Vietnamese iced tea — weak green or jasmine tea served chilled, free at every street eatery as a hospitality default.
The free-iced-tea custom traces to northern Vietnam's bia hoi (fresh-beer) culture, the cheap quick-ferment draft beer that emerged in Hanoi around the 1950s amid wartime rice rationing and southern street stalls in the 20th century. Tea has been grown in Vietnam since the 11th century — Phu Tho and Thai Nguyen are the two heritage regions. Free service at meals is post-1950s urban norm.
A 2018 Hanoi food survey found 89% of pho shops served tra da free, treating it as part of the meal contract. Vietnamese tea export was 138,000 tonnes in 2023, mostly low-grade for this segment. Phu Tho's Bach Hac green tea is the home-quality benchmark.
Pale yellow-green, served in a small glass over a few ice cubes, often refilled without asking. Light grassy bitterness, sometimes a faint jasmine perfume. Drink it like water — that's its job.
Tea is brewed weak — 1g leaf per 200ml of water at 80°C — to be drunk in volume without bitterness or caffeine overload. Brewed warm, then chilled. Many stalls use the previous batch as iced filler topped with fresh hot brew.
Variations
North uses green tea (tra xanh), south leans jasmine (tra lai). Hue serves lotus-flower-scented tea (tra sen). Some bia hoi stalls add a wedge of kumquat (tra da chanh) — that turns it into a paid drink.
