Organic Korea Sejak Green Tea


Teas from Korea are just beginning to gain popularity in the United States. Widely unknown, Korean Green Tea is one of the best kept secrets. More akin to a Japanese green tea flavor profile than a Chinese green tea flavor profile; this Organic Sejak Green Tea has a brothy and boldly vegetal cup that pleasantly lingers in the mouth with smooth, mild astringency. The liquor color reminds of an early spring dandelion and the wet leaves smell of dried straw and cooked asparagus with a brighter and thinner cup than our Organic Woojeon Green Tea from Korea. Grown on the volcanic island of Jeju, this loose leaf organic green tea is infused with the salty sea breezes and fertile soil of this pristine area of the world.

Ingredients: organic Korean green tea

Origin: Jeju Island, South Korea


Jeju is the largest island off the coast of the Korean Peninsula, and was formed entirely by volcanic eruptions. The island is still dominated by Hallasan, the largest volcano and mountain in South Korea. The volcanic soil and humid subtropical climate on the island has made it ideal for growing tea, and most of the Korean teas exported to America come from Jeju.

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 green and white teas to be steeped for 2 to 3 minutes in water heated to not-quite-boiling, just as bubbles begin to form on the bottom of the pan (approximately 170 to 180 degrees F). For the best flavor, use fresh water whenever possible. 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

  • Trish

    "A savory treat for sure! For me, this green tea has a delightful buttery cooked vegetable taste that gets me ready for the day. The dry leaves are so silky and green. It makes a beautiful cup of tea!"

  • Jeremy

    "With leaves slightly larger than the Woojeon leaves, this Sejak is a great example of young Korean teas leaves harvested in late April to May. "

  • Aubrey

    "If you like Sencha Green, then try this tea! It has a similar flavor profile with a Korean twist and is a great alternative for someone looking to replace their Sencha with a new organic tea or want to mix it up!"

Health Benefits


Like all true tea, green 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.

Green tea specifically is known for its array of health benefits, which have been supported by a growing number of studies. Green tea research has demonstrated that it may be an effective anticancer agent for breast cancer, lung cancer, kidney cancer and prostate cancer, among others. Studies have shown a link between green tea and weight loss, and the ability to modulate energy metabolism, aid in body fat regulation, and possibly promote preferential loss in abdominal fat. Research has also shown that green tea may increase performance for short term memory tasks, as well as being increasing potency of antibiotics. Other peer-reviewed studies link green tea to healthy skin, help with lowering cholesterol, and regulating diabetes. It’s important to keep in mind that many of these studies monitor subjects who drink several cups of green tea per day.

    Some interesting minerality and slightly anise-toned herbaceous quality but overall flavor profile is a bit one-note, not getting much umami and body is essentially absent. Looks like fairy mature leaves . Recommend 2-2.5 tsp for 8 oz water at 165 x3 min

    Pleasantly surprised

    Posted by Keiko S on 30th Dec 2023

    Although I drink lots of green tea I had never heard of this one before and ordered just a sample pack to try it. I thoroughly enjoyed the fresh and very pleasant smell and taste and ordered a bigger bag right away :)

    Fresh as dewy spring

    Posted by Mary on 18th Mar 2023

    Since I prefer vegetal, brothy green teas over high tannin ones, Korea Sejak is on my top 3 fav list. Number one is gyokuro. Some people look forward to waking up to coffee; I wake up for Sejak (and gyokuro).

    Pleasant grassy nose but little taste

    Posted by Starla on 26th Jan 2022

    I was initially hopeful when I brewed this up as it had a nice vegetal smell, but the taste didn't deliver. Could be improved with using more tea, but it's more expensive than my favorite OG Kukicha from Arbor, which is vegetal and super flavorful without being bitter. So not a fan.

    Has a lot more flavor without that dirt taste of Japanese green tea. Strong! My skin looks so much better and I lost a few pounds. There seem to be a lot of health benefits and antioxidants to true green tea, and so I will keep taking it several times a day! I think Arbor Tea is the best, I buy several types of their tea. My kids love trying all the different types.

    Don't let this be your 1st organic tea

    Posted by Nat E. on 23rd Oct 2020

    The transaction, packaging and delivery were super easy but this was my first loose leaf tea ever and it was honestly gross. This would not be a good introductory tea if you've never had loose leaf tea. I'm glad you all do sample packages because I can sample teas until I find one that will suit my taste buds. I decided not to rate it badly because I'm a newbie to teas and your company seems to have it together but I just wanted to write this for those people who are hopping from like Tazo tea bags to organic - don't do start off with this one lol

    Nice Alternative to my Regular Japanese Green Teas

    Posted by john hughes on 21st Feb 2018

    This tea is absolutely worth having around for variety! It is less sweet and nuttier tea, with a dry finish, as compared with my staples of Sencha and Gyokuro. The only reason I didn't rate it with 5 stars is because I reserve that for my very favorite teas. I recommend this to any green tea enthusiast!

