Chill Coffee Beans to Brew Tastier Beverage, Say Researchers

Brewing more flavorsome coffee could be as simple as chilling the coffee beans before grinding, say scientists. Image credit: Shixugang.
Jun 15, 2016 by News Staff

An international team of researchers has found that chilling roasted coffee beans before grinding results in narrower distribution of small particles, which during the brewing process allows access to more flavor from the same amount of coffee. Brewing more flavorsome coffee could be as simple as chilling the coffee beans before grinding, say scientists. Image credit: Shixugang. The research team, led by Dr. Christopher Hendon from the University...

This image of the continental United States at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012. The image was made possible by the satellite's ‘day-night band’ of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires and reflected moonlight.
