4. Harvesting and Processing Coffee Beans

Harvesting and Processing Coffee Beans

Harvesting

• Coffee beans are ready to harvest when they are ripe. Ripe coffee beans are typically red or purple in color. You can also check the beans for ripeness by gently squeezing them. Ripe beans will be slightly soft to the touch.

• To harvest coffee beans, simply pick them off the tree by hand. Be careful not to damage the branches of the tree.

Processing

• After harvesting, the coffee beans need to be processed to remove the pulp and seeds. There are two main methods of processing coffee beans: the wet method and the dry method.

• The wet method is the most common method of processing coffee beans. In this method, the coffee beans are pulped to remove the skin and pulp. The beans are then fermented for a period of time, which helps to develop their flavor.

• The dry method is a less common method of processing coffee beans. In this method, the coffee beans are simply dried in the sun. The dry method produces a more earthy flavor than the wet method.

Storing

• Once the coffee beans have been processed, they need to be stored in a cool, dry place. Coffee beans can be stored in an airtight container for up to two years.

Determining Ripeness

Determining Ripeness

• Color: The color of the coffee cherries is one of the most obvious indicators of ripeness. Ripe coffee cherries are typically red or purple in color. However, some varieties of coffee beans may be yellow or orange when ripe.

• Size and shape: Ripe coffee cherries are also typically larger and rounder than unripe cherries. Unripe cherries may be green or yellow in color and may be more elongated in shape.

• Feel: Ripe coffee cherries should be slightly soft to the touch. Unripe cherries will be hard and firm.

• Taste: If you are unsure whether or not a coffee cherry is ripe, you can try tasting it. Ripe coffee cherries will have a sweet and slightly acidic taste. Unripe cherries will be more tart and bitter.

Harvesting Techniques

Harvesting Techniques

Handpicking

• Handpicking is the most common method of harvesting coffee beans. In this method, workers carefully pick the ripe coffee cherries from the tree by hand.

• Handpicking is a labor-intensive process, but it allows for the most selective harvesting. This method is often used for high-quality coffee beans.

Mechanical harvesting

• Mechanical harvesting is a faster and less expensive method of harvesting coffee beans. In this method, a machine is used to shake the tree and collect the ripe coffee cherries.

• Mechanical harvesting is less selective than handpicking, and it can damage the tree and the coffee cherries. This method is often used for lower-quality coffee beans.

Processing and Storing

Processing and Storing

Drying

• After harvesting, the coffee cherries need to be dried to remove the moisture content. This can be done by spreading the cherries out in the sun or using a mechanical dryer.

• Drying the coffee cherries helps to preserve their flavor and aroma.

Roasting

• Roasting is the process of heating the coffee beans to develop their flavor and aroma. The roasting process can be varied to produce different flavors and intensities of coffee.

• Coffee beans can be roasted in a variety of ways, including using a home roaster, a commercial roaster, or even a pan on the stovetop.

Storing

• Roasted coffee beans should be stored in a cool, dry place. Coffee beans can be stored in an airtight container for up to two years.
