Organic Japan Pu Erh Tea


This award-winning organic tea is Japan’s version of the famous fermented tea from China. Pu-erh (also spelled pu’er or pu’erh), a city located in the Yunnan Province of China, is the namesake of pu-erh tea, the most famous subset of Chinese heicha (dark tea). While not from Pu-erh, this Organic Japan Pu-erh Tea boasts one of the most innovative tea production techniques on the market, borrowing manufacturing methods from both pu-erh production and Japanese sake brewing. It begins with unoxidized green tea that is fermented using traditional sake kuro-koji bacteria. After four days of fermentation, the dried tea leaves turn dark brown and take on an aroma of toasted bread, dried fruit, and dark chocolate.

This one-of-a-kind loose leaf tea makes a brew that reminds us of a toasty Japanese Hojicha mixed with a medium bodied Chinese pu-erh, offering little astringency and a lighter version of the musty aroma traditionally associated with pu-erh tea. The smooth, dry cup has prominent notes of toasted grains, backed with stone fruit and baked apple. It is as delicious, as it is unique!

PS - Though this organic tea is made using a sake-style fermentation, it does not contain alcohol.

Ingredients: organic Japanese fermented tea

Origin: Osada Seicha, Shizuoka Prefecture, Japan


Located in central Japan, Shizuoka is known as the capital of Japanese green tea production. Though it is not the oldest producer of tea, it is the largest; this prefecture alone accounts for 40 percent of all green tea production in Japan. Mori Machi is located in an area of Shizuoka that is referred to as “organic tea’s home.” Osada Seicha, the manufacturer and tea garden, has been both growing and manufacturing tea since 1947 and has received numerous international and national awards including a Frontier Prize at the 2010 World Green Tea Contest for their Japan Pu-Erh Tea. For those concerned with the implications of the Fukushima-Daiichi disaster, we continue to have our organic teas from Japan independently tested for radiation.

Steeping Instructions


At Arbor Teas, we believe tea should be brewed to suit your personal taste. We’re happy to make recommendations to get you started, but don’t hesitate to experiment! When brewing your tea, your main considerations are tea quantity, water temperature, and steeping time. We recommend pu-erh teas to be steeped for 5 to 10 minutes in water heated to a full, rolling boil. For the best flavor, use fresh water whenever possible, and avoid overboiling. Try not to steep your tea longer than necessary, as you’ll extract undesirable bitterness from the leaves.If you want a stronger brew, don’t steep longer, just use more tea. And don’t forget to re-steep your tea leaves to get the most out of your leaf!

Staff Perspectives

  • Chelsea

    "This is a great pu-erh if you are looking for a dark tea with less of a musty flavor. This reminds me of toast and dried fruit, I love how non-astringent it is!"

  • Jeremy

    "I had the great honor of visiting Osada’s state-of-the-art production facility in Shizuoka, and was impressed by the painstaking process this tea receives during production. A truly novel tea!"

  • Aubrey

    "Don’t judge this tea by its stemmy, broken leaves, its appearance belies a precise, high quality production technique."

Health Benefits


Like all true tea, pu erh tea offers many potential health benefits. Research has found that tea (Camellia sinensis) can have many positive effects on human health, including improved cardiovascular function, cancer risk reduction, improved immune function, improved oral health, and help with weight management. Tea is also full of polyphenols, which are a class of antioxidant that help your body maintain homeostasis and balance your stress levels. Pu-Erh specifically has been used in Chinese medicine to support gut health, weight loss, and lower cholesterol.

    notes of chocolate and cherry, a real gem

    Posted by Benjamin Carnes on 26th Jun 2024

    I was stunned with the first sip. I never new tea could be this different and this good. It hits you right away with notes of chocolate and only the slightest pu-erh mustiness. It is rich and complex, best enjoyed with gongfu brewing. The flavour profile goes from chocolate to cherry. These leaves yield goodness for many brewings. The tea energy is good for creative days, but not for study focus days. It starts out heavy on tranquillity which fades as the caffeine then builds momentum towards giddiness.

    Pleasant and unique

    Posted by Robert Stanton on 28th Feb 2023

    I used 2.37g of tea leaf with 200ml water, steeped 5 minutes at 168F. Aroma of lightly fermented sweet red bean paste or brown lentils with a hint of smokiness and a bit of "Thai iced tea" character. Flavor is interesting, a little smoky, a little sweet, red bean paste-like taste with a bit of "Thai iced tea" flavor. Good, full mouthfeel. An interesting tea that I'll be trying more of.

    a little bland

    Posted by Skye on 6th Nov 2022

    I really enjoy Pu Erh and I loved the idea of this tea but I found it really light on flavor when I steeped it as directed. I only had a sample this time so I did 5 minutes and 10 minutes. I'm not giving up on it - I think I'll add another sample to my next order and try using more tea when I brew it. I'll update my review when I do. I definitely recommend you try steeping more leaves if your first steep is lighter on flavor than you'd like. Also, I should mention I spent a portion of my childhood in England and have a Scottish father, so my palate has been trained by the "tea so strong you can stand a spoon up in it" ethos. I have a tendency to prefer longer steeping times with Arbor Teas. So if you're someone who has a more delicate palate, that's something to consider in assessing my review. :) Happy steeping! I love Arbor Teas!

    A Well-Crafted Pu Erh

    Posted by Nicola on 27th Aug 2021

    Many pu erh connoisseurs might hold their nose at anything labelled pu erh made outside of Yunnan, but in flavor this is a pu erh through and through. The lovely people at Osada Seicha have created their own spin on this traditional tea, which may not be for everyone, but has a lovely, warm flavor, and is quite inviting for those willing to give it a shot. Remember to steep this one relatively long and hot to get it to release its full flavor.

    My new breakfast tea!

    Posted by Bill Buchanan on 3rd Apr 2021

    I'm a pu'erh drinker. I love that earthy, musty aroma and taste, but it's never been my morning ritual... until now. This Japan pu'erh will take over my morning from now on. The one issue I have always had with my breakfast teas (English, Irish, Scottish) was the astringency; I had to use more sugar than I care to, in order to cut that aspect. This tea is, to me, like the classic breakfast blend without the astringency, It's a unique blend of black breakfast tea without astringency, and pu'erh without heavy earthy must.

    Converted me to Pu Erh

    Posted by Daniel on 7th Mar 2019

    This stuff is amazing. No bitterness or astringency or anything like that, amazing for cold winter mornings. The leaves are not bitter and can be eaten as well

    A change, but a pleasant one

    Posted by Johanna on 9th Apr 2018

    Japanese green tea is my go-to in the morning and the flavors of this fermented one are a big departure from those, but it makes for a lovely change. The nose reminds me of wet leaves and tart cherry and dark chocolate... There's a bit of cedar too. It's a woodsy smell. The cherries and chocolate are what come through most in the flavor, along with (surprisingly) umeboshi! It was the perfect accompaniment for early spring mornings on my back porch. Another lovely tea from Japan!

    Organic Japan Pu Erh Tea

    Posted by Paul on 11th Feb 2018

    Very, very good - works both moderately sweetened or not sweetened. (When I drink regular pu erh, I have a lot of trouble imagining it sweetened.) It has a fermented flavor that resembles regular pu erh, but there's something different there, and it's not worse.
