🌱 It's not easy to put together a proper breakfast every morning, so I keep looking for things I can grab quickly. I like soy milk in general, but a lot of the store-bought kinds have sugar or additives in them, so I've started paying closer attention to the ingredient list.

This time I tried Garu Seonsaeng Drinkable Raw Soy Milk Yakkong 99.3, a black soybean soy milk you mix up fresh in whatever amount you need. I was curious, so I gave it a try myself. 😊

What is in Garu Seonsaeng Yakkong 99.3?

Just being soy milk doesn't make it good — what matters more is which ingredients were used.

🌱 Looking at the product, it uses only 99.3% Korean black soybeans and 0.7% Korean sea salt. It was impressive that there's no sugar, flavoring, emulsifiers, or preservatives — just the taste of the raw ingredients.

If you prefer unsweetened soy milk or care about the ingredients, I think you'd be pretty satisfied. It also seemed like a good option for anyone specifically looking for Korean-grown soybean or Korean black soybean soy milk products.

Does the soy milk powder mix in cold water?

The most important thing in the morning is how convenient it is.

💧 I put the powder in a cup and just poured water over it, and it mixed better than I expected. With a shaker it blends even more smoothly, and even in a regular cup there weren't big clumps — I could drink it just fine.

You can make just the amount you need on the spot, so there's less worry about leftovers, and storage is convenient too. If you've been curious about soy milk powder, powdered soy milk, or instant soy milk products compared to carton soy milk, I think you'll find this pretty usable.

How does Garu Seonsaeng black soybean soy milk taste?

It wasn't sweet, and I actually liked that even more.

🥛 If you're used to sweet soy milk, it might taste a bit plain at first. But as you keep drinking, the natural nuttiness of the black soybeans comes through, and with no artificial sweetness, it was easy to drink without feeling heavy.

I had a simple glass before heading to work in the morning, and it sat well and worked fine as a snack too. If you're looking for unsweetened soy milk or a healthy snack, I think the taste would satisfy you.
