Post-fermented tea is made by putting finished leaf through a controlled fermentation, a step no other Japanese tea category uses. Ours is fermented in Uji with koji, the same mould used to make soy sauce, sake and miso, and that is what gives it its pink colour and its gentle acidity. The result tastes almost nothing like green tea: strawberry-like and slightly tart, which is why it is known in Japan as the rose of tea. Fermentation leaves very little caffeine behind, so it can be drunk at any hour, hot or chilled over ice. It is the most unusual tea we sell, and the one we would hand to someone who thinks they do not like tea.
Tea Artisan: TakadaさんKyoto
The Nadeshiko Rose Japanese fermented tea comes to us from the talented farmers at Chanoka in Uji. When we visited Mr. Takada, he introduced us to so many different types of rare teas and this is one of them.
Mr. Takada and his family have been in the tea industry since 1907 when they opened their tea plantation. He is able to lean on multiple generations of tea knowledge to produce excellent quality green tea, oolong tea, black tea and Japanese fermented tea.
Origin: UjiJapan
This Japanese fermented tea is produced in Uji, Japan. Uji is known for consistently producing some of the best quality teas in Japan. The soil is great quality, the air is clean and misty, the terrain is hilly and the winters are relatively mild with no frost. This climate has produced excellent teas for hundreds of years.
Cultivar: BenifuukiTea variety
The Nadeshiko rose Japanese fermented tea is made using the Benifuuki cultivar, which is normally reserved for Japanese black teas or “wakocha”
Benifuuki: The benifuuki cultivar has a higher concentration of catechins, so while it produces an astringent green tea, the variety works exceptionally well in black teas and Japanese fermented teas. The teas produced with Benifuuki yield a smooth taste and excellent aroma, as the fermentation and oxidation process really mellows out the catechins.
Preparation & ServingsUp to 60 cups
Hot brew: 5 g of leaves, 150 ml of water at 60°C (140°F), 1 minute.
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: best enjoyed hot, we do not recommend cold brewing this tea.

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.

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.
