Green Tea Temperature: Sencha, Gyokuro & More
Water temperature, leaf amount and steep time for sencha, gyokuro, Longjing, hojicha and matcha, plus what lab data says about cooler water.
The quick version. Use water at about 70 to 80°C for most green tea, 50 to 60°C for gyokuro, and near boiling for roasted teas such as hojicha.
Key takeaways
- Sources agree on the pattern, not the exact degrees.
- Pour it from the kettle into a second cup, then into a third, then into the teapot.
- What temperature is best for green tea? About 80°C is a safe all-round answer. Use 70 to 80°C for sencha and 50 to 60°C for gyokuro, and go hotter for genmaicha, hojicha and bancha.
- For the first infusion, 60 to 90 seconds for sencha and one to three minutes for most other greens.
- Do tea bags need different water? The 2025 study found serving method (bag or loose) had no effect on measured caffeine in green and white teas.
Steep sencha for 60 to 90 seconds, and treat time and leaf amount as seriously as temperature. If your green tea is bitter, cool the water by pouring it between two cups first, then shorten the steep.
Green tea water temperature by type
| Tea | Water | Leaf and water | First steep | Notes |
|---|---|---|---|---|
| Gyokuro (shaded Japanese) | 50 to 60°C | 8 to 10 g to a small pot, for example 10 g in 80 ml at 60°C | 90 seconds to 3 minutes | 3 to 5 infusions, with the steep time halved after the first |
| Sencha (steamed Japanese) | 70 to 80°C | 6 to 8 g in 120 to 160 ml | 60 to 90 seconds | Up to 3 infusions: slightly hotter, shorter each time |
| Chinese pan-fired, such as Longjing | About 70 to 85°C | 2 to 4 g in 150 to 250 ml | 1 to 3 minutes | Sellers range from 70°C (Rare Tea Company) to 80 to 90°C (Yunnan Sourcing) |
| Genmaicha | Boiled water (Ikkyu gives no cooling step) | 6 g in 200 ml | 60 to 90 seconds | Roasted rice softens the astringency |
| Hojicha, bancha | Near boiling | 15 g to 600 to 650 ml for 5 cups | About 30 seconds | Roasting reduces what cool water protects |
| Matcha | 70 to 80°C | About 2 g in 70 ml, whisked | None | Thin matcha; thick uses 3 to 4 scoops in 40 ml |
Sources agree on the pattern, not the exact degrees. Ikkyu and Ippodo are Japanese tea merchants; the UK Tea & Infusions Association gives about 80°C for green tea in general; the Tea Association of the USA, as quoted by trade guides, gives 170 to 185°F (77 to 85°C). Where a producer prints a temperature on the pack, use that first.
Why cooler water helps, and what the lab says
The usual explanation is that catechins, which taste bitter and astringent, dissolve faster in hotter water, while amino acids such as L-theanine, which taste sweet and savoury, dissolve at lower temperatures. Tasters report this consistently. The lab evidence is less tidy:
- A 2025 Foods study brewed six tea types at 80°C and 100°C for 2, 5 and 10 minutes. Brewing temperature mattered little for L-theanine, and longer brewing raised both caffeine and L-theanine.
- A 2001 Journal of Agricultural and Food Chemistry study from Unilever found that the amounts of tea and water, infusion time and agitation were major determinants of what ends up in the cup, alongside leaf grade, bags and the tea itself.
So cool water is a sound habit and not a magic number. If green tea tastes harsh, shorten the steep or use less leaf before you chase another five degrees.
How to cool boiling water
Pour it from the kettle into a second cup, then into a third, then into the teapot. Ippodo's gyokuro instructions say three transfers bring boiling water down to about 60°C. Two transfers will land you nearer 80°C. A variable-temperature kettle skips the step.
A starting method
- Warm the pot and cups with a little hot water.
- Pick your leaf amount from the table. Use the compact Japanese ratio, about 5 g per 100 ml, for a short steep, or 2 to 3 g per 150 to 200 ml in a mug.
- Cool the water to the tea's range.
- Steep for the shorter time first, and taste.
- Pour out every drop. Water left on the leaf keeps extracting and makes the next infusion bitter.
- Resteep with slightly hotter water and a shorter steep.
Fixing a bad cup
- Bitter and drying: the steep was too long or the water too hot. Cut time before temperature.
- Thin and pale: too little leaf. Add leaf before extending time.
- Sweet but flat: raise the temperature by 5°C or use more leaf.
- Grassy and sharp: the leaf is stale; green tea loses its freshness fastest of the main tea types.
Common problems, answered
What temperature is best for green tea?
About 80°C is a safe all-round answer. Use 70 to 80°C for sencha and 50 to 60°C for gyokuro, and go hotter for genmaicha, hojicha and bancha.
Can I use boiling water for green tea?
You can for roasted teas such as hojicha and bancha. For sencha and Chinese greens it risks a bitter cup unless the steep is very short.
How long should green tea steep?
For the first infusion, 60 to 90 seconds for sencha and one to three minutes for most other greens. Gyokuro in the traditional small-pot method takes 90 seconds to three minutes at a low temperature.
Why is my green tea bitter?
Usually time or leaf amount, then temperature. Try a shorter steep first.
Do tea bags need different water?
The 2025 study found serving method (bag or loose) had no effect on measured caffeine in green and white teas. Follow the pack.
