Coffee connoisseurs have long held the belief that adding a little water to the beans before grinding them could make a difference. A new study by researchers at the University of Oregon seems to confirm exactly why. “When you grind coffee, it goes everywhere,” said study coauthor Christopher Hendon, an associate professor of computational materials chemistry at the University of Oregon. When using a cafetiere, French press or AeroPress, nothing much changes because, given the coarser grind required with these, “all of the water is already touching all of the coffee,” Hendon said. “I found that the amount of water needed for the purported benefits varied wildly from grinder to grinder,” he added.
