Coffee bean picking process, growth process, year flavor description, taste, variety origin.

Selective picking, that is, walking between trees several times at intervals of 8-10 days and picking only those ripe red berries, higher quality coffee beans are used.

Advantages: the picked coffee fruit is uniform in size, similar in maturity and free of other impurities, which is beneficial to post-processing.

Disadvantages: high cost

There are two ways to prepare coffee beans for the baking process. The method chosen has a significant impact on the final value and quality of coffee. The cheapest method of processing is called "drying", which is used for lower-grade coffee beans, while higher-quality coffee beans are processed by "wet treatment". Drying is used for unwashed coffee beans. Wet treatment is used for thoroughly washed or semi-washed coffee beans. Except for the more common use of drying in Brazil and Ethiopia, most Arabica coffee beans are processed by wet treatment. Some robastian coffee beans are also processed by wet treatment.

Drying is also known as sun-drying or non-washing: the drying method is relatively simple. First of all, spread the freshly picked fruit on the exposure field for a week or two until the fruit crackles and dries naturally. After that, the dried pulp, endocarp and silver peel are removed by a sheller.

Advantages: the fruity aroma of coffee beans can be well preserved and the price is low.

Disadvantages: coffee beans may be contaminated with the fishy smell of the ground, and the quality of coffee beans is uneven.

Note: this method is mostly used for lower-grade coffee beans and is still widely used in Brazil, Ethiopia, Congo, Indonesia, Yemen and other places.

The washing method is also called wet treatment: after the outer pulp of the coffee fruit is removed by the pulp separator within 12 hours after the coffee is picked, the coffee beans are soaked in a large cement tank filled with water to separate the fruit. The coffee beans are then pasted in the fermentation box for about 12-36 hours, containing 15% water after fermentation, and the fermented coffee beans are washed clean with clean water. The coffee beans are dried in a dryer or dried in the sun, and the coffee beans are called "parchment coffee beans", waiting for export.
