Sencha is brewed in three steps: water at 70–80°C, about one minute of steeping, and re-brewing the same leaves two or three more times. That is the entire technique. The reason it produces a better cup than a single long steep is that sencha gives different compounds to the water at different temperatures and durations — so a series of short, controlled steeps gives a more complete cup than one long one.
Here is the method in detail.
What you need
- A kettle that will heat to a known temperature — or boil and let it cool.
- A teapot, ideally a Japanese kyusu (a small side-handled pot with a built-in mesh strainer) or any small teapot with a built-in or removable strainer.
- Good loose-leaf sencha, fresh — within nine months of harvest.
- A small pouring vessel (yuzamashi) is helpful but not essential. It is used to cool boiling water before pouring it on the leaves.
The water
Sencha is brewed cooler than almost any other tea. The optimal temperature is between 70 and 80°C (158–176°F). Boiling water (100°C) pulls out the catechins that produce bitterness; cooler water leaves them behind and emphasizes the L-theanine and amino acids that produce sencha's signature savoury umami note.
If your kettle has temperature control, set it to 75°C. If not, boil the water and let it sit in the open kettle for two to three minutes (or pour it into a yuzamashi to cool more quickly). Each pour from kettle to vessel drops the temperature by about 10°C, which is a useful shortcut.
Use filtered or bottled water. The chlorine in tap water dulls sencha's flavor more than it does a robust black tea.
The leaf-to-water ratio
- Roughly 3 grams of sencha per 100 ml of water for a Japanese-style brew.
- If you do not weigh — about one rounded teaspoon per small cup.
- Use more leaf than you would for a Western brew. Japanese tea is built around short steeps with a high leaf-to-water ratio, not long steeps with a low one.
The first steep
- Pre-heat the teapot and cups by pouring hot water into them, swirling, and discarding.
- Place the sencha leaves in the teapot.
- Pour the cooled water (75°C) over the leaves.
- Steep for 60 seconds.
- Pour out every drop into a serving pitcher or directly into cups. Do not let the leaves sit in the remaining water — they will continue extracting and the next steep will be off.
The first cup should be pale green-yellow, savoury, with a faint sweetness and a clean vegetal finish.
The second steep
For the second steep, use slightly hotter water (about 80°C) and a much shorter time:
- Water: 80°C.
- Time: 20–30 seconds.
The leaves have already unfurled and the compounds extract faster the second time. The cup will be a touch darker, slightly more vegetal, and often more aromatic than the first.
The third steep
If the sencha is high-grade, a third steep is worth doing.
- Water: 85°C.
- Time: 45–60 seconds.
By the third steep the leaves have given most of what they have. The cup will be lighter and more delicate; it is a different drink from the first two, and pleasant in its own right. Some sencha will give a useable fourth steep, particularly the early-harvest grades.
Troubleshooting
The cup tastes bitter or astringent. Almost always because the water was too hot. Drop to 70°C and try again. Less commonly: too much leaf, too long a steep, or old tea.
The cup tastes thin or watery. Either the water was too cool (under 65°C) or you used too little leaf. Increase the leaf or push the water to 80°C.
There are floating particles in the cup. Sencha leaves are finely broken in processing, and a small amount of leaf dust ends up in the cup. This is normal; it does not mean the tea is low quality. The Japanese name for these particles is konacha and it is considered desirable. Some drinkers chew them.
The tea tastes flat or dull. Almost certainly age. Sencha is a freshness-driven tea; nine months past the harvest date and the aromatics fade meaningfully. Check the harvest year on the label and replace anything more than a year old.
The cold-brew alternative
For warm weather, cold-brewed sencha is excellent and even easier:
- 10 grams of sencha per liter of cold filtered water.
- Steep in the refrigerator for 6 to 8 hours.
- Strain and drink.
The cold extraction pulls out the amino acids and L-theanine but leaves most of the catechins behind, producing a smooth, sweet, almost broth-like cup with very low astringency. Some Japanese houses make a feature of cold-brew sencha as a summer specialty.
FAQ
How hot should the water be for sencha?
70–80°C (158–176°F). Boiling water is too hot and brings out bitter compounds. The Japanese rule of thumb is: cooler water for higher-grade sencha, slightly hotter for lower-grade.
How long should I steep sencha?
About 60 seconds for the first steep, 20–30 seconds for the second, 45–60 seconds for the third. A long single steep is the most common Western mistake; it produces a bitter cup and wastes the leaf's second and third extractions.
How many times can I steep sencha?
Two or three times is the standard. The best sencha will give a useable fourth. After that the leaves are exhausted.
Can I brew sencha in a regular Western teapot?
Yes, but a kyusu makes the technique easier because the built-in strainer keeps the leaves separated from the liquor between steeps. If using a Western pot, pour off every drop after each steep to avoid over-extraction.
Why does my sencha look cloudy?
Cloudiness from suspended leaf particles is normal and considered a sign of fresh sencha. If the cloudiness has an off smell or a metallic taste, it is more likely a sign of old leaves or hard water.
The Saint Graal Sencha rewards the three-steep method. The first cup is umami-forward; the second is more vegetal; the third is gentler and aromatic. See the cup →
