Tie Guan Yin is a type of oolong tea originating from China, specifically in the Fujian Province. Its name translates to "Iron Goddess of Mercy" in English. The tea leaves are semi-fermented, resulting in a unique flavor profile that is floral, fruity, and slightly smoky with a slightly sweet aftertaste. It is known for its health benefits, such as reducing inflammation, improving digestion, and boosting the immune system. Tie Guan Yin tea is brewed using hot water and can be enjoyed hot or cold.
