What is the coffee harvest season?

The concept of a 'coffee harvest season' is often misunderstood as a singular, global event. In reality, coffee production is a decentralized, year-round cycle dictated by local microclimates. Farmers and producers manage harvest windows based on the physiological needs of the coffee tree, which is highly sensitive to rainfall and temperature. In regions near the equator, such as parts of Colombia or Kenya, trees may flower twice annually, resulting in a primary harvest and a secondary 'fly crop.' Conversely, in regions with distinct wet and dry seasons, the harvest is concentrated into a single, intense period. Altitude acts as a critical moderator; higher-elevation farms experience cooler temperatures, which slows the maturation of the coffee cherry, often delaying the harvest by several weeks or months compared to lower-altitude neighbors. This extended ripening period is prized by producers and roasters alike, as it allows for greater sugar development and density in the bean. A common misconception is that coffee is 'seasonal' in the same way as produce like berries; while fresh arrivals are seasonal, the global supply chain ensures that coffee is being picked, processed, and dried in some part of the world every month. Producers must navigate these shifting windows, often complicated by climate volatility, which can delay maturation or cause irregular flowering, forcing farmers to adapt their labor and processing schedules in real-time.
