Williamson Magor & Company Ltd. was established in the year 1868 as a tea company, The group now produces an output of 30 million Kg of tea per year from its 23 tea estates in Assam and 5 million Kg from its 5 tea estates in Dooars.

The Williamson Magor story began in 1868 when two young and enterprising Englishmen, James Hay Williamson and Richard Manuel Blamey Magor, got together at the Great Eastern Hotel In Calcutta and signed a partnership deed in April 1869. Over the following few decades, while remaining almost exclusively in the hands of the Williamson and Magor families, the company consolidated its position, expanding through mergers. Running the tea estates was left to the visiting agent, and the partners generally came to India only in winter, for a couple of months, for a leisurely trip around Assam.

The group has grown in size and experience. Today their gardens stretch from the foothills of the Himalayas to the banks of the Brahamputra, producing that magic brew, tea. More importantly, it has grown to become the world's largest producer of tea, having 28 tea estates with an output of 35 million Kgs of tea per year. The group's reliability and efficiency as a supplier of bulk tea has helped increase tea exports steadily up to 15% per year for the past few years. 

With an average fine leaf count targeted at over 75% on a 7 day round, the WM Group is aimed at achieving consistency in quality. From the handling of leaf to its transportation their systems and processes cater to preserve the leaf quality on its way to the factory.

The group is well established in the bulk tea selling network, both at home and overseas. They have installed state-of-the-art machinery and have centralised research facilities to enhance yield and quality.

As consumer tastes become more sophisticated, the group is on course at satisfying this demand and adding value to its products and has successfully launched three brands of packet tea - Tez, Premium Gold and Jaago.
