Called the "champagne of teas," Darjeeling tea was the first product to get the Geographical Indication (GI) tag in India in October 2004. Known for its unique aroma and taste, the tea takes its name from Darjeeling, the eponymous town and region, where the first bushes were planted in the early 1800s as an experiment with the Chinese variety. According to the Tea Board of India, only the tea grown at an elevation ranging from 600 to 2000 metres above sea level in 87 identified gardens (in Darjeeling and Kalimpong districts of West Bengal), qualifies as "Darjeeling Tea." Some of the estates now offer tea tourism, including a stay, a visit to the garden and factory, tea tasting, and other interesting activities.
