Cold brew may be the hottest trend in coffee-making, but not a lot is known about how this process alters the drink`s chemical characteristics. Scientists now report that the content of potentially health-promoting antioxidants in coffee brewed without heat can significantly differ from a cup of joe prepared with the same beans in the traditional way, particularly for dark roasts.
