History of Menoka Tea Estate goes back to more than 100 years. The garden originally named Brahmputra Himalayan Tea Co. Ltd was developed by Britishers and in early 50's it was acquired by Late Pulin Krishna Roy, an eminent businessman from Bengal who renamed it 'Menoka' after the deity of temple within the tea estate. In 1958, soon after the Companies Act, 1956 was enacted, the estate was converted into a Private Limited Company, with Late Pulin Krishna Roy, founder, as its promoter and first Managing Director.

Located on the foothills of Himalayas in Assam near the Royal Kingdom of Bhutan, Menoka enjoys a lot of privileges unlike other tea gardens. The garden is conveniently located by the side of Indo Bhutan Border Road in district Baksa and well connected by both road and rail. The Guwahati Airport is located about 100 Kilometers from the estate. The nearest railway station Rangiya, is about 50 Kilometers from the estate.

The area under tea is spread over 318 hectares divided into 34 sections. The garden has included VERMI-COMPOSTING and HEAP-COMPOSTING towards the path of Organic Tea. Main varities are Chinese and Combodian, now uprooting and replanting with clones like P-126, S3A3, Tinali-17, TV 20 etc. There is a separate V.P.Nursery where about 100000 tea plants are produced annually to fulfill the garden's requirement for replanting and infilling.

The estate has a ISO 9001:2015 certified integrated modern tea manufacturing unit. The company follows a regular process of modernization and quality upgradation. The factory has a capacity to manufacture about 700000 kilograms of both Orthodox as well as CTC tea.

There are about 800 workers who are working in the garden for generations. They are from different cultures and come from all the four corners of the country. The garden has a hospital, school, clubs, crèches, playgrounds, temples churches, post office etc within its premises.
