Synopsis: Tea is the world's second most-consumed beverage after water. Consumption patterns reveal deep cultural bonds. Türkiye leads per capita consumption at about 3.16 kg per person annually-translating to hundreds of cups per person, often enjoyed in tulip-shaped glasses as a symbol of hospitality.

In the quiet steam rising from a simple cup, an ancient story unfolds-one of discovery, resilience, connection, and quiet power.

From the misty hills in China thousands of years ago to bustling markets and serene tea rooms worldwide, the humble Camellia sinensis leaf has transcended continents, cultures, and centuries.

It has soothed emperors and labourers alike, sparked global trade, and today, brings billions of people a daily moment of pause and pleasure.

On International Tea Day, observed every 21 May, we celebrate this remarkable leaf that continues to conquer hearts and economies with grace and vigour.

Proclaimed by the United Nations General Assembly in 2019, International Tea Day highlights tea's rich cultural heritage, its contributions to sustainable development, and its vital role in supporting rural communities, especially in developing nations. It is a day for tea lovers everywhere to reflect on how one plant fosters health, community, and economic opportunity across the globe.

An accidental brew

Legend holds that around 2737 BCE, Chinese Emperor Shennong discovered tea when leaves from a wild Camellia sinensis tree fell into his boiling water. Whether myth or rooted in truth, archaeological evidence confirms tea's use in China over 2,000 years ago.

It evolved into a sophisticated beverage during the Tang Dynasty, spread to Japan and Korea, travelled the Silk Road, and reached Europe in the 16th-17th centuries through traders. What began as a medicinal infusion became one of humanity's most beloved daily rituals.

All "true" teas-black, green, white, oolong, and pu-erh-derive from the same plant. The differences arise from harvesting, withering, oxidation, and firing processes. Herbal infusions like chamomile or rooibos enrich the broader tea culture, but the Camellia family remains the undisputed sovereign.

The tea business

Tea is big business with even bigger human impact. Global production reached about 7.05-7.1 million metric tonnes in 2024, continuing a steady upward trend. China dominates with roughly 3.7 million metric tonnes, accounting for over 50% of global output and excelling in green tea.

India follows with around 1.28-1.5 million tonnes, renowned for its bold Assam and elegant Darjeeling black teas. Kenya ranks third as a major exporter of black tea, while other key players include Türkiye, Sri Lanka, Vietnam, and Indonesia.

Smallholder farmers produce about 60% of the world's tea, sustaining rural livelihoods. The industry supports an estimated 13 million people globally, many in small-scale operations across Asia and Africa.

Economically, the global tea market was valued at around US$69-86 billion in recent estimates and is projected to grow significantly, driven by demand for premium, speciality, and functional teas.

Exports provide crucial revenue for producing countries, while domestic consumption absorbs much of the harvest.

Ireland, the UK, Azerbaijan, and Pakistan follow with strong traditions. In sheer volume, China and India top the charts due to their population size. Notable mentions include high consumption in Sri Lanka and Argentina, the latter influenced heavily by yerba maté.

In India, masala chai is a street-side social ritual. In Japan, matcha embodies mindfulness. In Britain, afternoon tea remains a cherished custom.
