Coffee drinkers heading to bed soon
If reducing caffeine is the priority, look for a product explicitly labelled decaffeinated rather than assuming a cold drink contains less caffeine. The NHS says caffeine in coffee can make you feel more awake.
Who is each format for?
The time between supper and bed, and how much preparation you want, make a difference to the choice.
People mixing iced coffee at home
A cold-brew concentrate gives you a coffee base to dilute and combine with your choice of milk or plant drink. Follow the product’s serving directions and check its caffeine information if you will drink it late.
Shoppers wanting one chilled drink
A ready-to-drink latte removes the mixing step. Compare the ingredients of the particular dairy or oat version, especially if milk or another allergen affects your choice.
What should you check before choosing?
Start with when you will drink the coffee, then decide whether you want a jar to prepare at home, a concentrate to dilute or a finished chilled drink.
Decaf instant-coffee jar
Choose it when: reducing caffeine matters more than having coffee made by cold brewing.
Bear in mind: instant granules are a different format from cold-brew concentrate; prepare them according to the jar directions before chilling the drink.
Cold-brew concentrate
Choose it when: you want to dilute a coffee base and add your own ingredients.
Bear in mind: cold brewing does not mean decaffeinated. Grind states that a 62 ml serving of its concentrate contains 101 mg of caffeine.
Chilled ready-to-drink latte
Choose it when: you want a single cold drink without measuring or mixing.
Bear in mind: the recipe is already set. M&S describes both its Classic Latte and oat version as containing a double shot of espresso.
| Priority | What to check | Your needs |
|---|---|---|
| Caffeine and timing | Look for an explicit decaffeinated label if reducing caffeine is the aim. For other coffees, compare any stated caffeine amount with the serving you intend to make. | I’m having coffee shortly before bed and don’t want to mistake a cold serving temperature for a decaf label. NHS guidance says caffeine can make people feel more awake. |
| Preparation and format | Check whether the product contains instant granules, concentrate, individual portions or a finished drink. Follow its preparation or dilution directions. | A jar I can prepare at home, an iced drink I can mix myself and a chilled latte I can drink straight away meet different needs. |
| Ingredients and allergens | Read the ingredients and allergen information for the exact drink. Check milk-based and plant-based versions separately rather than relying on a range name. | If I need to avoid an ingredient, I want the label for the particular product I’m buying, not an assumption that all cold coffee is black or dairy-free. |
Common buying mistakes
-
Assuming cold brew is decaffeinated
Cold serving temperature tells you nothing about caffeine content. Grind states that its concentrate contains 101 mg of caffeine per 62 ml serving, while NHS guidance says caffeine can make you feel more awake.
If reducing caffeine before bed is the priority, choose an explicitly decaffeinated product and check the pack if you need a particular caffeine figure.
-
Choosing a latte by flavour name alone
M&S describes its Classic Latte as containing semi-skimmed milk and its separate oat latte as dairy-free. Those descriptions do not replace the ingredient and allergen information for the product in hand.
Check the current label for the specific version you intend to drink, particularly if you have an allergy or intolerance.
-
Expecting a decaf instant jar to contain cold brew
Instant granules and cold-brew concentrate require different preparation. A decaf instant jar may suit a late home-made iced coffee, but it is not a cold-steeped concentrate.
Choose by the preparation method you actually want, then follow the jar or concentrate’s directions.

Tesco
Tesco describes its Finest Unsweetened Cold Brew Coffee Concentrate, 500 ml, as extracted in cold water for several hours.

Grind
Grind describes its cold-brew concentrate as made by steeping 100% Arabica coffee in cold water.
- Grind gives a serving-level caffeine figure: 101 mg per 62 ml of its concentrate.

Sainsbury’s
Sainsbury’s lists iced-coffee products as well as decaffeinated instant coffees, including its Gold Roast Decaffeinated Instant Coffee Granules, 200 g.
- The decaf instant listing provides a jar-format alternative for making coffee at home.

Sandows
Sandows London says it makes cold-brew coffee in its London brewery.
- Its stated focus is cold-brew coffee.
- For a late-night drink, judge a particular product by its own caffeine and decaffeinated labelling.

Frequently asked questions
Is cold brew decaffeinated?
Not automatically: cold brew describes how coffee is prepared, not its decaffeinated status. Grind states that its concentrate contains 101 mg of caffeine per 62 ml serving. Look for an explicit decaf label if reducing caffeine is your late-night priority.
Should I buy concentrate or a ready-to-drink latte?
Choose concentrate if you want to control dilution and add your own ingredients; choose a ready-to-drink latte if you want a finished chilled serving. Tesco describes its cold brew as a concentrate, while M&S describes its latte as ready to enjoy from the fridge. Check caffeine and ingredients for the particular product either way.
Can I make iced coffee from a decaf instant jar?
Yes, if you want a decaf instant-coffee drink rather than cold brew. Prepare it according to the jar directions, then cool it or serve it over ice. Sainsbury’s lists decaffeinated instant granules among its coffee products.
How do I check whether a chilled latte contains milk?
Read the ingredients and allergen information for the exact drink. M&S describes its Classic Latte as made with semi-skimmed milk and its separate oat latte as dairy-free; the Food Standards Agency says allergen information must be provided for prepacked food and drink.
Is cold-brew coffee liqueur the same kind of drink?
No. A cold-brew coffee liqueur is an alcoholic product, not a direct substitute for a non-alcoholic coffee drink. Waitrose describes Tia Maria as a liqueur containing Jamaican rum, so check the product type rather than relying on the words “cold brew coffee”.
