Assam tea is a black tea named after the region of its production, Assam, in India. It is also traditionally used in Yunnan province in China. Assam tea is manufactured specifically from the plant Camellia sinensis var. assamica (Masters). This tea, most of which is grown at or near sea level, is known for its body, briskness, malty flavour, and strong, bright colour. Assam teas, or blends containing Assam, are often sold as "breakfast" teas. For instance, Irish breakfast tea, a maltier and stronger breakfast tea, consists of small-sized Assam tea leaves.
Darjeeling tea is a tea from the Darjeeling district in West Bengal, India. It is available in black, green, white and oolong. When properly brewed, it yields a thin-bodied, light-coloured infusion with a floral aroma. The flavour can include a tinge of astringent tanniccharacteristics and a musky spiciness sometimes described as "muscatel".
Unlike most Indian teas, Darjeeling tea is normally made from the small-leaved Chinese variety of Camellia sinensis var. sinensis, rather than the large-leaved Assam plant (C. sinensis var. assamica). Traditionally, Darjeeling tea is made as black tea; however, Darjeeling oolong and green teas are becoming more commonly produced and easier to find, and a growing number of estates are also producing white teas. After the enactment of Geographical Indications of Goods (Registration & Protection Act, 1999) in 2003, Darjeeling tea became the first Indian product to receive a GI tag, in 2004–05 through the Indian Patent Office.
