Ultrasonic espresso method could cut café costs
Key Questions
What is ultrasonic espresso and how does it work?
Ultrasonic espresso is a new method developed by UNSW researchers that uses room-temperature water and sound waves instead of heat and pressure. It produces coffee comparable to traditional espresso while using significantly less energy.
How much energy could ultrasonic espresso save for cafes?
The method has the potential to cut energy use by up to 75% compared to conventional espresso machines. This could lead to lower operating costs for cafes if the technology scales successfully.
Is ultrasonic espresso ready for home use or cafes?
The research is still in early stages and not yet practical for home brewers. Further work is needed on scalability, equipment, and detailed flavor comparisons before widespread adoption.
New research from UNSW on ultrasonic espresso using room-temp water and sound waves—potential for significant energy savings (75% less energy). Blind test indistinguishable from traditional espresso. Not yet actionable for home brewers but a developing story worth monitoring for scalability and flavor comparison. First seen today.
