Qianjie-brief introduction of SL28 raisin solarization in Las Lajas Manor, Costa Rica

Francisca and Oscar Chac ó n are the third generation operators of Las Lajas. Las Lajas is located in the foothills of Sabanilla de Alajuela Po á s Volcano in the Central Valley. The Chac ó n family has been growing coffee since their grandparents for more than 80 years. When Oscar's father died of cancer in 1995, they suspected that the chemical fertilizers and pesticides used on the farm were the culprits. They no longer used toxic chemicals and required all processes to be planted and fertilized in accordance with organic standards. use organic compost, while extending organic standards to soil, shade trees and washing plant procedures, using ecologically friendly natural farming methods and shade planting in native forests.

After five years of organic cultivation, until the soil, leaves, and fruit analysis are qualified, in 2000, Lajas became the first organic certified manor in Costa rica, and the Lajas manor has passed the Japanese JAS, American USDA and NOP organic certification. After passing the organic certification, the couple went a step further and began to set up their own treatment plant. In the past, they could only send cherries from the farm to large commercial processing plants, but the post-processing process could not be controlled. Some washing plants handled their own coffee, and the overall quality was greatly improved.

Innovative tanning method-raisin sun (Raisin): combine black pearl and black soul, the whole process of shade drying for more than three weeks. First of all, it was laid flat on the cement floor in the greenhouse, piled into a hill in the afternoon, covered with plastic cloth for shade, and then spread flat the next morning. About a week or two later, it was changed to the shade of the African scaffolding under the greenhouse. There are two sets of the upper and lower layers of this African shelf. Every day, the upper and lower cycle changes the position, which will make the coffee beans dry evenly until the end of processing, so that the fermentation cycle is higher. The sweetness and flavor complexity of coffee beans are greatly improved.
