Lately I've been looking for a breakfast substitute that's easy to prepare but not too sweet, so I tried Garuseonsaeng Seoritae's [Drinkable Oat Drink] this time 😊

So I thought it would suit people who prefer the natural nuttiness of ingredients over strongly sweet drinks! It's also a good recommendation for anyone managing a diet who wants a snack that's not too sweet, or a simple meal substitute to have at home 👏🏻

Powder instead of liquid: how do you store it?

Another thing I liked was that it's a powder, not a liquid product! With liquid products you have to finish them quickly once opened, so you always have to think about storage and timing. But with this, you can just scoop out what you need and make it fresh each time, so it's a lot more relaxed to use 👏🏻

The best-before date was June 29, 2027, so there's plenty of time, and for storage you just keep it in a cool place away from direct sunlight! The zipper on the package closes well too, so it was easy to keep and take small amounts out little by little.

A measuring spoon comes in the pouch

It even comes with a dedicated spoon, so there's no need to measure separately! The handle is long, so when using it your hands don't get messy and it's easy to reach deep into the powder, and after using it you can just tuck it right back into the pouch!

How does the unsweetened oat drink taste?

What I liked most of all was that it's an unsweetened type! Since it's not a product that adds sugar for sweetness, it was easy to taste the natural nutty flavor of the oats.

It's said to be oat powder made from oats grown in pristine Canada, ground whole including the hull, so if you like the plain, nutty flavor unique to oats, this is easy to enjoy without hesitation ✨

How to mix it: 2 scoops in 180ml of water

📍How to drink the [Drinkable Oat Drink]: Add 2 scoops with the dedicated spoon, about 30g, to 180ml of water and mix well — that's it! 🥛 True to its name, it's really a mix-and-drink type, so there's no hassle of soaking, grinding, or straining oats.

It dissolved better than expected even in cold water, so it was great to make right away on mornings when I was short on time! 🙊 It can be enjoyed cold or warm, so you can choose depending on your preference.

I made it right away and drank it, and it had a much thicker feel than I expected! I thought it would just be a light oat drink, but once mixed with water it had a fairly rich, smooth texture. 🙊 As I drank it, I found myself thinking, 'How can this be so rich when it's just a powder?' haha 😂 It was nutty and plain, and since the sweetness wasn't strong, it actually suited my taste better.

Other ways to use it: overnight oats, oat porridge, smoothies

I think this would be very useful for anyone looking for a plain breakfast. It's good just drinking it like a beverage, but it's also great to use when making overnight oats 😌 Normally overnight oats need to be prepped the night before, but using [Garuseonsaeng Seoritae Oat Drink] takes care of that instantly!

On days you want something warm, making it thicker with hot water and using it like oatmeal porridge would also be good! It seems useful when you want a simple but filling breakfast in the morning.

There's also a way to blend it with fruit to make a simple oat drink smoothie, and a way to use it with coffee to enjoy as a nutty drink, so it didn't feel like there was only one way to eat it.

Is Garu Seonsaeng Oat Drink Unsweet worth it?

In conclusion, Garuseonsaeng Seoritae's Drinkable Oat Drink was quite a practical product for anyone who wants to easily incorporate oats into their diet. 🌾 In particular, it seems like it would have many uses for people looking for unsweetened oatmeal, overnight oats, an easy breakfast, or a plain snack.

Above all, when I actually tried it, the thick, rich texture was more appealing than I expected — it's not just something you mix with water and drink. Being able to have it cold or warm, and being able to prepare it in 10 seconds with just water, was definitely convenient on busy days 😋
