 Rather than roast and brew coffee for drinking, the Haya sun-dry the beans and chew on them.Coffee beans are often provide for guests visiting the homestead and, traditionally, they are left as offerings to ancestors at shrines and, in the past, were used to seal blood-pacts by splitting a single bean in half, cutting one's navel, smearing blood onto the half-bean, and placing the bean in the other participant's mouth.The shortage of cattle manure and other types of agricultural fertilizer has greatly impacted banana production among the Haya.
