If it hadn't been for the honey treatment of Costa Rican coffee, Qianjie probably didn't know that coffee beans need to be processed and eventually become raw beans before they can be exported. What's more, I don't know that there are very professional terms for the treatment of coffee: washing, tanning, honey treatment and so on. No way, coffee in China is still a niche market, after rapid development, but it is not the main choice!

Colombian people say that coffee has changed the country, can enjoy a rich environment, coffee is indeed an outstanding contribution. Today, the Costa Rican coffee industry is one of the well-organized industries in the world, with a yield of 1700 kg per hectare. Costa Rica has a population of only 3.5 million, while there are 400 million coffee trees, and coffee exports account for 25 per cent of the country's total exports. The volcanic soil of Costa Rica is very fertile and well drained.

Central valley

1200-1600 meters above sea level, the production season from November to March, this production area has three sub-production areas, they are San Jose, Eredia, Alajuela.

There are three high-altitude volcanoes in the producing area: Irazu, Barva and Poas, which provide rich nutrients for the surrounding coffee producing areas. The excellent micro-climate and the two volcanic fertile soils of Po á s and Barva make the beans in this area have superior characteristics, such as chocolate cocoa flavor, bright acidity and elegant aroma.

The Central Valley is also the first area to grow coffee in Costa Rica, and then to other regions to develop the country's coffee industry, moderate rainfall, an average annual temperature of 19 ℃, coupled with high altitude, so the bean hard aroma, smooth, high acidity, full-bodied, rich aroma, coffee in this area is the earliest coffee growing area in Costa Rica, rich in volcanic soil, sometimes with chocolate flavor. The front section is washed and the back section is dried by machine at low temperature.

Costa Rica is the first country to use coffee raw soybean honey treatment. There are three major coffee producing areas in Costa Rica, namely, Tarazu, the central valley and the western valley.

Located in the central valley area at the foot of the Po á s de Alajuela volcano, Ras La Haas Manor has been operated by the owner Chac ó n family for more than 80 years. The estate is 1300m above sea level and has an annual output of about 46000 jin. During the annual production season of La Lajas Manor from December to February, the owner insists on harvesting only ripe and red fruits, and most of them use dense treatment and sun drying to enhance the sweetness and mellowness of the coffee, and at the same time, it is placed in the African shelf-type sunburn field to ensure that the coffee can evenly receive the sun and avoid excessive fermentation. At the same time, the manor has also actively obtained international organic certification, which has been certified by USDA of the United States, JAS of Japan and NOP of Japan.

Finca Las Lajas is located in Costa Rica's famous coffee producing area [Central Valley Central Valley], which belongs to the Paos volcanic mountains. Due to the local fertile soil and rich mineral content, it creates good conditions for high-quality coffee. The estate's reputation comes not only from its excellent coffee quality, but also from its insistence on organic ecological farming. Organic farming has been introduced since 1990 and became the first organically certified coffee farm in Costa Rica in 2000.

At present, it has been certified by three international organic organizations, namely USDA, JAS and NOP. Oscar Chacon, the third-generation manor operator, said that in addition to the great challenges in agricultural technology in promoting organic certification, what is even more serious is the economic pressure brought about by the sharp decline in production. In the third year of promotion, the annual output of the manor is even only 20%. All this does not affect the determination to promote organics. staying away from chemical fertilizers and pesticides can not only protect the sustainable development of the environment, but also take care of the health of coffee farmers.

"innovative tanning treatment-Black Soul"

The raw bean treatment of La La Haas Manor comprehensively adopts honey treatment and sun treatment, and develops characteristics different from other manors, in which honey treatment is divided into yellow honey, red honey and black honey according to the amount of pectin retained, and the sun is divided into two products: Pearl Negra and Alma Negra according to the degree of fermentation. Black pearl belongs to the flavor of strong fruit fermentation, and the black soul is partial to the tonality of sun-dried molasses. It is the most fashionable way to bask in the sun today, but it is two different amorous feelings!

The bean of Black Soul is treated in the sun.

The harvested red coffee fruits are placed on the African scaffolding in the early morning, and the whole process takes about three weeks to turn and expose regularly for one day and rest with plastic cloth until the moisture content is 11.5%.

04 | Analysis of raw beans

The varieties of black soul beans are Kaddura and Kaduai, which are common in American beans.

Kaddura, a natural variety of bourbon, was discovered in Brazil in 1937. Its tree is not as tall and shorter as bourbon. Due to inheriting the blood of bourbon, the resistance is relatively weak, but the yield is higher than that of bourbon. Although found in Brazil, Kaddura is not suitable for growing in Brazil, so it is not planted on a large scale in Brazil, but is popular in Central and South America, such as Colombia, Costa Rica and Nicaragua.

Kaduai is an artificial hybrid of Kaddura and Mondu Novo. Kaduai has a good ability to resist natural disasters, especially wind and rain. Kaduai tree species are relatively low, compared with other coffee trees, the fruit of Kaduai is stronger and harder to pick, and the fruit is both red and yellow.

[black soul] raw beans are typical sun-treated yellowish green, smelling like a faint sour Hawthorn.

05 | Baking analysis

Roaster Yangjia 800N semi-direct fire (baking capacity 300g)

The furnace temperature is preheated to 170 ℃ into the pot, and the firepower is turned on to 140 after opening the throttle for 30 seconds. When the temperature is 101.6 ℃, the firepower remains unchanged, and the throttle turns yellow when the temperature is 101.6 ℃. The smell of grass disappears, enters the dehydration stage, the firepower remains unchanged, and the throttle remains 4.
