Audio waves having more uses than making beats has been in the news a great deal as of late. Thus, the idea that they can also be used to make a cup of coffee really shouldn’t be that surprising at all.
That’s exactly the case when it comes to Australia’s Elixir Specialty Coffee, which uses a pre-step process called “ultrasonic-assisted extraction” that applies low heat to coffee beans using ultrasonic sound waves. More specifically, the process destroys the cell walls of coffee beans and diffuses caffeine and other flavors through the water.
LA Weekly states that the coffee “looks like whiskey and taste like a watered-down cold brew.” The drink is currently sold at Los Angeles’ Copa Vida Coffee, and is sold in capped jars labeled with both the coffee’s country of origin and the number of hours that the drink was processed.
