The Indian tea plant is native to north east India, and was brewed and consumed much before the Britishers established it as a commercial industry. The variety in Assam, which is one of the largest tea producing regions of the world is called Camellia Sinensis and the variety is called Assamica. It is cultivated in the valley of the Brahmaputra river. The leaves of the Assam tea bush are dark green and glossy and fairly wide compared to those of the Chinese tea plant. Assam tea has a rich, deep-amber color and is known for its brisk, strong and malty character.
