The traditional method relies on hot water—precisely heated to between 195 and 205 degrees Fahrenheit—to extract the rich flavors, oils, and caffeine from finely ground coffee beans. However, a groundbreaking innovation from researchers at the University of New South Wales (UNSW) in Australia is challenging this long-held belief. Led by Colombian researcher Francisco Trujillo, the team has developed a method to brew espresso using <strong>ultrasonic waves</strong> instead of hot water, a process they call <strong>&ldquo;ultrasonic espresso.&rdquo;</strong></p>
