As coffee enthusiasts, it’s our privilege to celebrate this journey, fostering a deeper connection with every delightful cup we enjoy.
What are green coffee beans?
Green coffee beans are simply raw coffee beans that have not been roasted. They are the seeds of the Coffea plant, which produce coffee cherries. After the cherries are harvested, the beans are extracted, cleaned, and dried, but they remain in their unroasted state. This is the form in which coffee beans are sold for making specialty brews or for use in health products.
These beans are prized for their potential health benefits and unique flavors that develop after roasting. In their natural state, green coffee beans have a different profile compared to roasted beans, featuring more acidity and less bitterness. They are often used in dietary supplements due to the presence of chlorogenic acids, which are believed to have various health benefits.
