Tea brewing temperature guide
Green and white teas want cooler water; black, pu-erh, and herbal want a full boil. A simple temperature-and-time chart for every type of tea, plus no-thermometer tricks.
Different teas need different water temperatures. Delicate green and white teas want cooler water (160–185°F); oolong wants medium (185–205°F); and black, pu-erh, and herbal teas want a full boil (200–212°F). Too-hot water scorches delicate leaves and makes them bitter; too-cool water under-extracts robust ones. Here's the whole chart.
Temperature & time by tea type
| Tea | Temp (°F) | Temp (°C) | Steep time |
|---|---|---|---|
| White | 160–185 | 71–85 | 2–5 min |
| Green | 160–180 | 71–82 | 1–3 min |
| Oolong | 185–205 | 85–96 | 3–5 min |
| Black | 200–212 | 93–100 | 3–5 min |
| Pu-erh | 200–212 | 93–100 | 3–5 min |
| Herbal / tisane | 200–212 | 93–100 | 5–7 min |
Why temperature matters
The rule of thumb: the less oxidized the tea, the cooler the water. Green and white teas keep fresh, heat-sensitive compounds that turn bitter when scorched, so they want cooler water and short steeps. Fully oxidized black tea and sturdy herbals need a full boil to extract properly. Oolong sits in the middle. For the oxidation background, see what is tea oxidation.
No thermometer? Use these tricks
- Full boil (~212°F): rolling bubbles — for black, pu-erh, herbal.
- ~185°F: boil, then wait about 1 minute — for oolong.
- ~175°F: boil, then wait 2–3 minutes (or add a splash of cold water) — for green and white.

Frequently asked questions
What water temperature is best for tea?
It depends on the tea. Green and white: 160-185°F. Oolong: 185-205°F. Black, pu-erh, and herbal: a full boil, 200-212°F. The less oxidized the tea, the cooler the water.
Should you use boiling water for all tea?
No. Boiling water is right for black, pu-erh, and herbal teas, but it scorches delicate green and white teas and makes them bitter. Let the kettle rest a couple of minutes for those.
How do I get the right temperature without a thermometer?
Boil the kettle, then wait: about 1 minute of cooling gets you near 185°F for oolong, and 2-3 minutes gets you near 175°F for green and white tea. A full rolling boil is for black and herbal.
Does water temperature really change the taste?
Yes, a lot. Too-hot water over-extracts delicate teas into bitterness; too-cool water leaves robust teas weak and flat. Matching temperature to the tea is the single biggest brewing fix.
