Coffee aficionados often swear by a 1:5 coffee-to-water ratio for the quintessential cold brew. This gives a harmonious brew that's ready to sip as is. Yet, if you're in the mood for a blend, an equal mix with cold water, milk, or any cold brew concoction of your choosing works wonders. Looking to add a touch of sweetness? Consider integrating sweetened milk or a drizzle of liquid sugar.

It's always wise to start with foundational knowledge and then venture into experimentation. Embark on your cold brew journey with the 1:5 ratio, refine it based on your preferences, and then branch out. For a little insider tip, Todd from Le Colombe Coffee whispers of his own unique brew secrets.

Mastering the Cold Brew Concentrate Ratio

Creating your cold brew concentrate at home is not only a journey towards achieving the perfect flavor but also a smart way to save money and time.

A "Light Sip" is perfect for those who prefer a mellow, less intense cold brew. The "Bold Experience" suits those craving a robust, full-bodied flavor, while the "Morning Creamy Indulgence" offers a rich and velvety start to your day, thanks to the cream.

Why Ratios Matter

When it comes to cold brew coffee understanding goes beyond just grasping the basic concept or following generally recommended coffee to water ratios. Coffee itself is an experience, unique for each individual. Some people may enjoy the boldness of a brew while others may prefer a delicate sip. We acknowledge this range of preferences.

It's important to acknowledge that finding the balance between cold water and coffee is crucial for achieving that perfect cup tailored to your personal taste.

Not fully grasping the significance of the coffee to water ratio can result in disappointment preventing you from experiencing the delight of brew.

Additionally it's essential to consider the shelf life of brew. Typically when stored in the refrigerator cold brew remains fresh for a week. This knowledge can help you plan ahead by brewing the amount you anticipate consuming within that time period. If you have a gathering or expect consumption in the coming week you can adjust your brewing quantity accordingly.


Equipped with these insights into brew ratios you're now ready to embark on your brewing journey. We're excited to hear about your experience with your brew! Remember, although the process might initially seem intricate it becomes second nature with understanding and practice.
