What does the process of "hand-picking" in coffee harvesting entail?

The process of "hand-picking" in coffee harvesting involves selecting only ripe coffee cherries. This method is crucial because coffee berries do not ripen all at once; they mature at different rates on the same tree. Hand-picking allows harvesters to selectively choose the cherries that are at their peak ripeness, which is essential for ensuring the best flavor and quality of the coffee beans. Ripe cherries typically have the highest sugar content and develop the most complex flavors, which directly affects the coffee's overall quality.

In contrast, selecting only unripe cherries would not yield high-quality coffee, as these cherries lack the desired sweetness and flavor profile. Using machines to gather coffee cherries can result in unripe and overripe cherries being harvested together, which can diminish the quality of the final product. Lastly, choosing the largest cherries does not necessarily correlate with the ripeness or flavor profile, as size does not guarantee optimal quality. Thus, selecting ripe cherries through hand-picking is a key practice for producing high-quality coffee.
