Plant form and farm choices
The Coffee Tree
Coffee trees differ more than the casual observer might expect. Leaves vary across varieties, growth habits change from one cultivar to another, and those botanical differences often correspond to differences in the cup. Some varieties are prized for sweetness, others for structure or mouthfeel, and still others for the practical virtues they offer in the field.
This last point is essential. Producers do not usually choose a variety only because it tastes good. Yield, resistance to disease, suitability to local climate, and the financial stability of the farm weigh just as heavily, and often more so. It is therefore a mistake to romanticize variety choice as though it were only an artistic decision. On most farms it is also an economic calculation, and sometimes a question of survival.
Nursery and investment
From Seed to Tree
Most serious farms begin in the nursery. Seeds are planted in rich soil, where they germinate and push upward until the developing shoot lifts the bean above the ground. At this stage growers often call the seedling a soldier, because it looks as though a coffee bean has been balanced on top of a thin green stem. Shortly afterwards, the bean opens and the first leaves appear.
Coffee grows quickly enough in its first year that young plants can often be moved from the nursery into production after six to twelve months. Yet this should not be mistaken for a fast crop. A farmer may wait around three years before a newly planted tree fruits properly, which means that every planting decision commits land, labour, and capital long before the farm sees a meaningful return. For that reason, entering coffee production is serious business, and leaving it is equally consequential.
Flowering and ripening
Blossom and Fruit
Most coffee trees produce one principal harvest each year, though some regions also see a second and usually smaller crop. The cycle often begins after a prolonged period of rainfall, which triggers flowering and covers the trees in fragrant white blossom with a scent many compare to jasmine.
Insects such as bees assist pollination, but Arabica has an important advantage: it can self-pollinate. Unless the flowers are damaged by weather or other disturbance, they will usually set fruit. From there, the process slows dramatically. Coffee cherries may take up to nine months to ripen, and they do not do so evenly. That uneven ripening is one of coffee's earliest quality problems, because the producer must choose between harvesting quickly with mixed maturity or paying for multiple passes so that each cherry is taken closer to its perfect moment.
