As the morning mist rolls across the volcanic slopes of West Java, tea pickers carefully harvest tender leaves that will soon become fragrant cups enjoyed across Indonesia and beyond. In the bustling streets of Kuala Lumpur, a tea master theatrically pours steaming teh tarik between two metal cups, creating its signature frothy texture. Hundreds of kilometers away in northern Thailand, visitors sip delicate oolong overlooking emerald tea terraces, while families in Myanmar gather around a shared plate of lahpet thoke, the country's iconic pickled tea leaf salad.
On May 21, 2026, as the world celebrates International Tea Day, Southeast Asia honors one of its most enduring agricultural and cultural treasures. Across the region, tea is far more than a beverage. It is a symbol of hospitality, a source of rural livelihoods, an important export commodity, and a tradition that continues to unite generations through shared conversations and daily rituals.
A Cup That Tells Southeast Asia's Story
Every country in Southeast Asia has developed its own distinctive tea culture.
Malaysia and Singapore are renowned for teh tarik, the beloved "pulled tea" whose dramatic preparation has become an icon of street food culture. By repeatedly pouring black tea blended with condensed milk between two vessels, tea makers create a smooth, creamy texture while naturally cooling the drink.
Thailand's vibrant orange cha yen, or Thai iced tea, has become an international café favorite. Infused with black tea, spices such as star anise and cardamom, sweetened condensed milk, and served over ice, it reflects the country's rich culinary creativity.
Indonesia's relationship with tea is equally distinctive. Sweet jasmine tea, commonly known as teh wangi, accompanies countless meals across the archipelago. Bottled jasmine tea has become one of the country's most recognizable beverages, demonstrating how tea has become deeply woven into everyday Indonesian life.
Myanmar offers perhaps the region's most unique tradition. Rather than simply drinking tea, people also enjoy fermented tea leaves in lahpet thoke, a flavorful salad mixed with garlic, peanuts, sesame seeds, tomatoes, and crispy beans. For centuries, it has symbolized hospitality, reconciliation, and community gatherings.
Together, these traditions demonstrate that tea is as much about people and culture as it is about agriculture.
The Highlands That Grow Excellence
Behind every cup lies a remarkable agricultural landscape.
Indonesia remains one of the world's leading tea-producing nations. The fertile volcanic soils of West Java, Central Java, and North Sumatra provide ideal conditions for cultivating premium black, green, and specialty teas. Tea plantations established during the nineteenth century continue supporting thousands of farming families while contributing significantly to the country's agricultural exports.
Vietnam has earned international recognition for its ancient Shan Tuyet tea, harvested from centuries-old wild tea trees growing in the misty mountains of Hà Giang, Yên Bái, and Sơn La. Many of these towering trees are several hundred years old and continue producing leaves prized for their complex flavors and rich cultural heritage.
Northern Thailand tells another inspiring story. Regions such as Chiang Rai and Mae Salong have transformed from former opium-growing areas into internationally respected producers of high-quality oolong and green tea. This successful agricultural transition has strengthened rural economies while promoting sustainable land use and ecotourism.
According to the Food and Agriculture Organization, tea provides income for millions of smallholder farmers worldwide, with Asia accounting for the overwhelming majority of global production. Across Southeast Asia, the industry continues to support employment, exports, and regional food systems.
The Hands Behind Every Harvest
International Tea Day also recognizes the people whose dedication makes every harvest possible.
Across Indonesia, Vietnam, Thailand, and Myanmar, tea cultivation remains highly labor-intensive. Much of the region's premium tea is still carefully hand-picked, with skilled workers selecting only the youngest leaves to ensure superior quality.
Women make up a significant proportion of the tea workforce, contributing not only to harvesting but also to processing, sorting, packaging, and quality control. Their expertise helps preserve generations of traditional knowledge while sustaining local economies.
As Indonesian tea researcher Dr. Yuke Sri Rahayu of the Tea and Quinine Research Center has often emphasized, improving tea quality begins with empowering farming communities through innovation, sustainable cultivation, and continuous knowledge sharing. Likewise, Professor Dr. Nguyen Van Bo, former President of the Vietnam Academy of Agricultural Sciences, has consistently highlighted that strengthening agricultural value chains depends on supporting farmers with better technology, fair market access, and climate-resilient farming practices.
Ensuring fair wages, safe working conditions, healthcare access, and equitable market opportunities remains essential for securing the long-term future of Southeast Asia's tea industry.
Climate Change in Every Cup
Tea plants thrive under specific combinations of temperature, rainfall, and altitude, making them especially sensitive to climate change.
Across Southeast Asia, irregular monsoon seasons, prolonged droughts linked to El Niño, and increasingly intense rainfall events are affecting harvest schedules, leaf quality, and overall productivity. Rising temperatures are also shifting suitable growing zones toward higher elevations, placing additional pressure on farmers with limited land resources.
Encouragingly, many tea-producing regions are embracing more sustainable approaches.
Tea estates in Malaysia's Cameron Highlands, northern Thailand, and Indonesia's highlands are expanding organic cultivation, reducing pesticide use, protecting surrounding forests, and promoting biodiversity within plantations. Many have also diversified into agrotourism, welcoming visitors to experience tea harvesting, factory tours, tasting sessions, and scenic landscapes that generate additional income for local communities.
These innovations demonstrate that environmental stewardship and agricultural prosperity can grow together.
Steeping a Sustainable Future
International Tea Day reminds us that every cup represents far more than a refreshing drink.
It carries the work of farmers rising before dawn, the traditions of communities preserving generations of knowledge, the biodiversity of mountain ecosystems, and the resilience of rural economies adapting to a changing climate.
Across Southeast Asia, governments, researchers, cooperatives, tea producers, and local communities are increasingly working together to promote sustainable farming, strengthen fair trade practices, conserve natural landscapes, and celebrate the rich cultural heritage that tea embodies.
As the region continues balancing economic growth with environmental responsibility, tea remains a quiet but powerful symbol of harmony between people and nature.
On this International Tea Day, every shared cup brewed across Southeast Asia tells a story of heritage, resilience, and hope. From Indonesia's volcanic plantations to Vietnam's ancient tea forests, from Malaysia's bustling tea stalls to Thailand's mountain terraces, tea continues to connect cultures, nourish livelihoods, and cultivate a more sustainable future—one cup at a time.
