Are coffee beans actually a type of bean?

No, coffee beans are not beans they are actually seeds. The coffee bean comes from the coffee plant. It is the seed of the plant. A bean is a kind of seed in the fabaceae family. The coffee plant doesn't belong to the fabaceae family because the coffee plant is in the rubiaceae family, so the coffee bean is not a bean.  All in all this paragraph has taught you that the next time you want to annoy someone at a coffee shop say can I have a coffee with coffee beans? - John Baskin
