A Journey Through Time: The History of Tea Farming

The history of tea farming is a rich tapestry woven over millennia, with its roots firmly planted in ancient China. Legend has it that Emperor Shen Nung discovered tea in 2737 BCE when tea leaves accidentally blew into his boiling water. While the exact origins are shrouded in myth, archaeological evidence suggests tea consumption in China dates back thousands of years.

Initially, tea was primarily used for medicinal purposes. Over time, its recreational consumption grew, and by the Tang Dynasty (618-907 CE), tea drinking had become an art form, deeply integrated into Chinese culture. Tea cultivation began in earnest in mountainous regions, where the climate and soil conditions were ideal. Early farming methods were labor-intensive, relying on manual picking and processing.

From China, tea spread to other parts of Asia. Japan, for instance, received tea seeds and cultivation knowledge from Buddhist monks in the 9th century, leading to the development of unique Japanese tea traditions like matcha. Later, in the 17th and 18th centuries, the British East India Company played a pivotal role in introducing tea to the Western world. Realizing the immense profit potential, the British began cultivating tea on a large scale in their colonial territories, particularly in India (Assam and Darjeeling) and Ceylon (Sri Lanka), in the 19th century. This marked a significant shift in tea production, moving it beyond its traditional Chinese homeland and establishing it as a global commodity.

Today, tea farming is a highly specialised agricultural practice. Modern tea plantations employ a combination of traditional techniques and scientific advancements to maximise yield and quality. The process involves meticulous care, from nurturing young tea bushes to precise plucking, with skilled workers often hand-picking the tender leaves and buds to ensure the finest quality.

Global Tea Harvesters: A Geographical Overview

Tea is cultivated in numerous countries around the world, primarily within the “Tea Belt” – a region spanning between the Tropic of Cancer and the Tropic of Capricorn, characterised by warm temperatures, high humidity, and ample rainfall. The major tea-producing countries include:
