“Peaberry” coffee beans (commonly called male beans) are a unique type of coffee bean that develop as a single oval-shaped seed inside the coffee cherry. This usually happens due to unusual pollination, drought, or other environmental factors, causing only one of the two seeds that normally grow in a cherry to fully develop.
