In short
Garu Seonsaeng Yakkong Soy Milk 99.3 is an instant soy milk powder made of 99.3% Korean black soybeans (yakkong) and 0.7% Korean sea salt. Mixed with water, Garu Seonsaeng Yakkong Soy Milk tasted clean and lightly nutty; mixed with milk it turned much smoother and richer, and a shaker bottle had it ready to drink right away. It is not as thick as soy milk ground fresh from beans at home, but for anyone who likes unsweetened soybean flavor it is an easy everyday option.

I usually love soy milk so much that I soak and grind beans at home to make it myself. But the process of preparing the beans, soaking them, and grinding them finely in a blender takes way more effort than you'd think.

So I went looking for an easier soy milk option and came across Garu Seonsaeng Yakkong Soy Milk. What I tried this time was the Instant Raw Soy Milk Yakkong 99.3.

I usually like the nutty flavor of beans, similar to black soybean soy milk, so let me honestly share what I thought after trying it.
What is in Garu Seonsaeng Yakkong Soy Milk? 99.3% Korean black soybeans

The first thing I check when trying a new soy milk is the ingredients. Garu Seonsaeng Yakkong Soy Milk is made of 99.3% Korean black soybeans and 0.7% Korean sea salt.
When I make soy milk at home, I like the taste of the bean itself, so I prefer a plain flavor over a sweet one.

This product also felt different from sugary soy milks. The nutty, plain flavor of the black soybean was front and center, so if you like bean flavor like I do, it should suit your taste well.
How to mix the soy milk powder in a shaker bottle

Since it's a powder, the way you drink it was simpler than I expected. All you have to do is add the right amount to water and mix it well.

I tried putting it in a shaker bottle and shaking it. When I make soy milk myself, I have to prepare the beans in advance, but with this, I could make it the moment I wanted to drink it, which was convenient.


It seemed especially good for mornings when time is tight and you want to prepare a simple glass quickly.
What Garu Seonsaeng Yakkong Soy Milk tastes like: unsweetened and nutty

What I was most curious about was the taste! Compared to the black soybean soy milk I usually drink, it felt a little different. Rather than a sweet soy milk, the natural nutty flavor of the bean came through more.

Since I normally make plain soy milk at home too, I personally liked this flavor.

If you're expecting a strongly sweet soy milk, this might taste a bit plain.
But if you like the nutty flavor of beans, it should be an easy, comfortable drink.
Water or milk: which mix tastes better?

At first I mixed it with water and drank it plain. The nutty flavor of the black soybean felt clean and crisp.

On days I wanted something softer, I mixed it with milk, and it added a much smoother, richer, nuttier feel than the water version.
So I decided I'd mix it simply with water in the mornings, and use milk on days I wanted to enjoy it a bit richer and smoother.
Other uses: bean broth, oatmeal and yogurt

Since it's a powder, I also liked that you don't have to drink it as just a single glass — it's versatile.

You can make it a bit thicker and use it like kongmul (bean milk),

and it was also good mixed into oatmeal or yogurt. If you usually like black soybean soy milk or kongmul, it could be fun to adjust the concentration to your taste like this.
Garu Seonsaeng Yakkong Soy Milk vs homemade black soybean milk

Honestly, it's not exactly the same as soy milk made by grinding beans yourself at home. Homemade soy milk has a heavier, freshly-ground flavor that comes through a bit more intensely.

But the advantage of Garu Seonsaeng is that it cuts out the hassle of soaking and grinding beans, and you can mix it up whenever you need it. Even for someone like me who usually makes soy milk from scratch, it seemed like a good, easy option for busy days.
Is Garu Seonsaeng Yakkong Soy Milk worth buying?

For someone like me who loves soy milk and drinks bean-based drinks often enough to make them from scratch, this product was a pretty different experience. What stood out most was the 99.3% Korean black soybean ingredient makeup,
and I personally liked being able to taste the unsweetened, plain nuttiness of the bean that I enjoy. On busy mornings I'll mix it simply with water,

and on days I want it a bit smoother, I'll mix it with milk instead.

If you like black soybean soy milk or prefer a plain taste over sweet soy milk, Garu Seonsaeng Yakkong Soy Milk might be worth checking out as an easy, convenient option.
