Tannin extract comes from gallnuts, which contain approximately 50-60% tannin and has a lovely tea-like aroma. Gallnuts are produced as a plant excretion generated when irritants are released by the larvae of gall insects, such as the gall wasp. Gallnuts are a native product of China and Southeast Asia, but are also produced in small amounts in Turkey, India, Japan, and Korea.
