A “Gaiwan” is a traditional Chinese tea brewing cup, popularly used in tea houses in China. A Gaiwan consists of a cup with a lid and a saucer. This is a classic white, porcelain Gaiwan with a set of 4 cups and has a capacity of 120ml / 4.1oz. It’s the perfect brewing cup for Green and White teas, and also for Oolong and Pu-erh teas. The steep slope of the lid and fine edge around the rim offers good control and makes this Gaiwan easy to use.
