Assam produces some of the finest and most expensive teas in the world. Other than the Chinese tea variety Camellia sinensis, Assam is the only region in the world that has its own variety of tea, called Camellia assamica. Assam tea is grown at elevations near sea level, giving it a malty sweetness and an earthy flavor, as opposed to the more floral aroma of highland (e.g. Darjeeling , Taiwanese) teas.
