A 2-litre bottle is not the only way to serve cold coffee after dinner: Tesco Groceries lists a 500ml cold-brew concentrate and M&S lists 250ml cold-brew lattes, while larger iced coffees listed by Sainsbury's and Waitrose are not necessarily cold brew. Choose concentrate if guests want different additions, but check its preparation directions before deciding how much to buy; choose ready-to-drink lattes for individual servings, or a larger iced coffee if bottle volume matters more than the brewing method.
If some guests take coffee black and others add milk, a plant drink or ice, an unsweetened concentrate lets you prepare each glass separately. Tesco Groceries lists a 500ml cold-brew concentrate; check its pack directions before working out how many drinks it will make.
M&S lists 250ml Classic and Oat cold-brew lattes for individual servings. The Classic contains semi-skimmed milk, while M&S describes the oat version as dairy-free. Neither is a shared 2-litre bottle.
If a larger ready-to-drink bottle matters more than cold-brew extraction, consider the distinction between the two categories. Sainsbury's lists 750ml and 1-litre iced coffees, and Waitrose lists 750ml iced coffees; those listings do not establish that the drinks are cold brew.
Start with the format you intend to serve—made-to-order glasses, individual lattes or a larger bottle—then check the details that matter for your guests.
| Priority | What to check | Your needs |
|---|---|---|
| Serving volume | Check bottle or pouch volume, whether the drink is concentrated, and any on-pack preparation directions. Tesco Groceries lists a 500ml concentrate; Sainsbury's lists some 750ml and 1-litre ready-to-drink iced coffees. | I'm serving several people and need to know how much drink I can prepare. A 500ml concentrate is not itself a 2-litre bottle, and its finished volume depends on the pack directions. |
| Serving flexibility | Check whether the coffee is unsweetened concentrate or a latte with milk or oat drink already added. Tesco Groceries describes its cold-brew concentrate as unsweetened; M&S lists pre-made dairy and oat lattes. | Some guests want coffee black, while others may add milk, a plant drink or ice. Preparing glasses separately gives me control over those additions. |
| Cold brew or iced coffee | Read the product description for its stated category and preparation method. The larger coffees in the cited Sainsbury's and Waitrose listings are labelled iced coffee, which does not by itself establish cold-brew extraction. | I'd accept a larger iced coffee if it is ready to pour, but I don't want to mistake it for cold brew when the brewing method matters to me. |
| Ingredients and allergens | Read the current ingredients and allergen declaration for each drink. M&S describes its Classic cold-brew latte as containing semi-skimmed milk and its Oat Latte as dairy-free. | One guest avoids dairy, so I need to check the actual pack rather than assume every cold-brew drink has the same ingredients. |
| Evening serving | Check caffeine information, serving size and whether the product is a soft coffee or a coffee liqueur. Tesco Groceries and Waitrose also list cold-brew coffee liqueurs. | I want to know what I'm serving after dinner, particularly if guests are watching their caffeine intake or do not want alcohol. |
| Storage and date | Follow the specific pack's storage instructions and use-by date. The Food Standards Agency warns that food kept too long or at the wrong temperature can cause food poisoning. | I'm buying ahead for dinner and need to keep the drinks as their packs direct until they are served. |
Tesco Groceries lists its cold-brew concentrate in a 500ml bottle. That pack volume does not tell you the finished amount of coffee or how many dinner servings it will provide.
Check whether the product needs mixing and follow its on-pack preparation directions before deciding how many packs to buy.
Sainsbury's and Waitrose list larger iced coffees, but those listings do not establish that the drinks were cold brewed. A larger bottle may solve a serving-volume problem without meeting a cold-brew preference.
If cold-brew extraction matters to you, check the exact product description rather than relying on the bottle size.
M&S describes its Classic Latte as containing semi-skimmed milk and its Oat Latte as dairy-free. Cold-brew search results can also include coffee liqueurs, which are a different kind of drink.
Check the product category and current ingredients and allergen declaration on each pack, especially when serving someone with a dietary requirement.
Serving coffee cold does not establish its caffeine content. M&S describes its Classic cold-brew latte as a double-shot espresso drink, so check the caffeine information and the amount being served.
If serving someone who is pregnant, note that the NHS advises no more than 200mg of caffeine a day during pregnancy, including caffeine from other sources.
These examples show how cold-brew formats differ; check the particular product rather than treating a brand name as a promise of bottle size or ingredients.
Tesco Groceries lists a 500ml unsweetened cold-brew concentrate for preparing drinks with individual additions.
M&S lists 250ml Classic and Oat cold-brew lattes intended as individual ready-to-drink options.
Sandows describes its own coffee as cold brewed with water and triple filtered.
This pouch format can be prepared as separate drinks for dinner guests. It is not a single 2-litre bottle of ready-to-pour coffee.

The ten individual 25ml pouches allow drinks to be mixed separately for guests, rather than poured from a shared bottle. Check the pack's preparation directions to plan servings, and its caffeine information before evening serving.
Plan around the exact product and pack size rather than assuming that format. Tesco Groceries lists a 500ml cold-brew concentrate and M&S lists 250ml cold-brew lattes; the larger 750ml and 1-litre coffees listed by Sainsbury's and Waitrose are not established as cold brew. Check the current product description if both a 2-litre bottle and cold-brew extraction are essential.
No caffeine amount follows from the name alone: check the particular drink's caffeine information and serving size, especially for a concentrate or a double-shot latte. For pregnancy, the NHS advises no more than 200mg of caffeine a day from all sources.
Read the current pack's ingredients and allergen declaration. M&S describes its Classic cold-brew latte as containing semi-skimmed milk and its Oat Latte as dairy-free with oat milk, but the label of the drink you serve is the relevant check.
Follow the drink's own storage instructions and use-by date. The Food Standards Agency warns that keeping food too long or at the wrong temperature can cause food poisoning, so check the pack when buying ahead and before serving.
