While Thai Tea is famous for its vibrant orange glow on the streets of Bangkok, its soul is forged 800 kilometers north, in the rugged, mist-covered mountains of Chiang Rai.
The tea plantations of Mae Salong and Choui Fong benefit from a unique microclimate. The high altitude ensures cooler temperatures and frequent mist, which slows the growth of the tea leaves. This "stress" allows the plant to develop a higher concentration of aromatic compounds and antioxidants compared to lowland tea.
The soil in Chiang Rai is naturally rich in iron and slightly acidic—perfect conditions for the Camellia sinensis var. assamica plants that form the backbone of a traditional Thai Tea blend.
Unlike traditional Chinese green teas, the leaves destined for Thai Tea undergo a deep oxidation process. They are roasted with specific spices—star anise, cloves, and sometimes cinnamon—which gives them that deep, ruby-red base that turns sunset orange when mixed with milk.
In 2026, we are seeing a shift toward "Single Origin" Thai Tea. Instead of mass-market blends, premium shops are now specifying the exact village in Chiang Rai where their leaves are harvested. Look for labels mentioning Doi Mae Salong for the most refined floral notes.
