Harvest Season
Also known as: coffee harvest, picking season, new crop
The coffee harvest season represents the culmination of a biological cycle beginning with anthesis (flowering), triggered by significant rainfall following a period of dormancy. For Coffea arabica , the duration from blossom to physiological maturity typically spans seven to nine months, while Coffea canephora (Robusta) requires nine to eleven months. Geographically, harvest cycles are dictated by the movement of the Intertropical Convergence Zone (ITCZ), which influences precipitation patterns.

Definition
<p>The coffee harvest season represents the culmination of a biological cycle beginning with anthesis (flowering), triggered by significant rainfall following a period of dormancy. For <i>Coffea arabica</i>, the duration from blossom to physiological maturity typically spans seven to nine months, while <i>Coffea canephora</i> (Robusta) requires nine to eleven months. Geographically, harvest cycles are dictated by the movement of the Intertropical Convergence Zone (ITCZ), which influences precipitation patterns. In Northern Hemisphere regions such as Ethiopia, Guatemala, and Vietnam, the primary harvest occurs between October and March. Southern Hemisphere producers, notably Brazil and Peru, harvest from May to September. Equatorial regions, including Colombia and Kenya, often experience two distinct flowering periods, resulting in a primary harvest (main crop) and a secondary harvest known as the 'fly crop' or <i>mitaca</i> in Colombia.</p><h3>Harvest Methods and Ripeness</h3><p>Precision during this period is vital; harvesting under-ripe (green) or over-ripe (black/raisin) cherries introduces chemical defects. Selective hand-picking, common in specialty production, involves workers manually selecting only cherries with a Brix sugar concentration typically ranging from 18% to 25%. Conversely, strip picking and mechanical harvesting—prevalent in the flat Cerrado regions of Brazil—collect all cherries simultaneously, requiring post-harvest electronic color sorting to remove defects. The following table compares primary harvesting methods:</p><table><thead><tr><th>Method</th><th>Labor Intensity</th><th>Ripeness Uniformity</th><th>Common Origins</th></tr></thead><tbody><tr><td>Selective Picking</td><td>High (3-5 passes)</td><td>Superior</td><td>Ethiopia, Colombia, Central America</td></tr><tr><td>Strip Picking</td><td>Moderate</td><td>Low (requires sorting)</td><td>Brazil, Vietnam</td></tr><tr><td>Mechanical Harvesting</td><td>Low</td><td>Low (requires sorting)</td><td>Brazil (Cerrado), Australia</td></tr></tbody></table>
Why It Matters
<p>Harvest timing directly dictates the sensory profile and chemical stability of the green coffee bean. Freshly harvested 'new crop' coffee exhibits peak enzymatic activity, resulting in higher concentrations of organic acids—such as citric, malic, and phosphoric acids—which contribute to the bright, complex acidity prized in specialty grading. As coffee ages beyond six to twelve months (becoming 'past crop'), lipid oxidation and the degradation of volatile aromatic compounds lead to the development of 'baggy' or woody taints, characterized by a loss of enzymatic clarity and the emergence of guiacol-like notes.</p><p>For roasters and importers, understanding these cycles is critical for inventory management and ensuring peak flavor vibrancy. The seasonal nature of coffee means that a roaster must transition between origins to maintain freshness; for example, shifting from fresh Central American arrivals in May to fresh East African or Southern Hemisphere arrivals in November. Furthermore, the timing of the Brazilian harvest—the world's largest producer—significantly impacts global supply dynamics and Intercontinental Exchange (ICE) futures pricing. Weather anomalies during the harvest window, such as the July-August frost (geada) risks in Brazil, can trigger extreme market volatility, affecting the C-price and subsequent specialty premiums globally.</p>
Frequently Asked Questions
What is a fly crop or mitaca?
A fly crop, known as mitaca in Colombia, is a secondary harvest that occurs outside the main harvest window. This phenomenon is common in equatorial countries where two distinct rainy seasons trigger two flowering periods per year. While often smaller in volume, the fly crop provides consistent cash flow for farmers and maintains supply for exporters throughout the year.
How does altitude affect the harvest date?
Higher altitudes correlate with lower average temperatures, which slows the metabolism of the coffee plant and the maturation rate of the fruit. In regions like Nariño, Colombia, or Huehuetenango, Guatemala, coffee grown above 1,800 meters may be harvested two to four months later than lower-altitude crops, often resulting in higher bean density and concentrated sugars.
What defines 'new crop' versus 'past crop' coffee?
New crop refers to coffee within six to nine months of its harvest date, retaining optimal moisture (10-12%) and vibrant acidity. Past crop refers to coffee from the previous year's cycle. As green coffee ages, it undergoes lipid oxidation and moisture loss, leading to a flatter taste profile and muted aromatics.
Why do some countries have a single harvest while others have two?
The number of harvests is determined by the latitude and the resulting rainfall patterns. Regions farther from the equator have distinct wet and dry seasons, leading to one flowering and one harvest. Equatorial regions experience the passage of the Intertropical Convergence Zone twice a year, leading to two rainy seasons and two distinct harvest cycles.