    Good Tea

    Posted by Greg Eldridge on 18th Aug 2017

    This tea is a lot like a Sencha. Nice color. Very smooth. Maybe a little chalky after taste. It is the same price as Sencha. For the same money I prefer the Sencha. However, this is a quality tea that I would be happy to drink on a daily basis. Definitely worth ordering a sample and checking it out for yourself.

    I mostly drink Japanese green teas. This (to me) has that kelpy, ocean flavor that I love, but is still a pleasant change from my normal habits. It's light and fresh. I brew this one at lower temperatures (say, 160 degrees) and resteep 2 - 3 times. It was a while ago that I had the Woojeon (the other Korean tea), but the Sejak has a lighter, brighter taste and feel compared with it. They're both excellent and I'll definitely buy again.

    This was my first time trying a Korean tea, and i bought the sampler. I brewed mine a bit stronger then the directions said but man it is becoming one of my favorites. I easily brewed 3 cups off the one serving i made and each cup brought out interesting and delicious notes of the tea. I usually prefer dragon well when I'm drinking green tea but this has a bit less astringency in my opinion and is much smoother. I plan on ordering lots more as my current stash of green teas get depleted.

    Very nice!

    Posted by Kara on 10th Dec 2015

    This is my first time sampling a Korean green tea and the best way I can describe the Sejak variety is that it tastes somewhere between a Chinese green and a Japanese green. At the very end of the cup you can catch a wisp of a salty, oceanic flavor. Lovely!

    Very pretty color and amazing taste

    Posted by Unknown on 23rd Apr 2015

    I ordered a sample of Korea Sejak and was completely blown away how delicious and light in taste it was. Came back to order a full size because this is so far my favorite tea! And the color of the tea is the prettiest I have even seen.

    Great every day green tea.

    Posted by Alison on 16th Apr 2015

    I have enjoyed both Korean teas from Arbor Teas - the Sejak and the Woojeon. If price is a limiting factor for you, go with the Sejak and you will be happy, if you are looking for a nice, SenCha-like green tea. I prefer to the Woojeon, as it seems similar, but a bit stronger, and slightly more vegetal / astringent to me, but it is significantly more expensive. However, I'm still giving it 5 leaves, because Sejak is a great tea. I'd like to very respectfully disagree with the reviewer who likened this tea to bancha. To me, this tea tastes nothing like bancha, which has more of a roasted, heavier flavor, in my opinion.

    My new favorite green tea.

    Posted by S.R. Payne on 10th Jan 2015

    I'm very pleased to write a glowing review of this wonderful tea. One of the greatest problems that I have with green teas seems to be finding one that has that 'all around' pleasure of it's consumption thing going for it. this one has it all. Some green teas have absolutely no flavor at all and are never purchased again. Some have an over powering vegetal or oceanic smell and taste about them and are never purchased again. This one I will be purchasing again. This is one that I very highly recommend to you. Before I had even finished pouring my steeping water over the tea leaves I could pick up a very pleasant, sweet vegetal fragrance. Not over powering, just very sweet. Upon first taste, I found the first green tea that is well worth staying with. It is not as strong in smell or taste as some Japanese teas which at times can be a bit much. This one leaves a very pleasing sweet after taste. As a matter of fact, I am having a cup of this wonderful offering from Korea as I write this review. The estate that grows this tea has a winning product on their hands. One of the best green teas I have thus far tasted. I hope that you agree....Steve.

    deeply satisfying

    Posted by wally jasper on 29th Aug 2014

    Sejak Korean tea is a delicious Japanese-style green tea, full bodied, kind of vegetal and, as the previous reviewer noted, very reminiscent of sencha. I'm wary of buying food products from Japan since the Fukushima disaster, so was delighted to see this high quality Korean tea with a deeply satisfying Japanese taste profile. I'm so grateful to Arbor Teas for offering this and the Korean Woojean teas.

    If You Like Sencha/Bancha

    Posted by Andy on 25th Feb 2014

    A very nice alternative to Japanese green teas. Tastes and looks very much like Sencha. Very nice. I will buy this one again.
