The cocoa plant blooms in the third year and begins to produce from the fifth-sixth.
A cocoa tree produces an average of 30-50 pods, which gives a maximum of 1 kg of dry seeds. To make the seeds ready for consumption, you make them undergo one fermentation for 8-10 days, followed by one drying it's a squeezing, during which the fat is separated from the seeds.
