Gyokuro is grown in the dark. For around three weeks before harvest the bushes are covered with reed screens or black netting, cutting out most of the sunlight and leaving the plant with more theanine and fewer catechins. The result is Japan's sweetest, most savoury leaf tea: thick, almost broth-like, with a deep marine umami and very little bitterness. It has to be brewed accordingly — a generous amount of leaf, a small volume of water at a low temperature, and a patient steep. Treated that way it is less a refreshing drink than a concentrated one, and the later infusions, brewed hotter, open it back up.
Tea Artisan: NishiさんKagoshima
The Nishi Gyokuro is produced in Kagoshima by Nishi Tea Factory led by Mr. Toshimi Nishi. The Nishi family is recognized for its meticulous tea production and organic farming philosophy, with fields and facilities designed to preserve the natural quality of the leaf from cultivation to processing.
Origin: KagoshimaJapan
This tea is sourced from Kagoshima, one of Japan’s most important tea-producing regions. The warm climate, volcanic soils and advanced tea farming culture of southern Kyushu make it especially well suited for shaded green teas like gyokuro.
Cultivar: SaemidoriTea variety
The Nishi Gyokuro is made from the Saemidori cultivar, one of the most prized tea plant varieties for shaded Japanese green tea. This cultivar was selected for its smooth sweetness, bright green color and ability to produce a clean, rich umami when carefully shaded.
Saemidori: Saemidori is a highly respected cultivar created from Yabukita and Asatsuyu. It is known for producing teas with a vivid green color, low astringency and a naturally sweet flavor. In gyokuro, Saemidori can express a deep umami profile while staying elegant, floral and smooth.
Preparation & ServingsUp to 30 cups
Hot brew: 5 g of leaves, 150 ml of water at 60°C (140°F), 2 minutes.
Brew it again: the same leaves give 3 infusions. Re-infuse 2 more times with water at the same temperature, 20 seconds each; every infusion tastes a little different.
Cold brew: Nishi Gyokuro also works beautifully as a cold brew. Add 5 grams of leaves to 500ml of cold water and let it infuse in the fridge for 3 to 6 hours. The result is smooth, sweet and almost broth-like, with very little bitterness.
One pack: Up to 30 cups · 10 × 5 g servings, 3 infusions each · 50 g / 1.8 oz.

How to Make Gyokuro Like a Pro
The Nishi Gyokuro should be prepared with cooler water and a longer infusion than a standard sencha. This allows the sweet and savory compounds to unfold gently without pulling out too much bitterness. A lower temperature is especially important for preserving its dashi-like umami and delicate floral notes.
Heat the Water
Heat water to 60°C (140°F).
Add the Leaves
Add 5 g of leaves to a kyusu or shiboridashi.
Steep
Pour 150 ml of water and steep for 2 minutes.
Pour & Brew Again
Pour out every drop, then brew the same leaves 2 more times (20 seconds each).

Why Organic Gyokuro Fields Make a Difference
Tea plants absorb everything from the soil, making pesticide-free farming especially important. The farmers we work with have found a way to grow delicious tea without harming the natural ecosystem.
Nio teas has been my favourite place to purchase good quality teas for a while now, and still they never disappoint me. Their teas are excellent quality, however, I’d like to give more attention to customer service - Nio team has been very kind and helpful each time I had any sort of problem. Their customer service never disappoints, they are very attentive and quick in responding to any queries, hence why I’ve been a loyal customer for a while now.

My favorite vendor for Japanese organic loose leaf green teas. They are sourcing some of the best organic teas out of Japan and supporting family farmers and the growing organic tea industry as a whole.I have ordered from every vendor for years and Nio consistently has the best prices and selection overall. They provide top notch customer service and fast shipping as well. Highly recommended 🍃
Shipping is free once your order passes the threshold for your country — USD 54.99 · EUR 54.99 · GBP 44.99 · CHF 49.99 · CAD 74.99 · DKK 399 · SEK 599 · PLN 229 · CZK 1,290. Everywhere else it's the equivalent of USD 54.99, converted automatically. Below the threshold a flat rate applies, always shown at checkout before you pay.
We ship from warehouses in the US, the EU and Japan — whichever is closest to you. US and EU orders arrive in 4–12 business days; the handful of countries served from Japan take around 10. Business days count from dispatch rather than from when you order, and exclude weekends and public holidays. You'll get a tracking number by email the moment your parcel leaves the warehouse.
We only buy from fields grown without pesticides or chemicals. We ask each farmer directly how they manage their land, visit the plantation and processing facility ourselves, taste every harvest before committing, and check that the biodiversity around the fields is alive. Small family farms don't always carry paperwork — so we verify it in person instead.
Japanese green tea covers an enormous range, and choosing online isn't easy. If you've tried yours and it isn't for you, email info@nioteas.com within 30 days with your order number and a line on what you didn't enjoy. We'll send a different tea of equal or lower value, free. Nothing to post back — keep it, share it, or try brewing it cooler. Once per order.
Email info@nioteas.com within 30 days with your order number and a photo. We'll approve it, cover the return postage with a prepaid label or a reimbursement, and refund you — no restocking fee. Refunds go to your original payment method within 2 business days of the return reaching us; your bank may take another 5–20 to show it.
Unopened items in their original packaging can be returned within 30 days. Tea is sealed for hygiene, so opened packs can't come back — but the swap above covers exactly that situation. Return postage is yours unless the item arrived damaged, defective or incorrect.
Orders to the US and EU ship domestically from our local warehouse, so there's no customs charge and no duty. A small number of destinations are served from our Japan warehouse, where your own customs authority may apply import duty, VAT or a carrier handling fee on delivery. Those are set by your country, not by us. Ask before you order and we'll help you check.
Lo ricomprerei. Nel frattempo sto cercando di provare anche gli altri gyokuro. Aver trovato questo sito da cui acquistare è stata una gran fortuna. Grazie :)
