How to make cold brew coffee in the office

Cold brew coffee is the hottest new trend in the coffee world. It’s refreshing, delicious and surprisingly easy to make. It’s different from iced coffee which we’ll talk more about, but if you’d like to understand a bit more about cold brew coffee read on.

What’s the difference between iced coffee and cold brew?

You’d be forgiven for thinking these two drinks are similar, but they’re made very differently. Cold brew is as the name suggests, is brewed without heat. This lowers the coffee’s acidity and creates a smoother, but stronger flavour.

Iced coffee starts off how you would usually make your coffee using hot water. It’s often brewed at double strength and then left to cool down. Iced coffee can be made in a number of different ways, such as from a coffee machine, cafetiere, filter coffee, or even using instant coffee. Serve it with milk, add sugar or sweetener to taste, and then pour over ice.

Cold brew dates back to the 1600s in Japan and through trade and travel, cold-brewing made its way around the world. Over more recent years, it’s been increasing in popularity and you can find it in most high street coffee shops.

Cold brew takes a lot longer to make than iced coffee but it’s still very simple to do and we promise, it’s worth the wait. You can make it at home or at work – whatever is best for you.


To start you’ll need to get some quality ground coffee. We recommend using around 50g of ground coffee to 400ml of cold water. First, add your ground coffee to a large jug or pitcher if you want to make enough for the office. Then you just want to pour over cold water, but don’t stir it at this stage. It’s best to use filtered water for a cleaner, more refreshing taste, so if you have an undercounter water tap at work, use this over normal tap water.

You’ll want to steep it in the fridge or you can leave it out on the counter for between 12 and 24 hours. Once you’ve steeped it and you’re happy with the time you’ve left it, you can then gently mix it together. Once mixed, you’ll now need to filter it. You can filter it using a sieve with coffee filter paper over it, or you can layer up some kitchen towels. You’re basically just draining all the coffee grounds so the coffee drink is smooth. Pour into another jug or large jar and place it in the fridge. And that’s it, once cold, it’s ready to serve.

To serve dilute 1 part of cold brew with 2 parts of still or sparkling water (or to your taste) and serve with lots of ice. You can keep it in the fridge and it will last for around 2 or 3 days for you to enjoy. Of course, if you don’t fancy making cold brew, you can also pick up ready-made versions in shops and supermarkets. You can get it in individual-sized cans ready to drink or purchase cold brew concentrate syrup that you simply add water and ice to serve.
