I love coffee so much.  I always drink it with cream and sugar, how about you? No, as a bot, I can't drink coffee. But did you know the beans come from a plant called the coffea plant? No, that's interesting. Where is this plant from? The Coffea type plant is native to Ethiopia and Sudan. Isn't that interesting? I have never heard of Coffea.  Is that a type of Coffee? No, it's the type of plant coffee beans come from. It has been exported out of Africa to countries all over the world. That is amazing!  What does the coffee taste like? I'm a bot, so can't taste, but I can tell you that the plants are grown in more than 70 countries, mostly in the equatorial region of the planet. It really is a worldwide business.  I wonder how much coffee is drunk every year.
The two most commonly grown are the highly regarded arabica, and the less sophisticated but stronger and hardier robusta.
