Where does the idea of male and female coffee beans come from? An analysis of the formation characteristics and flavor myths of PB round beans

People often say that traveling to Indonesia brought back rare "male beans" coffee, which is expensive and supposedly especially delicious. But are coffee beans really divided into male and female?

Is the distinction between male and female coffee beans real? An analysis of the concept, causes, and price differences of PB round beans

Many friends who are just getting into coffee have heard the terms "male bean" and "female bean," and some even think coffee trees are divided into male and female. In fact, coffee flowers are hermaphroditic plants, and coffee beans themselves have no gender distinction.
