May 8, 2024, 12:56 PM

Australian engineers at the University of Queensland have developed an innovative ultrasonic cold brew coffee machine that significantly reduces the brewing time from the traditional 12 to 24 hours to under three minutes. This breakthrough, achieved using ultrasonic acoustic cavitation technology, allows for rapid preparation of cold brew coffee and introduces a new drink called 'cold espresso'. The technology has been highlighted for its potential to revolutionize the coffee-making process, offering a quick alternative to the lengthy traditional method.
