Most coffee growing countries have a season. Ethiopia picks from roughly October through January. Brazil's harvest runs from May into September. Guatemala and much of Central America pick from December through March. Once the cherries are in, the trees rest, flower, and set fruit for the next year, and there is nothing to harvest for months.
Colombia does not work that way. Colombian farms harvest twice a year, a main crop and a smaller secondary crop, and in some regions of the country coffee is being picked in nearly every month of the calendar. That is unusual, it is the result of geography rather than clever farming, and it has a surprising amount to do with why Colombian coffee is so reliably available and so consistently good.

Coffee Trees Follow The Rain
A coffee tree flowers in response to rain. After a dry period, the first significant rainfall triggers a flush of white, jasmine scented blossoms across the tree. Those flowers are pollinated, drop their petals within days, and leave behind tiny green fruit that will take roughly seven to nine months to ripen into red cherries ready for picking.
In a country with one wet season and one dry season, this produces one flowering and one harvest. The trees bloom when the rains arrive, the cherries develop through the growing months, and the harvest happens after the dry season returns. The whole cycle takes about a year and repeats.
Colombia sits almost directly on the equator, and the parts of the country where coffee grows have a different rain pattern. Instead of one wet season, most of the coffee regions get two, one roughly from March to May and another from September to November. Two wet seasons mean two flowerings, and two flowerings mean two harvests.
The Main Crop And The Mitaca
Colombians call the smaller harvest the mitaca, sometimes translated as the fly crop or the traviesa. The main crop, the cosecha principal, is the larger of the two and typically accounts for around 60 to 70 percent of a farm's annual production. The mitaca picks up the rest.
Which harvest is the main one depends on where you are in the country. Colombia is long from north to south, and the rain pattern shifts as you move along the Andes. In the northern regions, like parts of Santander and the north of Antioquia, the main harvest tends to fall in the last months of the year. In the southern departments, like Nariño, Huila, and Cauca, the main harvest often comes in the first half of the year, with the mitaca in the second half. The central coffee axis, around Caldas, Quindío, and Risaralda, sits in between and often sees a more balanced split.
The practical result is that at almost any point in the year, some part of Colombia is in harvest. A roaster who wants fresh crop Colombian coffee can find it in March and can find it again in October, from different regions, with different characteristics.
Why This Matters For Freshness
Green coffee does not last forever. After harvest and processing, a coffee is at its best for roughly six to twelve months, depending on storage. After that, the bright acidity and distinct origin character begin to fade, and the coffee drifts toward a flat, papery, generic profile that roasters describe as past crop.
For a single harvest origin, this creates a rhythm. Fresh crop arrives at roasteries a few months after picking, tastes great for a stretch, and then slowly ages until the next crop lands. Roasters manage this by buying carefully and timing their releases, but there is always a period near the end of the year where the available lots are older than anyone would like.
Colombia's double harvest smooths that curve. Because a new crop is coming from somewhere in the country every six months, a roaster can keep fresh Colombian coffee on the menu year round without stretching a single lot across twelve months. This is one of the reasons Colombian coffee has become the backbone of so many blends and so many house coffees. It is not just that it tastes good. It is that it tastes good in February and in August, from lots that were picked recently.
What Two Harvests Ask Of The Farmer
The double harvest is a gift for freshness, but it is a demand on the farm. A tree that flowers twice a year is being asked to produce twice a year, and it needs to be fed, pruned, and managed to sustain that. Colombian farms tend to be small, often family run plots of a few hectares, and the year is a continuous cycle of picking, processing, and preparing for the next flowering.
Because the harvest never fully stops, there is also rarely a long rest period for the trees, the drying patios, or the people. A farm in Huila might be finishing the mitaca in one part of the property while the main crop cherries are still ripening in another. Labor has to be available in more months of the year than on a single harvest farm, and picking is done by hand, one ripe cherry at a time, because cherries on the same branch ripen at different rates.
The upside for quality is that Colombian pickers are practiced at selective picking. A branch might be visited multiple times over several weeks, with only the ripe red cherries taken each pass. That selectivity is a large part of why Colombian coffee has such a consistent, clean, sweet profile, and it is a skill that the double harvest keeps sharp.

Kenya Has A Fly Crop Too
Colombia gets most of the attention for its two harvests, but it is not entirely alone. Kenya sits on the equator as well, with a similar two rainy season pattern, and Kenyan farms also have a main crop and a smaller fly crop. The Kenyan main harvest runs roughly from October to December, with the fly crop from around May to July.
The Kenyan fly crop is generally smaller and less celebrated than the main crop, and some roasters skip it entirely. But the underlying mechanism is the same: equatorial geography with bimodal rainfall produces two flowerings, and two flowerings produce two harvests. It is a pattern that belongs to a narrow band of the world, and Colombia happens to have the largest and most organized coffee industry sitting inside that band.
How The Two Crops Taste
Roasters who buy both Colombian harvests sometimes notice differences between them, though the differences are subtle and vary by region and year. The main crop, coming from the larger flowering, often has slightly more consistency across lots because there is more coffee to select from. The mitaca, being smaller, can produce some exceptional microlots precisely because farmers have more time to give each batch attention, but it can also be more variable.
Weather during ripening matters more than which harvest it is. A dry, sunny ripening period tends to concentrate sugars and produce sweeter, denser cherries. A wet ripening period can dilute flavor and increase the risk of defects. Because the two crops ripen in different weather windows, they can taste noticeably different from the same farm in the same year.
For the drinker, the practical takeaway is that Colombian coffee is not one flavor. A washed Huila from the main crop and a washed Nariño from the mitaca are both Colombian, both clean and sweet, but they can differ in acidity, body, and fruit character in ways that reward paying attention to the region and harvest on the bag.
What The Roaster Does With It
A roaster's job with Colombian coffee is not to make it taste like something else. It is to preserve what the double harvest and the careful picking already put into the bean: a clean, balanced sweetness, a medium body, and an acidity that is present without being sharp.
That preservation is easier when the roast is even. Colombian coffees are generally dense, high grown beans that can take heat well, but they are also prone to a flat, muted profile if the roast is rushed or scorched. Air roasting suits them because every bean is suspended in the same hot air and develops on the same schedule, with no contact scorching and no chaff burning into the batch. The caramel and red fruit sweetness that a good Colombian carries comes through with clarity instead of being buried under smoke.
When you drink a Colombian that tastes clean and sweet and specific, you are tasting the rain pattern that gave it two flowerings, the hands that picked only the ripe cherries, and a roast that did not get in the way.
Why It Is Always On The Shelf
The next time you notice that Colombian coffee is always available, that it is on the menu at nearly every cafe and in the lineup of nearly every roaster, understand that this is not only a marketing decision. It is geography. A country that harvests twice a year, in staggered regions, can supply fresh coffee in a way that single harvest origins physically cannot.
That reliability is part of what makes Colombian coffee a safe choice. It is also part of why it is worth taking seriously rather than treating as a default. Two harvests a year, picked by hand, from a country that has spent a century learning how to grow this crop well, is not a small thing to have in your cup.
