Unsweetened soy drink, water and milk test: Garu Teacher Seoritae
In short
Garu Teacher Seoritae is an unsweetened powdered soy drink made with Korean black soybeans and sea salt. I mixed it with water and milk for busy mornings and while camping; it was deeply nutty and dissolved well in cold water, though its near-unsweetened flavor may feel unfamiliar at first.

Because I often skip breakfast, I tried Garu Teacher Seoritae as something easy to have on hand. I wanted to keep up my protein intake while eating black soybeans regularly. This article reflects my experience using a product that was provided to me.
What form does it come in, and what are the ingredients?
Soaking, boiling, and grinding soybeans yourself takes quite a bit of work, but with this product, you can add water to the powder and drink it like soy milk. The simple preparation was what I found most convenient.
The ingredients are 99.3% Korean seoritae (black soybeans) and 0.7% Korean solar sea salt. It is presented as a product without added sugar, flavorings, or sweeteners, and its short ingredient list stood out to me.
How sweet and nutty is it?
When I drank it, it was not sweet; it tasted mild but intensely nutty. It felt a little different from the ready-made soy milk I have tried. Its near-unsweetened flavor may feel unfamiliar at first, but I think it would suit people who enjoy the natural taste of seoritae.
Was it convenient to store and use while camping?
Because it is a powder that can be stored at room temperature, it was easy to keep. I thought it would be useful to bring along when traveling or camping, and it was indeed convenient to quickly mix and drink in place of breakfast at a campsite.
How much should you add to water, and does it dissolve in cold water?
I added about two included scoops to 150–180 ml of water, stirred it well, and drank it. It dissolved fairly well even in cold water, which was convenient when I needed to prepare a drink quickly.
It is presented as a product that uses whole soybeans. I could actually see particles of black soybean skin in the mixed drink.
What was it like as a breakfast substitute?
I drank it because I wanted an easy way to eat black soybeans and get protein. Rather than expecting it to prevent or treat illness, I considered it part of my diet.
On days when breakfast was hard to manage, one glass felt more filling than I expected. I also liked that it reduced the time I would otherwise spend boiling eggs or preparing a meal.
The product information quoted in the original post lists about 12 g of protein and about 130 kcal per serving. However, the original post does not specify the weight of powder used per serving or which liquid those figures apply to.
How does the taste change when mixed with milk?
It was good mixed with water, but it tasted smoother when mixed with milk. Since I usually like milk, I found it nuttier and tastier with milk.
You can also adjust the thickness and use it as a base for kongguksu (cold soybean noodle soup), a salad dressing, or a yogurt topping. From my experience, what stayed with me was how easy it was to mix and drink, along with its unsweetened nuttiness.
