As one of America's coffee capitals, Portland, Oregon, has grounds for worry: coffee prices have soared to historic highs. Christopher Hendon, a College of Arts and Sciences chemistry professor at the University of Oregon, studies the global industry and said the tariffs cost independent coffee operators more than consumers. "[The consumer is] probably not feeling it," Hendon told CBS News. "You might not care today, because the price didn't change all that much, but you might care if your local café disappears."
