Thailand's tea traditions run deeper than the famous orange iced tea — herbal teas, chrysanthemum, and the new specialty scene.
The ubiquitous orange Thai iced tea is brewed strong with spices (star anise, tamarind) and condensed milk — served in bags or cups, 20–40 THB from carts.
A clear, slightly sweet flower tea served hot or cold — gentle, naturally caffeine-free, found at Chinese-Thai restaurants and street stalls.
Pale green tea brewed from pandan leaves — subtle, slightly grassy, naturally sweet; often served at Thai restaurants as a palate cleanser.
A specialty tea wave has followed coffee's lead — Mariage Frères and TWG at high-end malls; local artisan tea shops in Ari and Thonglor.
Chinatown herbal shops and Or Tor Kor Market sell loose-leaf and packaged Thai teas at far better prices than mall boutiques, and staff are generally happy to explain what each blend is for.
Most Thai teas can be ordered either way regardless of tradition — simply specify "ron" for hot or "yen" for iced when ordering, and vendors will adjust accordingly.
