The Coffee Bean is a food item used in various Coffee recipes once ground.
The Coffee Bean is the prime ingredient in Coffee Dust, which is the base ingredient for almost all of the coffee flavors.
These beans can be found by breaking grass in the wild, same as Wheat seeds in regular Minecraft.
Once a bean is obtained, it can be planted in tilled soil. A fully grown coffee plant will have a brown bean shape on the end, though the plant will remain short.
