Is a coffee beans berry?

No, coffee beans are not berries. Coffee beans are the seeds of a fruit called a coffee cherry, which is a drupe. A drupe is a type of fruit that has a fleshy outer layer and a hard inner pit, such as a peach or a plum. The coffee cherry has a thin outer skin, a fleshy pulp layer, and two coffee beans inside the pit. The coffee beans are the seeds of the coffee cherry and are what are used to make coffee.
