When temperatures rise, many coffee lovers start looking for something colder, smoother, and more refreshing than a traditional hot coffee.
That is where cold brew comes in.
Cold brew coffee has become increasingly popular because of its naturally smooth flavour, lower bitterness, and refreshing finish. Best of all, it is surprisingly simple to make at home without expensive equipment.
Whether you are completely new to cold brew or looking to improve your recipe this summer, this guide covers everything you need to know.
What Is Cold Brew Coffee?
Cold brew coffee is made by steeping coffee grounds in cold water for an extended period, usually between 12 and 24 hours.
Unlike iced coffee, which is brewed hot and cooled down afterwards, cold brew is never exposed to heat during extraction.
This slower brewing process creates a coffee that is:
- Smoother
- Less acidic
- Naturally sweeter
- Refreshing over ice
Many people who find traditional coffee too bitter enjoy the softer flavour profile of cold brew.
What Coffee Works Best for Cold Brew?
Cold brew works particularly well with coffees that have chocolatey, nutty, caramel, or naturally sweet tasting notes.
Medium and darker roasts are especially popular because they create a fuller-bodied and smoother cold brew.
Freshly roasted coffee makes a huge difference, helping preserve sweetness and aroma even when served cold.

Cold Brew Coffee Recipe
One of the best things about cold brew is how simple it is.
You only need:
- Coarsely ground coffee
- Cold filtered water
- A large jar or container
- A filter or fine sieve
Simple Cold Brew Recipe
- 100g coarsely ground coffee
- 1 litre cold water
Step-by-Step Method
- Add the coffee grounds to a large container or jar.
- Pour over the cold water slowly.
- Stir gently to ensure all grounds are saturated.
- Cover and leave in the fridge or at room temperature for 12 to 18 hours.
- Strain using a paper filter, fine mesh sieve, or cafetière.
- Serve over ice.
The result is a smooth, refreshing coffee concentrate that can be enjoyed black or with milk.
Use Coarse Ground Coffee
Grind size matters when making cold brew.
A coarse grind works best because it slows extraction and helps prevent bitterness or cloudy coffee.
If the grind is too fine, the coffee can become muddy and overly strong.
Many specialty coffee roasters can grind coffee specifically for cold brew if requested.

Cold Brew vs Iced Coffee
Cold brew and iced coffee are often confused, but they taste very different.
| Cold Brew | Iced Coffee |
|---|---|
| Steeped in cold water | Brewed hot then cooled |
| Smooth and low acidity | Brighter and sharper flavour |
| Long extraction time | Quick preparation |
| Often naturally sweeter | Can taste more acidic |
Both are refreshing in summer, but cold brew is usually smoother and easier drinking.
Ways to Serve Cold Brew
Cold brew is incredibly versatile and easy to customise.
Popular serving ideas include:
- Over ice
- With milk or oat milk
- With vanilla syrup
- With tonic water
- Blended into iced lattes
You can also dilute stronger cold brew concentrate with water depending on your preferred strength.
How Long Does Cold Brew Last?
Cold brew can usually be stored in the fridge for around 5 to 7 days.
Keeping it sealed in an airtight container helps preserve freshness and flavour.
Many people make larger batches during warmer weather for easy iced coffee throughout the week.
Why Cold Brew Is Perfect for Summer
Cold brew coffee is refreshing without losing the rich flavour coffee lovers enjoy.
Its smoother profile also makes it popular among people who find hot coffee too intense during warmer months.
Because it can be prepared in advance, cold brew is also convenient for busy mornings, outdoor gatherings, or afternoons in the garden.
