Purple Clay Coffee Press

Purple clay, a unique material originating from Yixing, China, has been used to craft teapots since the Ming Dynasty. Its special texture, characterized by numerous micro-pores and a high content of rare earth elements, allows it to emit far-infrared rays. This unique property enhances the brewing process, resulting in a more flavorful and aromatic cup of tea. The same principles can be applied to coffee brewing, promising a superior coffee experience.

A Shenzhen-based company sought an OEM experienced in purple clay production. They contacted us to produce this unique purple clay coffee plunger for the premium market of Starbucks Reserve.
