Japanese tea varietals require specific water temperatures. A variable-temperature kettle is not a luxury — it’s essential for brewing proper sencha (70°C), gyokuro (50°C), or matcha (80°C).
Temperature Guide
| Tea | Ideal Temp | Steep Time |
|---|---|---|
| Gyokuro | 50°C (122°F) | 2 min |
| Sencha (middle grade) | 70–80°C (158–176°F) | 1 min |
| Hojicha / Genmaicha | 90°C (194°F) | 30 sec |
| Matcha | 80°C (176°F) | Whisk |
