Key Takeaways
- Every tea family has its ideal water temperature, ranging from cooler water for delicate white teas to near-boiling water for black teas.
- Over-dosing leaf quantity is usually to blame for bitterness incorrectly blamed on tea quality.
- Steeping time matters just as much as temperature: steeping just one minute too long can ruin cup balance.
- Poor water quality, such as hard or chlorinated tap water, can mask subtle tea flavors.
Why Water Temperature Changes Everything
Boiling water for every tea is the most common mistake. Each tea family undergoes different processing and handles heat differently. Delicate white tea degrades under high heat, turning flat or bitter. Conversely, black tea requires near-boiling water to release its full body and rich aromas.
This explains why many people find green tea "bitter": they steep it in boiling water meant for black tea, rather than using cooler water that lets its true character emerge.
Leaf Dosage: The Overlooked Variable
The volume of tea leaves used is equally critical. Over-dosing concentrates tannins, creating an astringent, bitter cup. Under-dosing results in a weak, watery brew, tempting people to steep longer to compensate—which only increases bitterness.
Stick to a precise ratio (typically 2 to 3 grams per 200 ml of water) rather than trying to adjust strength by altering steeping times.
| Tea Type | Water Temp | Steeping Time |
|---|---|---|
| White Tea | 80-85 °C | 3 to 5 minutes |
| Green Tea | 70-82 °C | 1 to 3 minutes |
| Black Tea | 90-95 °C | 3 to 5 minutes |
| Rooibos | 95-100 °C | 5 to 10 minutes |
Why water quality matters. Chlorinated or heavily mineralized tap water hides subtle tea notes. Using filtered water can noticeably elevate the flavor of your brewed tea.
Field Tip
I always time my steeping with a timer rather than guessing. Just one extra minute can turn a balanced green tea unpleasantly bitter.

FAQ — Dosing and Steeping Tea
Why is my green tea always bitter?
Green tea becomes bitter when steeped in water that is too hot or left steeping too long. Use cooler water (70-82 °C) and steep for 1 to 3 minutes.
Should I use more tea leaves for a stronger cup?
Yes, increase the dry leaf quantity slightly rather than extending the steeping time, which prevents harsh tannin extraction.
