Green coffee beans are unroasted coffee beans that are harvested from the coffee plant. Unlike roasted coffee beans, they have a green color and a mild, grassy flavor. Green coffee beans contain higher levels of chlorogenic acid, a compound that is believed to have potential health benefits. They are often used for making green coffee extract or roasted at home to create personalized coffee blends. Green coffee beans are sought after by those looking for a different coffee experience or exploring the potential health effects of the unroasted beans.
