Sichuan Pixian Douban is a historic brand from Pidu District (formerly Pixian) in Sichuan Province, known for producing traditional doubanjiang made from fermented fava beans and chili peppers. Its production dates back to the 17th century, giving the brand an exceptional heritage and a strong connection to the local climate and microbial environment that shape the fermentation process.

The core of their method involves long, natural sun-fermentation, the use of the local Erjingtiao chili variety, and aging in clay vessels, resulting in a deeply layered, umami-rich flavor profile. The brand holds a protected geographical indication, ensuring that the paste originates directly from Pixian and follows traditional, region-specific techniques.

It is recognized for its thick texture, visible bean-and-chili structure, and a distinctive aroma that cannot be reproduced through industrial shortcuts. Because of its authenticity, Pixian douban is considered the benchmark for Sichuan cuisine and the foundation of classics such as Mapo tofu and twice-cooked pork.

Despite partial modernization of the industry, the brand continues to uphold original methods that preserve the unique character of natural fermentation. This combination of tradition, terroir, and craftsmanship makes Sichuan Pixian Douban one of China’s most respected and influential producers of doubanjiang.
