Yunnan Province represents a dynamic and emerging specialty coffee region in southwestern China. Known for its diverse microclimates and high-altitude growing conditions, the area provides ideal terroir for cultivating exceptional coffee. The region’s unique combination of elevation, volcanic soils, and moderate temperatures creates an environment that nurtures complex and distinctive coffee profiles.

Founded in 2023 by Lu Sun, No Stone Estate is a forward-thinking coffee company dedicated to scientific coffee production. Their approach combines cutting-edge technology with meticulous agricultural practices, offering comprehensive support to local producers. From varietal selection to advanced processing techniques, the estate is committed to elevating the quality and reputation of Yunnan’s coffee industry.

No Stone Estate employs an innovative honey processing method enhanced by enzymatic co-fermentation. Local Buddha’s hand citrus is fermented with water for eight days to develop optimal Brix and pH levels. This enzymatic solution is then combined with Catimor coffee cherries for an extended 150-hour anaerobic fermentation, creating a unique flavor development process that distinguishes this microlot.
