Green coffee is a type of coffee that hasn't been roasted yet. Think of it like a plain chocolate chip cookie dough that hasn't been baked yet. The coffee beans are like the cookie dough and the roasting process is like the baking process for cookies.
Green coffee has a greenish color because it hasn't been exposed to high heat, which is what happens during the roasting process. When coffee beans are roasted, they change color, become darker and take on different flavors.
Green coffee has a different flavor than roasted coffee. It can be more bitter and have a grassy taste. Some people like it because it has a unique flavor and can be healthier because it has more antioxidants.
If you want to make green coffee into a drink, you can grind the beans and steep them in hot water like you would with tea. But be careful, the caffeine content is higher in green coffee because it hasn't been roasted, so it could make you feel extra energetic or jittery.
So, in summary, green coffee is like a plain cookie dough without the baking process. It has a different flavor and can be prepared like tea but may contain more caffeine.
