What is Gyokuro?
- Gyokuro (玉露) translates to "jade dew" in Japanese.
- It is a high-grade shade-grown Japanese green tea, prized for its umami flavor, sweetness, and low astringency.
- Known for its deep green color, smooth body, and delicate aroma.
Shading Process
- Gyokuro is shaded for 21 days before harvest using straw, cloth, or modern synthetic covers.
- The tea plants spend 10 days in slight shade and then 11 days in full shade.
- Shading reduces sunlight exposure by ~70–90%, which:
- ▲ L-theanine & glutamic acid = ▲ umami.
- ▼ catechins = ▼ bitterness/astringency.
- ▲ chlorophyll = vivid green color.
Cultivars Used
- Common cultivars include:
- Yabukita (most common)
- Saemidori
Brewing Recommendations
- Use a kyusu made for Japanese teas, or other teaware that can handle a smaller leaf.
- Use low-temperature water: 50–60°C (122–140°F).
- Steep for 90–120 seconds for the first infusion.
- Use about 1g of leaf per 10ml of water (e.g. 5g leaf to 50ml water).
- Multiple infusions are common, each shorter than the last.
Taste Profile
- Rich in umami, sweet, with marine or vegetal notes (like seaweed or steamed spinach).
- Smooth and round mouthfeel with minimal bitterness.
Cost & Rarity
- Gyokuro is typically more expensive than sencha due to:
- Labor-intensive shading and cultivation.
- Limited harvest windows.
- Handpicking in many high-grade examples.
Storage Tips
- Gyokuro is delicate and sensitive to storage conditions.
- Avoid heat, light, moisture, and strong odors.
- Store in an airtight, opaque container in a cool, dry place.
