Have you ever picked up red ginseng or gift cards for Chuseok, only to find them still sitting untouched in a corner of your parents’ fridge?
Instead of an expensive, flashy gift, something you can enjoy every morning — a good korean soybean milk pick — often ends up meaning more in the long run.
We took a closer look at two soy milk varieties made with Korean yakkong and seoritae.
In this article, we compare two korean soybean milk picks — Kookmin Yakkong Soy Milk GOLD and Kookmin Seoritae Soy Milk PLUS+ — by ingredients, manufacturing method, and nutrition facts.
Both are made with 100% Korean soybeans and postbiotic ingredients, making them a thoughtful choice for a Chuseok holiday gift.
Why Is Korean Soybean Milk a Good Choice for Chuseok Gifts?
Because it’s something you can drink every day, it doesn’t feel like a special-occasion-only item that gets set aside.
Korean soybean milk refers to soy milk made from domestically grown soybeans, so the origin and ingredients are easy to verify.
As Chuseok approaches, many of us start wondering what to give our parents or family.
A gift enjoyed just once during the holiday is nice,
but plenty of people are looking for something they can keep using regularly at breakfast or as a snack.
That’s why we want to introduce a korean soybean milk pick for anyone who cares about where their food comes from.
✅ You can drink it every day, so it stays useful well beyond the holiday
✅ Made with 100% Korean soybeans, so the origin is easy to verify
✅ Available in two flavors, so you can choose based on personal taste
Kookmin Yakkong Soy Milk GOLD, made with Korean yakkong, and Kookmin Seoritae Soy Milk PLUS+, made with Korean seoritae,
let you enjoy the distinct character of each bean — making them a well-rounded Chuseok gift for the whole family.
How Do the Ingredients Differ Between Yakkong Soy Milk GOLD and Seoritae Soy Milk PLUS+?
The two products start out different at the bean itself.
Kookmin Yakkong Soy Milk GOLD and Kookmin Seoritae Soy Milk PLUS+ are korean soybean milk picks made with Korean yakkong and premium-grade Korean seoritae, respectively.
Kookmin Yakkong Soy Milk GOLD uses Korean yakkong (seomoktae) — a small, firm black soybean.
Kookmin Seoritae Soy Milk PLUS+, on the other hand, is made with carefully selected, 100% premium-grade Korean seoritae.
| Category | Kookmin Yakkong Soy Milk GOLD | Kookmin Seoritae Soy Milk PLUS+ |
|---|---|---|
| Bean used | Korean yakkong (seomoktae) | Premium-grade Korean seoritae |
| Pure soy milk ratio | 99.76% | 99.76% |
| Soybean solids content | 8% or more | 7.5% or more |
| Manufacturing method | 4-Free (no added sugar, coloring, flavoring, or stabilizers) | Stone-ground whole soy milk |
Both products are made with non-GMO Korean soybeans, which is why we recommend them as korean soybean milk picks for anyone who values transparency about origin.
When it’s a Chuseok gift for family, it makes sense to check every single ingredient a little more carefully than usual.
What Postbiotics Are in Kookmin Yakkong Soy Milk GOLD?
Each pack of Kookmin Yakkong Soy Milk GOLD contains 10 billion cells of KM2 postbiotics.
KM2 postbiotics is an ingredient developed from Lactiplantibacillus plantarum KM2, a patented strain discovered in-house by Kookmin Bio.
It’s made with 99.76% pure soy milk and at least 8% soybean solids,
and it’s a 4-Free soy milk with no added sugar, coloring, flavoring, or stabilizers.
Rather than masking the bean with sweetness or added aroma, it lets the rich, nutty flavor of yakkong come through on its own.
So if you prefer the plain, natural taste of soybeans over a sweeter soy milk, this is the one for you.
It’s rich enough that the bottom can settle into a thicker texture if you don’t shake it,
but it still goes down smoothly and tastes gently mellow.
We recommend giving it a good shake before drinking.
Research on KM2 has continued steadily, including patents registered in Korea and Japan and publications in SCI journals.
The ingredient is also listed on the U.S. FDA’s New Dietary Ingredient notification list (NDI No. 1378).
What sets this soy milk apart is that it goes beyond soybeans alone, incorporating an ingredient Kookmin Bio has researched for years.
⚠ Even products containing postbiotics are regular foods, not health functional foods, and cannot claim to prevent or treat any specific disease.

How Is Kookmin Seoritae Soy Milk PLUS+ Made?
Seoritae Soy Milk PLUS+ is made differently from typical soy milk, which extracts the soy liquid and strains out the solids.
Stone-ground whole soy milk is a method that finely grinds the skin and flesh of the bean together, rather than straining out only the liquid.
By using the skin and okara (soybean pulp) as well, this method aims to retain more of the nutrients naturally found in seoritae.
It’s made with 99.76% pure soy milk and at least 7.5% soybean solids,
and each pack (180ml) contains 8g of protein and 4g of dietary fiber.
If you enjoy nutty seoritae soy milk and like to check nutrition facts closely, this one is worth comparing.
✅ Stone-ground whole soy milk grinds skin and flesh together to help retain nutrients
✅ Each 180ml pack contains 8g of protein and 4g of dietary fiber
✅ A balanced flavor that’s easy to enjoy even if you’re used to unsweetened soy milk
What Makes KMU01 a Distinctive Ingredient?
Beyond soybeans, Kookmin Seoritae Soy Milk PLUS+ also blends in ingredients researched by Kookmin Bio.
It includes KM2 postbiotics along with Kookmin Polyfermenticus Culture Complex KMU01.
What stands out is that Kookmin Bio didn’t stop at sourcing good beans — they also packed their own research know-how into every pack.
Seoritae Soy Milk PLUS+ has a slightly lighter taste compared to Yakkong Soy Milk GOLD,
but its balanced flavor makes it especially appealing if you’re already used to unsweetened soy milk.
What Kind of Facility Is It Produced In?
Kookmin Bio’s soy milk is produced at the Kookmin Bio Practical Application Center, a HACCP-certified facility.
Since it’s a product the whole family drinks every day, ingredient selection, manufacturing, and packaging are all carefully managed.
If you’re choosing a Chuseok gift for your parents or family, it’s worth checking the production environment, not just the product lineup.
Yakkong Soy Milk or Seoritae Soy Milk — Which Should You Choose?
Both are korean soybean milk, but each has its own distinct appeal.
Yakkong Soy Milk GOLD’s appeal lies in its rich, mellow yakkong flavor combined with KM2 postbiotics.
Seoritae Soy Milk PLUS+’s appeal comes from premium-grade Korean seoritae, stone-ground into whole soy milk.
If it’s hard to pick just one, you can also put together a set with both products.
Everyone can choose based on their own taste, making it a great Chuseok gift for parents and the whole family alike.
Each pack is easy to grab and go, so it also works well for a busy morning, after a workout, or as an afternoon snack.
