I plan to serve, and I want to know whether I am buying cold brew or another chilled coffee drink. |
| Preparation | Check whether the drink can be poured straight away or needs mixing, steeping or filtering. Waitrose & Partners’ cold-brew recipe calls for overnight steeping, then straining and chilling for up to two days. | If coffee must be ready when guests arrive, I would choose a suitable ready-to-drink format. If I can prepare it the night before, a home-made batch is another option. |
| Ingredients and allergens | Read the current ingredients and allergen warnings for the exact flavour. Marks & Spencer describes semi-skimmed milk in its Classic Latte Cold Brew and warns that its Oat Latte Cold Brew is not suitable for coeliacs or people with a wheat allergy. | I want to check the drink against my guests’ requirements before serving it, rather than assuming every coffee or oat-based drink has the same ingredients. |
| Caffeine per portion | Check the pack’s caffeine information and the amount going into each cup. When caffeine intake matters, include other sources consumed that day; NHS advice sets a limit of 200mg per day during pregnancy. | A shared container makes it easy to pour different-sized portions, so I want to understand the caffeine in each serving. |
A 750ml iced coffee, a 500ml concentrate and a 1-litre latte represent different volumes and drink types in the Tesco Groceries and Waitrose & Partners listings. None becomes a 2-litre cold brew simply because it is served cold.
Check the volume and product description separately. If you need 2 litres of prepared cold brew, plan the batch and its preparation time.
Marks & Spencer labels its Oat Latte Cold Brew as unsuitable for coeliacs and people with a wheat allergy. The drink’s format alone cannot establish its allergen suitability.
Check the current pack for ingredients and allergen warnings for every flavour you intend to serve.
The caffeine consumed depends on what is in the drink and how much each person has, not just the size of the container. This matters when portions differ or guests consume caffeine elsewhere that day.
Use the product’s caffeine information to assess the planned portions. NHS advice says caffeine intake during pregnancy should not exceed 200mg per day.
Marks & Spencer identifies its 250ml Classic Latte and Oat Latte as cold-brew coffee drinks.
Tesco Groceries lists a 750ml Starbucks multi-serve iced coffee, a 500ml Nescafé iced-coffee concentrate and a 1-litre Arctic Coffee caramel latte.
Waitrose & Partners lists 750ml iced coffee and 500ml concentrate formats and publishes a method for preparing cold brew at home.
Coffee Friend lists Sandows as a 200ml cold-brew coffee made with coffee and filtered water.
These cold-brew-labelled options are for preparing separate servings at afternoon tea, rather than opening a 2-litre ready-to-drink bottle.

Ten portioned pouches offer a way to prepare separate cold-brew coffees for guests, rather than pouring from one ready-to-drink bottle. Follow the pack’s mixing directions and check its caffeine and storage information before serving.

This freeze-dried coffee powder is an option for preparing drinks separately, not a ready-to-drink group bottle. Check the pack’s mixing directions, caffeine information and ingredients before making drinks for guests.
No: it is less than 2 litres, and “iced coffee” does not by itself confirm cold-brew preparation. Tesco Groceries and Waitrose & Partners list 750ml iced coffees; compare their labels and volumes with the drink and portions you actually need.
No. Marks & Spencer explicitly calls its 250ml lattes cold brew, while the larger drinks cited by Tesco Groceries and Waitrose & Partners are named iced coffee or latte. Check the description of the exact product if the brewing method matters to you.
Yes, if you follow a recipe that allows for the preparation and storage time. Waitrose & Partners’ cold-brew method says to steep overnight, strain and chill the drink until needed for up to two days; do not assume that holding period applies to a different recipe.
Check the drink’s caffeine information against the size of each planned serving, and account for other caffeine consumed that day. NHS guidance says caffeine intake during pregnancy should not exceed 200mg per day.
Not necessarily. Marks & Spencer labels its Oat Latte Cold Brew as unsuitable for people with a wheat allergy or for coeliacs. Check the current ingredients and allergen statement on the exact drink before serving it.
