Yixing Zisha teapots are often called the “ultimate tea brewing tool” because of their unique clay materials. Different types of clay vary in porosity, mineral composition, and firing density, which directly affect the taste of brewed tea.
Many beginners focus only on shape and overlook clay quality, often ending up with a teapot that does not perform well.
This guide explains the 7 most mainstream Yixing Zisha clay types to help you choose correctly.
