Researchers at UNSW Sydney have harnessed the power of ultrasonic sound waves to make espresso-strength coffee with room temperature water, cutting energy use by up to 75%.
“Because the process produces a concentrated, espresso-strength coffee, it can be used directly to manufacture ready-to-drink products, or shipped as a concentrate and later diluted into a range of drinks, including cold brew and milk-based coffee drinks.”
Okay, that makes sense. A more energy-efficient way to mass-produce cold drinks and concentrates.
There’s no way the average coffee drinker would be happy with a room-temperature shot of espresso. Yuck!
