Home diners who want to mix their own coffee
A cold-brew concentrate lets you add water or milk to each serving. It is the relevant format if cold-brew preparation and control over the finished drink both matter.
Who each format suits
For coffee after dinner, the useful starting point is whether you want to mix each drink, open one ready-made serving or keep a jar for regular use.
Chilled latte drinkers
A ready-to-drink cold-brew latte avoids measuring and mixing. Check its ingredients if the choice of milk or the presence of sugar matters to you.
Shoppers who want a coffee jar
Instant coffee provides a jarred option for a quick drink at home. Choose it for that preparation routine, rather than expecting the jar itself to provide cold-brew coffee.
What to check before choosing
Cold-brew concentrate
Choose it when: You want a cold-brew base and prefer to mix each drink with water or milk.
Bear in mind: It needs dilution, and opened-pack storage matters if you will only make coffee occasionally.
Ready-to-drink cold-brew latte
Choose it when: You want one chilled, creamy coffee without mixing.
Bear in mind: Its recipe is already set, so check the milk and other ingredients before buying.
Instant-coffee jar
Choose it when: A jar for quick, adjustable home preparation matters more than cold-brew extraction.
Bear in mind: Instant coffee prepared with hot water and then cooled makes iced coffee, not cold brew.
| Priority | What to check | Your needs |
|---|---|---|
| Brewing method | Look for cold-brew preparation if the extraction method matters. NESCAFÉ distinguishes coffee made without heat from coffee brewed and then cooled; an instant jar should not be treated as cold brew. | I want the drink after dinner to be cold brew, not just coffee served over ice. |
| Mixing and ingredients | Check whether the drink is a concentrate to dilute or a pre-mixed latte. Tesco gives a serving of 62ml Grind concentrate mixed with water or milk; Marks & Spencer describes its Classic Latte Cold Brew Coffee as containing semi-skimmed milk. | Some evenings I would choose my own milk or serve the coffee black; on others, I would rather open a finished latte. |
| Caffeine per serving | Compare the labelled serving size with its caffeine information and account for other caffeine consumed that day. Grind states 101mg of caffeine per 62ml serving of its concentrate. | If caffeine intake matters to me, I need to know how much concentrate goes into my cup rather than judging by the size of the carton. |
| Use after opening | Read the exact pack’s storage instructions and opened-pack period. Tesco says its listed Grind concentrate should be refrigerated and consumed within seven days of opening. | I only make cold coffee now and then, so I would check whether I could use a multi-serve carton within its labelled period. |
Common buying mistakes
-
Assuming iced coffee and cold brew mean the same thing
An instant-coffee jar can be used for a cold drink, but dissolving the granules in hot water and cooling the coffee does not make it cold brew. NESCAFÉ distinguishes cold brew by its preparation without heat.
If that brewing method matters to you, choose a product identified as cold brew rather than relying on a picture of an iced drink.
-
Assuming every cold coffee has the same ingredients
A pre-mixed latte and a black concentrate can differ in their milk and other ingredients. Marks & Spencer describes its Classic Latte Cold Brew Coffee as containing semi-skimmed milk.
Read the exact ingredient list and allergen declaration, particularly if you need a dairy-free drink or want to choose what goes into the cup.
-
Overlooking the concentrate serving size
Grind states that a 62ml serving of its concentrate contains 101mg of caffeine. The amount you pour matters when assessing your intake.
Follow the serving directions and check caffeine information for the exact product. For pregnancy, the NHS advises no more than 200mg of caffeine a day in total.
-
Opening a multi-serve carton without checking its storage period
Tesco instructs buyers to refrigerate its listed Grind concentrate and consume it within seven days of opening. That period matters if you make cold coffee infrequently.
Check the pack before choosing a multi-serve format, and consider a single ready-to-drink portion if it better matches how often you will have coffee.
Relevant brand examples
These examples illustrate the different coffee formats; the product label remains the place to check the version you are buying.
Grind
Grind’s 500ml cold-brew concentrate is an example of a multi-serve base for mixing with water or milk.
- Tesco gives a 62ml serving mixed with water or milk and says the carton makes up to eight servings.
- Tesco instructs buyers to refrigerate the concentrate after opening and consume it within seven days; Grind states 101mg of caffeine per 62ml serving.
M&S Food
Marks & Spencer provides examples of both instant-coffee options and a ready-to-drink cold-brew latte.
- Its instant-coffee range includes single-origin granules and decaf options.
- Its 250ml Classic Latte Cold Brew Coffee contains semi-skimmed milk, so check the label if you need to choose the milk yourself.
Starbucks Coffee Craft
The Signature Caramel Flavour product is a flavoured concentrate for mixing, rather than a plain black ready-to-drink coffee.
- Starbucks at Home UK describes a 260ml bottle with eight servings, mixed with water, milk or a milk alternative.
- If cold-brew extraction is essential to your choice, check the product’s brewing description rather than assuming that every coffee concentrate is cold brew.

Questions about cold brew and coffee jars
Is an instant-coffee jar the same as cold brew?
No. NESCAFÉ describes cold brew as coffee made without heat. If you dissolve instant coffee in hot water and then cool it, you are making iced coffee rather than cold brew.
Which format lets me make a creamy coffee after dinner?
Choose a ready-to-drink latte if you want a chilled, pre-mixed drink, or a cold-brew concentrate if you want to add milk yourself. Marks & Spencer’s Classic Latte Cold Brew Coffee contains semi-skimmed milk; Tesco directs buyers to mix its listed Grind concentrate with water or milk.
What should I check if I avoid dairy?
Read the ingredients and allergen declaration for the exact drink. Marks & Spencer describes its Classic Latte Cold Brew Coffee as containing semi-skimmed milk, while a concentrate mixed at home lets you choose what to add to the coffee.
How do I account for caffeine in a concentrate?
Use the labelled serving size and caffeine information, then account for other caffeine consumed that day. Grind states that one 62ml serving of its concentrate contains 101mg of caffeine. For pregnancy, the NHS advises a daily total of no more than 200mg.
How should I store concentrate after opening?
Follow the instructions for the exact product. Tesco says its listed Grind Espresso Cold Brew Coffee Concentrate should be refrigerated and consumed within seven days once opened, so check whether that period fits how often you will use it.
