The 45 Seconds That Define Coffee Roast Quality

When coffee lovers ask what really makes their cup taste the way it does, most don’t realize the answer happens in less than a minute — and not during brewing, but while the beans are still in the roaster. At a nondescript workshop near Beijing’s Lize Road and West Station South Plaza, a European Specialty Coffee Association member known as 'Uncle Bean' demonstrates how this critical phase unfolds. Surrounded by aspiring roasters, he explains how coffee changes in those decisive moments just after the first crack sounds.
