Scientists Transform Espresso Machine into Quick Cold Brewer Using Sound Waves

Are you tired of waiting hours or even days for your cold brew coffee to be ready? Well, researchers in Australia have found a solution to this problem by transforming a home espresso machine into a sonic reactor that can produce cold brew in just minutes.

The team at UNSW Sydney has developed a method that uses sound waves to hasten the extraction of coffee brews, resulting in a quick and efficient cold brew process. This breakthrough has the potential to revolutionize the cold brewing industry, making it easier and faster for both home and commercial use.

By retrofitting a Breville BES920 dual-boiler espresso machine with an integrated circuit and ultrasonic reactor, the researchers were able to create a system that can brew cold coffee at ambient water temperatures in a matter of minutes. The sonic waves generated by the machine help intensify the extraction of aroma and flavors from the coffee grounds, resulting in a rich and flavorful cold brew.

In sensory analysis tests, the researchers found that the sonicated cold brew samples were comparable to a 24-hour cold brew in terms of flavor and texture. This means that coffee shops and restaurants can now produce high-quality cold brew on demand without the need for extensive refrigeration space or large brewing units.

This innovative technology opens up new possibilities for the coffee industry, allowing for quick and efficient cold brew production that meets the demands of consumers. With this new method, enjoying a delicious cold brew coffee at home or in a cafe is now easier and more convenient than ever before.
