Green coffee beans are simply regular, unroasted coffee beans that remain completely raw. These coffee beans have a higher chlorogenic acid content which is probably thought to have numerous health benefits. It acts as an antioxidant.
Their extract is widely popular as a nutritional supplement but, like roasted coffee, green coffee can also be bought in whole-bean form and used to make a hot drink.
Keep in mind that a mug of this light green drink won’t taste like the roasted coffee you’re used to, because it has a much milder flavor. It is said to taste more like herbal tea than coffee.