Coffee Varieties
Arabica Coffee Varieties: Origin, Flavor & Genetics
Arabica is known for its complex, aromatic, and nuanced flavor. It generally has higher acidity, lighter body, and more aromatic complexity than Robusta. Notes range from floral and citrus (highland African) to chocolate and caramel (Central and South American). Sweetness is generally high, with clean, balanced cups being the hallmark of quality Arabica.
RobustaRobusta Coffee: Flavor, Caffeine & Growing Regions
Bold, strong, and earthy. Known for heavy body, low acidity, and notes of dark chocolate, nuts, and grain. Can exhibit earthy, woody, or rubbery notes in lower-quality lots. Fine Robusta (carefully processed) can produce a cleaner, sweeter cup with chocolate and caramel notes.

Acidity
In coffee tasting, acidity refers to the bright, vibrant, and often fruity quality that gives coffee its liveliness and structure. Unlike the negative connotation of acidity in everyday language, coffee acidity is a desirable characteristic when balanced. It is perceived as a pleasant tartness or brightness on the palate, similar to the acidity in wine or fruit.
Origins & GeographyAltitude
Altitude is the elevation at which coffee is grown, measured in meters above sea level. Higher altitude generally produces denser, more complex, and more acidic coffee. Arabica is typically grown at 800 to 2,000 meters, while Robusta at 0 to 800 meters.
Origins & GeographyCoffea Arabica: The Specialty Coffee Species Explained
Arabica coffee (Coffea arabica) is a species of coffee plant native to the highland forests of Ethiopia and South Sudan. It is the most widely cultivated coffee species worldwide, accounting for approximately 60 to 70 percent of global coffee production. Arabica is prized for its complex flavor, refined acidity, and aromatic diversity, producing notes ranging from floral and citrus to chocolate and caramel depending on origin, variety, and processing.
Origins & GeographyCoffea Robusta: The Hard-Body Coffee Species Explained
Robusta coffee (Coffea canephora) is the second most cultivated coffee species after Arabica, accounting for approximately 30 to 40 percent of global coffee production. Native to sub-Saharan Africa, Robusta is hardier, more disease resistant, and grows at lower elevations than Arabica. It contains roughly twice the caffeine of Arabica and produces a heavier body, lower acidity, and more bitter cup profile.
Origins & GeographyCoffee Cherry
The coffee cherry is the fruit of the coffee plant, a small round drupe that ripens from green to red (or sometimes yellow or orange) when ready for harvest. Each cherry typically contains two coffee seeds (beans) arranged face to face, though occasional single-seed cherries produce what are known as peaberries. The cherry consists of skin (exocarp), pulp (mesocarp), mucilage, parchment (endocarp), silver skin, and the seed itself.
Origins & GeographyEthiopian Coffee: The Birthplace of Arabica Coffee
Ethiopia is widely considered the birthplace of coffee, where the Coffea arabica plant originated in the highland forests of the southwest. Ethiopia remains one of the world's top coffee producers, known for extraordinary genetic diversity, distinctive regional cup profiles, and processing traditions that date back centuries. Regions like Yirgacheffe, Sidamo, Guji, and Harrar produce some of the most sought-after specialty coffees in the world, prized for their floral, citrus, and tea-like characteristics.
