A new study suggests that chilling the coffee beans before grinding would make a flavorful cup of coffee.
More than 80% of American adults are coffee drinkers. With the beverage's increasing popularity, coffee connoisseurs are on a constant quest for the most perfectly brewed coffee. While the grind is considered as one of the most important elements of the brewing process, recent findings by researchers Maxwell Colonna-Dashwood and Christopher Hendon revealed that brewing a more flavorful cup of coffee simply requires cooling the beans prior to grinding.
"The research suggests that temperature of bean needs to be more constant to help us achieve consistent grinds. It suggests that cooler temperatures will allow us to maximize surface area and utilize more of the coffee," the researchers said, Eureka Alert reported.
Published in the journal Scientific Reports, the scientists looked into how temperature impacts grinding ranging from normal room temperature to -196 degrees Celsius. The researchers found out that chilled coffee beans have greater post-grind consistency with smaller and more uniform particles. As a result, the brewer can produce a stronger flavor in less time with fewer grains.
"It will alter the taste, because subtle changes in particle size distributions make a huge difference in rate of extraction. I wouldn't be surprised if people struggled to achieve balanced extractions," said researcher Christopher Hendon as quoted by UPI.
To achieve a more consistent grind, the researchers advised to keep the coffee beans' temperature constant. In addition, they hope that their study can lead to further development of new grinding technology that would one day influence industry-wide method of preparing coffee.
"We anticipate these results will influence the production of coffee industrially, as well as contribute to how we store and use coffee daily," the researchers wrote in their study as quoted by Tech Times.
