What is the difference between picking, stripping, and mechanical harvesting?

Picking selects individual ripe cherries by hand — highest quality. Stripping strips all cherries from a branch at once — faster, but includes unripe ones. Mechanical harvesting shakes the entire tree.

Why that matters

The three harvesting methods differ fundamentally in effort, cost, and quality outcome.

Picking (selective hand-harvesting) is the most labour-intensive method. Pickers walk through the rows and take only cherries that have reached the right ripeness — bright red, plump, no discolouration. They return three to five times per season. An experienced picker harvests 50–100 kg of cherries per day. After processing and roasting, that leaves only 10–20 kg of roasted coffee. The labour cost per kilogram is enormous, which is why picking-harvested coffee is more expensive.

Stripping is faster. One hand grasps the branch, the other strips all cherries off in a single motion — ripe, unripe, and overripe together. Sorting happens afterwards, often by flotation in water tanks (ripe cherries are denser and sink). Despite subsequent sorting, more unripe cherries enter the processing, which can negatively affect flavour: green, grassy notes, missing sweetness.

Mechanical harvesting uses shaking machines that vibrate the coffee tree and drop the cherries onto collection tarps. This only works on flat, level plantations — steep highlands in Colombia or Ethiopia are ruled out. The method is cost-efficient for mass production but qualitatively the weakest of the three options.

The harvesting method sets the quality ceiling. No roaster, however skilled, can make good coffee from beans harvested unripe. That’s why specialty coffee always begins at the harvest.

At Green Wall Coffee

At our café on Sophienstraße 27 in Berlin-Lichtenberg, we pay attention to the harvesting method when selecting our coffees. The bags rarely say “picking” explicitly, but the origin farms and cooperatives our roasters work with harvest exclusively by selective picking. That’s part of the quality promise that defines specialty coffee.
