Abstract
This essay examines the process by which tea, a plant and product introduced into the Indian subcontinent in the early 19th century as a colonial cash crop, became indigenized and popularized as chai, often regarded today as India’s ‘national drink’. This process mainly occurred during the 20th century and involved aggressive and innovative marketing by both British and Indian commercial interests, advances in the technology of processing Assam tea, and changes in social space and practice, especially in urban areas.
