What is coffee flowering?

Coffee flowering is the stage when coffee trees produce their small, white blossoms - intensely fragrant, jasmine-scented, and brief. Pollinated flowers develop into coffee cherries over the following seven to nine months; unpollinated ones drop without producing fruit.

In Arabica, flowering is triggered by rainfall following a dry period - what farmers call flowering rain. In origins with a pronounced dry season this produces synchronised flowering across a region, leading to a concentrated harvest window. In equatorial climates like Colombia, flowering is more continuous, which is why two annual harvests are possible.

The flowering season matters to buyers because it's the first predictor of what the next harvest will look like. Strong, even flowering after good dry-season conditions suggests a reliable crop ahead. Erratic or sparse flowering is often the first signal that availability and quality may be below expectations - useful context when you're planning forward contracts months before harvest.
