Rich matcha soy milk powder: Garu Seonsaeng Jeju Matcha

I received this product for review. I had seen Garu Seonsaeng's powdered soy milk on the Olive Young online mall and was curious to try it. Of the three flavors—Jeju Matcha, seoritae (black soybean), and mugwort—I chose Jeju Matcha because it suited my usual tastes.

What is in the box and what are the nutrition facts per sachet?

Drinkable Raw Soy Milk Jeju Matcha is a plant-based soy milk combining Jeju-grown matcha and soy milk. Each 20g sachet contained 85 kcal and 4.2g of protein. The package stated a shelf life of 12 months from the manufacturing date, and the product I received also had plenty of time remaining.

The ingredients were listed as Korean soybeans, matcha, solar salt, and unrefined raw sugar. When I opened the box, there were eight individually wrapped soy milk sachets inside.

At first, I wondered whether it might taste better mixed with milk, but I wanted to know what the soy milk itself tasted like, so I decided to mix it with water. One sachet felt fairly substantial in my hand.

How did I mix it with hot water?

To mix the powder well, I emptied one sachet into a glass and poured in water boiled in an electric kettle. I wanted to try it rich, so I filled only about half of a small glass. I estimated the water at about 120ml, but did not measure it exactly.

The box said it could be made hot or cold. This time, I wanted a warm drink, so I chose hot water; after stirring thoroughly, I had a deep-green matcha soy milk.

Was the soy milk and matcha flavor rich even when mixed with water?

Rather than drinking the matcha soy milk on its own, I wanted to enjoy it as a snack, so I took out three cookies I had left at home.

Perhaps because I used so little water, it was richer than I expected. From the first sip, the soy milk flavor was clear enough to tell immediately that it was soy milk, with the bitter note of Jeju matcha added to it. It suited my taste, since I usually like both soy milk and matcha.

The sweet cookies paired well with the rich, slightly bitter matcha soy milk. I had it as a snack at home over the weekend.

Where was it listed for purchase?

As of Jun 30, 2026, when the original post was written, it was described as a limited-sale product available only through Olive Better and the Olive Young online mall. There was also notice of a special promotion at Olive Better from Jul 10 to 19, but no specific price was listed.

This time, I mixed it only with hot water. Next time, I would like to try it with cold milk, or make cup bingsu (shaved ice) with a little extra Jeju matcha powder and milk. After drinking the Jeju Matcha flavor, I also became curious about the seoritae and mugwort flavors.
