Coffee : The fruit
Coffee fruit is a type of stone fruit that’s produced by the coffee plant.
It’s often referred to by other names, including coffee cherry or coffee berry.
The fruit is typically small and green, turning a deep red or purple shade as it ripens. The coffee bean is housed inside of the fruit and technically classified as a seed.
During coffee production, the coffee beans are extracted, while the fruit is typically discarded.
However, because of emerging research on its potential health effects, coffee fruit is now gaining traction as a popular supplement and beverage ingredient.
