Coffee is made by roasting, grinding and brewing coffee beans. Coffee beans are the fruits of coffee trees, and coffee fruits are also called coffee fruits, because ripe coffee fruits are very similar to ripe cherries. Usually there are two coffee beans in each coffee cherry, and only one in a small amount.

Hot cocoa is actually hot chocolate, but we usually add milk, sugar and other raw materials to the chocolate we buy in the market to flavor it to reduce the strong bitterness of cocoa. This is why the purer the chocolate, the more bitter it is. But cocoa beans are roasted and ground. Cocoa beans are the seeds of cocoa fruits. There will be many cocoa beans in a cocoa nut, and the cocoa nut is also very big.

So cocoa and coffee are completely different things. Don't confuse them.
