What is Garuseonsaeng Seoritae Baektae 99.3 powdered soy milk?
This is Garuseonsaeng Seoritae's soy milk I drink every morning — powdered soy milk made from Korean-grown white soybeans, Baektae 99.3.
I've been drinking Garuseonsaeng Seoritae's baektae soy milk every morning lately! I used to buy a soy milk maker and go through a whole phase of making soup and warm soy milk in winter, but soaking and grinding the beans was surprisingly a lot of work, so after a few uses it's just been sitting asleep in my cabinet.. Buying carton soy milk isn't great either since the trash piles up every time, but not drinking anything at all feels wrong when I want something before heading out to exercise in the morning! So I've been mixing both.

So this time I tried the baektae soy milk you can easily mix from powder!
I've been the type to carefully check ingredient labels lately! I filter out anything with emulsifiers, but Garuseonsaeng Seoritae's mixable raw soy milk says no emulsifiers added, so it passed right away!


Ingredients: 99.3% Korean white soybeans and 0.7% sea salt
First I checked the ingredients!
I'm the type to check the ingredient label first on anything I eat! Garuseonsaeng Seoritae Baektae 99.3 is made of 99.3% Korean white soybeans and 0.7% Korean sea salt. No sugar added, so it's a sugar-free soy milk — don't expect a sweet taste — but I like that the ingredient list is simple and sugar-free! I've been trying to drink regular soy milk unsweetened too.

At first I wondered if a powder type would taste okay, but I'd tried black soybean powder before and it turned out simpler than expected. Being a pouch type makes it easy to store too — just scoop out what you need and mix with water, which makes mornings a lot easier.

I usually drink a glass before heading out to exercise in the morning — just keep a bottle ready, add water and powder, and mix. No soaking or grinding beans in a soy milk maker, so this convenience is why I keep reaching for it.

A lot of soy milk on the market is sweetened or packed with various ingredients, which gets tiring to choose between, but Garuseonsaeng Seoritae's raw soy milk has a simple composition I like — it's basically just beans and sea salt, which suits me since I'm someone who checks ingredients before picking a product.

Does the powder dissolve in cold water? Stirring it into 200ml
Garuseonsaeng Seoritae's mixable raw soy milk dissolved easily even in cold water. I usually just make it in a regular glass at home — add water, add powder, stir — simple, and you don't even need a shaker, a spoon works fine.
At first I wasn't sure about the concentration, so I mixed the recommended amount, and after that I adjusted little by little to my preferred thickness. I don't like it too watery, so I use about 200ml of water??

Since it dissolves well in water there's no stress about it haha, and it's easy to drink so I've been pairing it with breakfast!

On days I want it thick I add a bit less water, and on days I want something lighter I add a bit more! For mornings, drinking it on the lighter, more diluted side suited my taste better than something heavy. Best of all, mornings can be a hassle when you have to prep something to eat, but this just needs mixing with water, so I reach for it often.
Comparing days I drink it versus not, I did notice a slight difference in how hungry I felt during the morning — I've read that protein keeps you fuller longer than plain carbs. But more than anything, there's a satisfying feeling of having had a glass of soybeans, which is why it keeps becoming part of my morning routine haha.

What does Garuseonsaeng Seoritae Baektae 99.3 taste like?
This is what I was most curious about, and it's nuttier and more savory than I expected. If you're used to sweet soy milk, it might taste a bit plain at first. I've always liked soybean powder and soy milk, so I actually liked this plain flavor. It's less like an artificially sweetened taste and more like the natural nutty flavor of the soybean itself!? And honestly, the bean flavor is strong enough that you could make kongguksu (cold soy milk noodle soup) with it!
Making kongguksu (chilled soybean noodle soup) at home with the powder
These days a bowl of kongguksu at a restaurant can be surprisingly pricey, but if you just boil noodles at home and mix the baektae soy milk a bit stronger, you can get that kongguksu feel pretty easily.
Next time I'll try adding cucumber and sesame seeds and make it properly at home. I still have a soy milk maker but barely use it these days — the powdered, mixable soy milk suits me much better. Especially for something you want to have every single morning, simple prep wins out over complicated in the long run, and Garuseonsaeng Seoritae's baektae soy milk is convenient in that sense!

How much protein is in one serving?
I also checked the nutrition info — based on the labeled serving size, protein content is 12g, which matters since I've been trying to hit my daily protein target lately, so this raw soy milk is a must! It's great for a glass before exercising in the morning or on days when meal timing is awkward, and best of all there's no burden of having to make it fresh every time.
If you prefer plain, nutty soybean flavor over sweet soy milk and want a sugar-free soy milk you can easily mix at home, a powdered product like Garuseonsaeng Seoritae's baektae soy milk is worth looking into!
