Is there caffeine in cocoa bean?

Yes, cocoa beans contain caffeine, but in much smaller amounts than coffee beans.

* Cocoa beans: Contain about 0.2% caffeine by weight.

* Coffee beans: Contain about 1.5% caffeine by weight.

This means a typical cup of hot chocolate will have about 5-10mg of caffeine, compared to a cup of coffee which can have 80-100mg or more.
