In coffee harvesting, what characteristic is crucial for selecting cherries?

The selection of coffee cherries during harvesting is primarily determined by color. Ripe coffee cherries typically exhibit a vibrant red hue, indicating that they have reached optimal maturity and sweetness, which is critical for achieving high-quality coffee. This characteristic is essential because unripe cherries, which may be green or yellow, often contain higher acidity and lower sugar content, leading to a less desirable cup of coffee. Hence, color is a direct indicator of ripeness in coffee cherries and ultimately affects the flavor profile of the brewed coffee.

Size, weight, and shape can vary significantly among cherries, even when they are ripe. While these characteristics might play a role in sorting or grading the cherries post-harvest, they do not take precedence over color when it comes to the initial selection of cherries that are ready for picking. Selecting cherries based on color ensures that only the best and most flavorful cherries are harvested, aligning with quality standards in coffee production.
