Camellia sinensis: The Tea Plant

The recent announcement by the Food Safety and Standards Authority of India (FSSAI) clarified that a beverage can only be termed as tea if it originates from the plant Camellia sinensis. This article delves into the characteristics and significance of this vital plant.

About Camellia sinensis

Camellia sinensis belongs to the family Theaceae and is commonly recognized as the tea plant. It is the primary source of various tea varieties, including green tea, black tea, and oolong tea. This plant typically grows as a shrub or evergreen tree, reaching heights of up to 16 meters. It thrives in mountainous regions and can be cultivated at altitudes reaching 2200 meters.

Required Climatic Conditions

• Temperature: Optimal growth occurs within a range of 15°C to 23°C.
• Climate: A warm and humid climate with a minimum of 5 hours of sunlight daily is ideal.
• Rainfall: An annual rainfall of 150 to 300 cm, distributed evenly throughout the year, is essential.
• Soil: The plant prefers slightly acidic, calcium-free soil with a porous sub-surface for optimal growth.
• Terrain: Sloping terrain is preferred to ensure effective drainage.

Reproduction

The flowers of the Camellia species are complete and bisexual, featuring functional male (androecium) and female (gynoecium) parts, including stamens, carpels, and ovaries.

Global Distribution

This plant is primarily cultivated in subtropical and warm temperate zones of Southeast Asia. Major tea-producing countries include Bangladesh, Bhutan, China, India, Japan, Korea, and Malaysia.

Types of Tea Produced in India

• Green Tea: Leaves are quickly heated through steaming or pan-frying after plucking to prevent oxidation, retaining their green color.
• Oolong Tea: This tea undergoes partial oxidation, resulting in flavors and colors that fall between green and black teas.
• Black Tea: Fully oxidized before drying, this tea has a characteristic dark color and robust flavor.
• White Tea: Involves minimal processing, typically just withering and drying, which helps preserve its delicate nature.
