Desk workers with no preparation time
A ready-to-drink cold coffee avoids measuring and mixing during a short break. Marks & Spencer describes its Classic Latte Cold Brew Coffee as ready to enjoy straight from the fridge.
Who is each format for?
People who can mix a drink at work
A concentrate is worth considering if you have a clean cup or bottle and water, milk or another suitable liquid. Check the preparation directions before relying on it for lunch.
Buyers checking milk and other ingredients
Choose by the exact pack, not the words “latte” or “cold brew”. Marks & Spencer describes its Classic Latte as containing semi-skimmed milk and its Oat Latte as dairy-free and made with oat milk; individual ingredient and allergen checks still matter.
What should you check before buying?
Start with the preparation you can manage at lunch, then check whether the product type, ingredients and pack directions match the drink you want.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation | Look for ready-to-drink wording or mixing directions. A concentrate needs a vessel and a liquid; an instant-coffee jar has its own preparation instructions. | I have only a short break and want to drink my coffee without measuring or washing a mixing cup. |
| Milk and allergens | Read the exact ingredients and allergen information. The Marks & Spencer Classic Latte contains semi-skimmed milk, while its Oat Latte is described as dairy-free. | If milk is unsuitable for me, I need to check the particular drink rather than assume every cold latte uses the same base. |
| Flavour and mixing | Check whether the product is unsweetened or flavoured, and what the directions say to add. Tesco lists an unsweetened cold-brew concentrate; Little's Creamy Caramel sachets are prepared with milk and ice. | I may want an unsweetened coffee, or I may prefer to choose the liquid I mix with a concentrate. |
| Product type | Distinguish cold-brew coffee from iced espresso concentrate and instant coffee; the container alone does not establish the brewing method. Check for an alcohol-by-volume statement when a search result is described as a liqueur. | I want a non-alcoholic desk coffee, and if I specifically want cold brew, I need the product description to identify it. |
Common buying mistakes
-
Treating a jar, concentrate and cold brew as the same thing
An instant-coffee jar may call for a different preparation method, while an iced espresso concentrate is not necessarily cold-brewed coffee.
Read the product type and preparation directions: choose a ready-to-drink format for no mixing, or a concentrate when you can make the drink yourself.
-
Choosing a latte by flavour name alone
Marks & Spencer describes its Classic Latte with semi-skimmed milk and its Oat Latte as dairy-free and oat-milk based. Those descriptions do not replace a check of the exact ingredients and allergens.
Check the pack each time you change product or variant, particularly if a particular ingredient is unsuitable for you.
-
Taking concentrate to a desk with nothing to mix it in
A concentrate still needs preparation. The directions for Little's Creamy Caramel sachets, for example, call for milk and ice.
Before buying, make sure you can obtain the required liquid and use a clean cup or bottle; otherwise, consider a ready-to-drink serving.
Bringing a mixing vessel and any required ingredients adds things to carry and clean up.
-
Mistaking cold-brew coffee liqueur for an ordinary coffee
Sainsbury's describes Tia Maria Cold Brew Coffee Liqueur as a cocktail product and lists it at 20% ABV. “Cold brew” in a name does not mean the drink is non-alcoholic.
For a non-alcoholic lunch drink, check the product name and alcohol-by-volume information.

Frequently asked questions
Do I need a jar for cold brew coffee at my desk?
No jar is needed for a ready-to-drink product: Marks & Spencer describes its Classic Latte Cold Brew Coffee as ready to enjoy from the fridge. A concentrate can also be mixed without a dedicated jar, but you will still need a clean cup or bottle and the liquid specified in its directions.
Is an instant-coffee jar the same as cold brew?
A jar does not establish how the coffee was made. Waitrose lists instant coffee separately from iced espresso concentrates; if you specifically want cold brew, check that the exact product is described as cold-brewed rather than choosing it by container.
What if I cannot use milk at work?
Consider a ready-to-drink product with a suitable stated milk base, or a concentrate you can mix with a suitable liquid. Marks & Spencer describes its Oat Latte as dairy-free, while its Classic Latte contains semi-skimmed milk; check the full ingredients and allergens on the exact product.
What should I check on a packaged coffee drink?
Check the food name, ingredients, allergens, quantity, date marking and any applicable storage directions on the exact pack. UK government food-labelling guidance identifies these as product information relevant to prepacked food, with storage instructions required where applicable.
Can a product called cold brew contain alcohol?
Yes. Sainsbury's lists Tia Maria Cold Brew Coffee Liqueur at 20% ABV and describes it for cocktails. For a non-alcoholic desk coffee, check the product name and alcohol-by-volume information rather than relying on “cold brew” alone.
