How do I brew Gyokuro?

Use 3–4g per 100ml of leaf to 50–60°C (122–140°F) water and steep 2–3 minutes. Most quality Gyokuro can be re-steeped for 3–4 infusions.

Does Gyokuro contain caffeine?

Gyokuro is a green tea and is rated "high" caffeine. See the chemistry section on this page for cited ranges.

Where does Gyokuro come from?

Gyokuro is produced in Japan, specifically in the Uji region.

Why is gyokuro brewed with such cool water?

Gyokuro is brewed at 50-60C because cool water extracts the amino acids (particularly L-theanine) responsible for its sweet, umami flavor while leaving most of the bitter catechins behind. Hot water would release those bitter compounds and overwhelm the tea's distinctive sweetness. This is the single most important variable to get right when brewing gyokuro.

What does shading do to the tea plant?

Covering the plants for three to four weeks before harvest blocks sunlight, which causes the plant to produce more chlorophyll and L-theanine as it reaches for light. This is what gives gyokuro its deep green color, its low bitterness, and the pronounced savory umami flavor that sets it apart from regular sencha.

How much gyokuro leaf should I use per cup?

Gyokuro is typically brewed with a high leaf-to-water ratio: about 5-7 grams of leaf for only 60-80ml of water. The resulting small, concentrated pour is sipped slowly rather than drunk like a full cup of tea. Three short infusions of 90 seconds each are typical.

Gyokuro

Japan's most prized green tea, shade-grown for 20+ days to intensify amino acids and reduce bitterness.

Type: Green Tea
Origin: Japan · Uji
Oxidation: none
Caffeine: high
Brew temp: 50–60°C
Brew time: 2–3 min
Flavor notes: intense umami, sweet, marine
Harvest: Single harvest: April-May only. Shade-grown period begins 3-4 weeks before picking.

History

Gyokuro, meaning 'jade dew,' was created in 1835 by Yamamoto Kahei in Uji, Kyoto. He discovered that shading tea bushes before harvest dramatically changed the tea's character, producing an intensely sweet, umami-rich cup unlike any other. The technique of covering tea plants with reed or straw screens for 20+ days became the defining feature of gyokuro production. It remains Japan's most premium non-powdered tea, often reserved for special occasions and honored guests.

Processing

Steps: Shade-grow 3-4 weeks → Steam leaves → Cool and dry → Roll into needles → Final dry

Tea bushes are covered 20–30 days before harvest, dramatically increasing chlorophyll and L-theanine while reducing catechins. Only the most tender young buds and leaves are hand-picked. The leaves are then steamed, rolled into their characteristic thin needle shape, and dried. The shading process is what transforms ordinary tea leaves into gyokuro's extraordinary flavor.

Tasting Notes

First time? Gyokuro is unlike any green tea you have probably tried before, with an intense savory sweetness and deep umami flavor that can feel almost broth-like. Do not let the small brewing volume and low water temperature seem fussy, as they are what unlock the tea's remarkable character.

Appearance

Dark, glossy green needles that are tighter and more refined than sencha. The brewed liquor is a deep, vibrant green with a slight golden hue.

Aroma

Intensely sweet and marine - like nori seaweed combined with steamed spinach and a honeyed sweetness. The aroma alone signals its premium quality.

Taste

An overwhelming wave of umami - savory, sweet, and almost broth-like. The best gyokuro has virtually no bitterness, just layers of sweetness, marine depth, and a long, lingering finish that coats the palate.

Brewing Guide

Western Style

Leaf: 3–4g per 100ml
Water: 50–60°C (122–140°F)
Time: 2–3 minutes
Infusions: 3–4 infusions

Gongfu Style

Leaf: 5g per 60ml
Water: 50°C (122°F)
Time: 2 min first, 30s second
Infusions: 3–5 infusions

Step-by-step

Cool the water significantly. Heat water and then cool it to 50–60°C. This low temperature is essential - it's much cooler than most teas. Tip: Pour boiled water between cups several times to cool it naturally, losing about 10°C per transfer.
Use generous leaf. Add 3–4g per 100ml - more leaf than typical green tea, which creates a concentrated, rich cup. Tip: Gyokuro is meant to be sipped in small quantities, like fine wine.
Steep patiently. First infusion: steep for 2–3 minutes at 50–60°C. The slow extraction pulls out sweetness and umami without bitterness. Tip: Resist the urge to increase temperature - patience produces the best gyokuro.
Subsequent steeps. Second infusion at 60°C for 30 seconds, third at 70°C for 30 seconds. Each reveals new flavor dimensions. Tip: After the final steep, the softened leaves are edible and delicious with a drop of soy sauce.

Common Pitfalls

Brewing gyokuro at 80C or above destroys the shaded umami character - use water cooled to 50-60C for the richest cup.
Using too much water relative to leaf - gyokuro needs a very small volume (around 40-60ml) per 5g to concentrate its flavors properly.
Steeping for only 30 seconds as you would sencha under-extracts gyokuro - give it a full 90-120 seconds at the lower temperature.
Storing opened gyokuro at room temperature for weeks causes rapid flavor loss - keep it sealed in the fridge and use within a month.
Treating it like an everyday tea and rushing the preparation misses the point - gyokuro rewards patience and precise temperature control more than almost any other tea.

Buying Guide

What to look for

Very dark, glossy green needles with a uniform shape
Intense, sweet marine aroma in the dry leaf
Look for hand-picked (tezumi) designation for the highest quality
Single cultivar teas (especially Gokou or Saemidori) offer distinct character

Quality indicators

Uji, Yame, and Okabe are the premier regions
Shading duration of 20+ days indicates proper gyokuro
Competition-winning (品評会) designations mark exceptional quality
First harvest only - there is no 'second flush' gyokuro

Price range: $25–40 for good quality, $50–80 for premium single-origin, $100+ for competition-grade

Storage: Store in an airtight, opaque container in the refrigerator. Consume within 2–3 months of opening for peak umami. Gyokuro is more perishable than sencha due to its high amino acid content.

Fun Facts

Gyokuro contains 2–3 times more L-theanine than regular sencha due to shade-growing.
The shading process was discovered accidentally when farmers noticed shaded plants produced sweeter tea.
In Japanese tea culture, gyokuro is served in very small cups (about 30–50ml) to concentrate the experience.
Some gyokuro bushes are shaded with traditional reed screens (yoshizu) that cost more than modern alternatives but are said to produce superior tea.
Yame gyokuro from Fukuoka prefecture has won Japan's national tea competition more than any other region.
