Coffee culture in the UK has been evolving over the years and now, in 2024, even more people are gravitating towards the rich, smooth, and low-acidic taste of cold brew coffee. The process of making cold brew coffee is more of an art than a science, with different variables that can significantly impact the end result. Whether you’re a novice looking to experiment with cold brew at home, or a seasoned barista seeking to refine your technique, this comprehensive guide will provide you with the key steps and tips you need to brew the perfect cold brew coffee.
Choosing the Best Beans for Cold Brew
It all begins with the coffee beans. The type of beans you choose can significantly impact the flavour of your cold brew coffee. The best beans for cold brew are typically those with a medium to dark roast. These beans often have a robust flavour profile that can withstand the long brewing process.

When it comes to the origin of the beans, it’s often a matter of personal preference. However, beans from regions like Brazil, Colombia, and Ethiopia are often recommended due to their unique flavour profiles that are well-suited for cold brewing.
Remember, the freshness of the beans also matters. Try to use beans that have been roasted within the last two weeks to ensure you get the most flavour out of them.

The Grind: Coarse or Fine?
The grind of your beans will play a significant role in determining the taste of your cold brew. For cold brew, a coarse ground is typically recommended. This is because the coffee will be in contact with the water for a long period, and a coarse grind will prevent over-extraction, which can lead to a bitter taste.
While most electric grinders will have a setting for a cold brew grind, a manual burr grinder can also do the trick. Burr grinders are often preferred because they produce a consistent grind size. The right grind will ensure that your cold brew is smooth and full-flavoured.
The Water: Filtered or Tap?
The water you use for your cold brew can also impact its taste. Tap water often contains minerals and chemicals that can interfere with the taste of your coffee. Therefore, it’s best to use filtered or spring water when making your cold brew.
Water temperature is another factor to consider. Cold brew, as the name suggests, is brewed with cold water. However, using room temperature water is also acceptable. The key is to ensure that the water is not warm or hot, as this could lead to over-extraction.
The Brewing Process: Time and Ratio
The brewing process is where the magic happens. Cold brew coffee is steeped for a long period, typically between 12-24 hours. The exact brewing time will depend on your taste preference. A longer brew time will result in a stronger, more concentrated coffee, while shorter brewing times will produce a milder flavour.
The ratio of coffee to water is another important factor. A general rule of thumb is to use a 1:4 or 1:5 coffee-to-water ratio. However, this ratio can be adjusted based on personal preference.
Filter and Serve: The Final Steps
After the brewing process is complete, you will need to separate the coffee grounds from the liquid. The best way to do this is by using a fine mesh strainer lined with a coffee filter. Be sure to let the coffee filter through naturally – don’t try to rush the process by pressing or squeezing the grounds.
The resulting cold brew concentrate can be served in a number of ways. Some people prefer to dilute it with water or milk, while others enjoy it straight for a more intense coffee experience.
Regardless of how you choose to serve your cold brew, the final product should be a smooth, rich coffee with low acidity and a naturally sweet taste. With the right techniques, making cold brew coffee at home can be a simple and rewarding experience. Now all that’s left is for you to start experimenting with your own cold brew techniques. Enjoy the process and the delicious results!
Using the Right Equipment: A Matter of Convenience and Quality
The equipment you use for brewing your cold brew coffee can also affect the quality and taste of your final product. Some prefer to use a mason jar or a French press, while others might opt for a specialised cold brew coffee maker.
A Mason jar is a versatile and cost-effective option that most people already have in their kitchen. To make cold brew coffee with a Mason jar, simply add your coarse ground coffee to the jar, pour in cold water, stir, and let it steep. After the brewing process, you can filter the coffee using a cheesecloth or a fine mesh strainer.
On the other hand, a French press, although typically used for hot coffee, can also be a great tool for brewing cold brew coffee. Its built-in filter makes the process easier as it eliminates the need for a separate straining process.
For those willing to invest a little more, specialised cold brew coffee makers are available in the market. These devices often come with a built-in filter and airtight seal to keep your cold brew fresh for longer, providing convenience for regular cold brew drinkers.
Regardless of the equipment used, ensuring it is clean and free of any residual coffee from previous brewing is integral. The remaining residues can interfere with the taste of your new batch of cold brew, making it taste stale or off.
Storing Your Cold Brew: Keeping It Fresh
How you store your cold brew coffee after brewing is as important as how you brew it. The best way to store cold brew coffee is in the fridge. The cold temperature will help preserve the coffee’s flavour and freshness.
Cold brew coffee can be stored in the fridge for up to two weeks without losing much of its flavour. This makes cold brew a convenient option for those who want to have coffee ready to go at any time.
Remember to store your cold brew in a sealed container, such as a glass bottle or mason jar, to prevent it from absorbing the flavours of other items in your fridge.
Conclusion: Master the Art of Cold Brewing
Cold brewing is a unique coffee brewing method that requires patience and a little bit of experimentation. From selecting the right coffee beans and grind size, to choosing the water type and brewing time, every decision you make can impact the flavour profile of your cold brew coffee.
But with the right techniques, you can make a delicious cup of cold brew that is smooth, less acidic, and uniquely flavourful. So whether you’re a seasoned coffee connoisseur or a novice enthusiast, don’t be afraid to experiment and tweak the process until you find your perfect brew.
Remember, the joy of cold brewing lies not only in the final product but also in the process itself. So, take the time to savour each step – from the aroma of the freshly ground beans to the satisfaction of the first sip. Enjoy your journey of making the best cold brew coffee in the comfort of your own home!
