About This Coffee

Established in 2023 by Lu Sun, No Stone Estate is a pioneering force in the Yunnan coffee industry. The company believes that high-quality coffee can only be consistently produced through scientific management of the entire coffee production process, combined with modern technology and advanced techniques. No Stone Estate is dedicated to sourcing top-quality coffee beans from various regions of Yunnan and is deeply involved in every aspect of the coffee supply chain, from field management to the selection of green coffee beans.

In the production areas, No Stone Estate provides producers with professional technical guidance that covers all aspects of coffee cultivation, including variety selection, field maintenance, plot analysis, fresh fruit harvesting, and processing methods, always aiming for the highest quality standards.

The company makes significant investments in green bean processing and storage management. Using state-of-the-art coffee bean processing equipment, No Stone Estate carefully hulls, sorts, and refines different coffee varieties using diverse post-processing methods to produce superior green coffee beans. They implement zoned storage, strictly controlling warehouse temperature and humidity to maintain optimal moisture content and water activity levels in the beans, thereby reducing the risk of deterioration. Beans processed by different methods are stored separately to avoid cross-contamination and external interference with flavor. Regular sampling and testing of raw materials and finished products ensure the stability and quality of the coffee beans.

No Stone Estate not only offers customers a diverse selection of high-quality coffee beans but is also committed to providing customised products for those with specific needs. The company collaborates with customers to create personalised experiences, inviting them to participate in the coffee fields and join coffee farmers in processing their custom coffee.

Enzymatic Process

Similar to how in yeast Innoculated coffees, sterilised coffee cherries are paired with a selected, specific yeast to catalyse the fermentation; in this particular process, enzymes are selectively paired instead.

For this particular coffee, Lu Sun, proprietor of No Stone Estate extracted enzymes from Sarcodactylis  (Sometimes referred to as Buddha's hand, a member of the citron family). Once extracted, the enzymes are added to water to dilute them and then fermented aerobically for 8 days.

During the honey processing, this enzymatic mixture is added to break down the mucilage and sealed to ferment anaerobically for 150 hours. The resultant aromatic produced by this enzymatic breakdown is a delicate floral akin to lilies. This is then washed and cleaned. Once cleaned, the coffee is dried down to the desired moisture content and sealed for shipment.
