Dark tea, also known as Hei Cha, is a type of tea made from the leaves of the Camellia sinensis plant, undergoing a unique fermentation process that imparts a rich, complex flavor. Originating from China, particularly in the provinces of Hunan, Sichuan, and Yunnan, dark tea has a long history and cultural significance.

Known for its deep, earthy taste and smooth finish, dark tea is often aged to enhance its flavor, developing notes of malt, chocolate, and sometimes even a hint of smokiness. The aging process, combined with fermentation, gives dark tea its distinctive characteristics and health benefits.
