When properly brewed, it yields a thin-bodied, light-coloured infusion with a floral aroma. The flavour can include a tinge of astringent tannic characteristics 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,
Camellia sinensis there is no high-quality evidence that tea confers significant benefits. In clinical research over the early 21st century, tea has been studied extensively for its potential to lower the risk of human diseases, but none of this research is conclusive as of 2017. Caffeine is a molecule produced in "Camellia sinensis" and functions as a secondary metabolite. Caffeine is a purine alkaloid and its biosynthesis occurs in young tea leaves and is regulated by several enzymes. The biosynthetic pathway in "C. sinensis" differs from other caffeine producing plants such as coffee or guyausa. Analysis of the pathway was carried out
