Osulloc Green Tea Guide: Which Flavors Are Worth Buying?
The Jeju Island Tea Craze in Seoul
I was standing inside the Olive Young near Gangnam Station last Tuesday, watching a group of international tourists stare blankly at a wall of pastel tea boxes. Osulloc is undoubtedly the king of Korean tea, harvested straight from their sprawling organic fields on Jeju Island. If you walk into any high-end department store or duty-free shop in Seoul, you will see their sleek packaging everywhere. But when you are standing in front of a shelf with twenty different varieties—ranging from pure traditional green tea leaves to wild fruity concoctions that smell like candy—it is easy to feel overwhelmed.
As someone who lives in Seoul and drinks Osulloc tea almost every afternoon, I have tried nearly every box in their lineup. Some are absolute world-class blends that I stock up on regularly, while others rely a bit too heavily on synthetic aromas. In this osulloc green tea guide, I am breaking down the absolute best teas and edible matcha treats from the brand so you know exactly what is worth your money before you buy.
Top Osulloc Teas and Treats Reviewed
1. Osulloc Sejak (Jeju Organic Green Tea)
If you want to taste pure Korean green tea culture without any added fruit or floral flavorings, Sejak is the gold standard. It is made from young tea leaves harvested around May Day on Jeju Island, using a traditional method that combines both steaming and roasting.
Taste & Texture: The flavor profile is amazingly smooth, mild, and nutty. Unlike standard Japanese sencha, which often carries an intense seaweed-like umami note, or cheap commercial tea bags that hit you with harsh astringency, Sejak is gentle. It has a subtle sweetness at the back of your throat with almost zero bitterness, even if you accidentally steep it a little too long in warm water.
How Koreans Drink It: Older Koreans and tea enthusiasts brew loose-leaf Sejak in small ceramic teapots using water cooled down to around 70°C (158°F). However, the pyramid tea bag version is extremely popular for office workers who want a high-quality cup at their desk without the fuss. It pairs brilliantly with light rice cakes like garaetteok or plain biscuits.
2. Osulloc Wedding Green Tea
This is easily Osulloc's most famous blended tea, and it is almost always the top recommendation for first-time buyers visiting Korea. It blends organic green tea leaves with sweet muscat grape, marigold petals, and rose blossoms.
Taste & Texture: The moment you open the foil pouch, a massive wave of floral grape aroma hits the room. It smells almost like a luxurious grape candy or a glass of chilled white wine. On the palate, the green tea base grounds the sweet fruitiness, keeping it from feeling sticky or artificial. The astringency is incredibly low—much lighter than a standard Earl Grey or English Breakfast.
How Koreans Drink It: This is a massive favorite as a gift during wedding season or housewarming parties. While it tastes wonderful hot, it is exceptional when cold-brewed in the fridge overnight during hot Seoul summers. Serve it over ice in a tall glass, and it feels like drinking a high-end mocktail.
3. Osulloc Moon Walk (Pear & Honey Tea)
Moon Walk is a unique blend made from post-fermented tea leaves mixed with Korean pear (bae) and sweet honey flavorings. Korean pears are famous for being crisp, juicy, and immensely sweet, and Osulloc captured that essence brilliantly in this box.
Taste & Texture: The brewed tea has a deep amber color and a rich, honeyed pear aroma that fills the entire kitchen. The taste is round, warm, and naturally sweet. The fermentation gives the tea base a slightly earthy depth similar to a light black tea, which balances the sugary pear aroma. It feels cozy and soothing on cold autumn evenings.
How Koreans Drink It: Koreans love reaching for Moon Walk late at night after a heavy dinner of Korean barbecue (samgyeopsal). The refreshing pear note cuts through grease surprisingly well, and because the caffeine content feels quite low compared to pure green tea, it will not keep you awake all night.
4. Osulloc Jeju Canola Honey & Hallabong Tea
Hallabong is Jeju Island's famous premium citrus fruit, similar to a sweet mandarin or satsuma with a distinct top knob. This blend mixes green tea with dried Hallabong peel and local canola flower honey.
Taste & Texture: It strikes a wonderful balance between bright citrus acidity and smooth honey sweetness. If you find plain green tea too grassy, this citrus kick completely masks the vegetable notes. The intensity is bright and zesty, reminiscent of a refined, less sugary version of traditional Korean yuja-cha (citron tea).
How Koreans Drink It: This is a staple winter pick-me-up. Whenever people catch a winter cold in Seoul, drinking a steaming mug of Hallabong tea is considered the ultimate comfort ritual. It also makes a great alternative to morning coffee if you suffer from a sensitive stomach.
5. Osulloc Green Tea Milk Spread & Green Tea Wafers
You cannot write an osulloc green tea guide without talking about their edible snack line. You will often spot these near the checkout counters at Olive Young, GS25, or large supermarkets like E-Mart.
Taste & Texture: The Green Tea Milk Spread is essentially a green tea version of Nutella—thick, lush, creamy, and heavily sweet with a strong matcha bite. The Green Tea Wafers feature crisp, delicate layers filled with a vibrant, bitter-sweet green tea cream. Compared to standard green tea KitKats, Osulloc's wafers have a much stronger roasted tea flavor and far less waxiness.
How Koreans Drink/Eat It: The milk spread is slathered generously onto warm toasted shokupan (milk bread) or used as a dip for plain pretzels. The wafers are eaten alongside a hot mug of plain Americano or unflavored green tea to balance the sweetness.

FAQ
Is Osulloc green tea high in caffeine?
Most pure Osulloc green teas like Sejak contain moderate caffeine levels—roughly 20 to 30 mg per cup, which is about one-third the caffeine of a standard cup of brewed coffee. The fruit and herbal blended varieties generally have even less caffeine per serving.
What makes Osulloc tea different from standard green tea?
Osulloc grows its tea in volcanic ash soil on Jeju Island, which is rich in organic minerals. The combination of Jeju's humid climate, ocean breeze, and unique processing methods (combining both steaming and pan-firing) yields a tea with lower astringency and a much smoother, nuttier taste profile.
Where is the cheapest place to buy Osulloc tea in Korea?
While you can buy boxes at Olive Young or convenience stores, prices vary by store. The best deals in Seoul are usually found at large hypermarkets like E-Mart or Lotte Mart during promotional sales, or at duty-free shops if you are purchasing multi-box bundles before your flight home. Typical box prices range around 15,000 to 25,000 won depending on the tea grade and package size.
