Tea Brewing
Loose-Leaf Tea Water Temperature Guide
The single biggest cause of bitter tea is water that is too hot. Here are the temperatures we brew at, by tea type.
Key takeaways
- Green and white teas prefer 158-176°F (70-80°C); black and herbal teas can take a full boil.
- If your tea tastes harsh or drying, drop the water temperature before you shorten the steep.
- No thermometer? Boil, then rest the water 3-5 minutes for green tea.
Why temperature matters more than you think
Hot water pulls compounds out of the leaf in a rough order: aromatics first, then sweetness and body, then tannins and bitterness. Very hot water skips ahead and drags out the bitter end of that range in seconds.
That is why the same tea can taste floral in one cup and like a dry mouthful of pennies in the next. Nothing changed but the kettle.
Temperatures by tea type
Use these as starting points, then adjust to taste. A ten degree change is very noticeable.
- White tea: 167-176°F (75-80°C)
- Green tea: 158-176°F (70-80°C)
- Oolong: 185-203°F (85-95°C)
- Black tea: 203-212°F (95-100°C)
- Pu-erh: 203-212°F (95-100°C)
- Herbal and rooibos: 212°F (100°C)
Brewing without a temperature-controlled kettle
Boil the kettle and let it stand with the lid open. In a normal room, water drops roughly 18°F (10°C) in the first two minutes and slows from there.
Another trick: pour boiling water into your cup first, then into the pot. Each transfer sheds a few degrees and warms your vessel at the same time.
Troubleshooting by taste
Bitter and drying usually means too hot or too long. Thin and watery usually means too cool or not enough leaf. Change one variable at a time and write it down.
Frequently asked questions
- Can I use boiling water for green tea?
- You can, but expect bitterness. If boiling water is all you have, shorten the steep to about 45 seconds and use slightly less leaf.
- Does water quality matter?
- Yes. Very hard water flattens aroma and can leave a film on the surface. Filtered water is usually a bigger upgrade than a new teapot.
