We do not use any petroleum powered machines in any of the processes. We use horses to carry the natural fertilizers to the mountains and the harvested beans are carried by the workers in “bultos” to the cafeteria processing building. We use electric motors with natural lubricants to remove the husks before soaking and fermentation. It is very important throughout the processing phases to keep the odors and vapors of other plants or machines from contaminating the delicate nature of the product.
