Garuseonsaeng Seoritae Oat Drink Unsweetened lets you enjoy the nutty, plain flavor of oats in their natural form.
Is unsweetened oat drink powder bland?
Honestly, I'm not a big fan of oat flavor, and I usually go for sweeter drinks, so I was a little worried when I ordered this. Especially with the unsweetened version, I had a bias that it would taste flat and bland..!
But guess what? It was way nuttier and more mellow than expected, and it surprisingly suited my taste haha. The most shocking part was that even I, with my sweet tooth, was enjoying it!
The package arrived sturdy and neatly wrapped!
A friendly instruction sheet, the oat drink powder packet, and even a measuring spoon!
Ingredients and nutrition: what's in Garuseonsaeng Seoritae Oat Drink
What caught my eye while checking out the product was that it kept the natural flavor of the ingredients without any additives.
According to the guide, it contains no sugar, emulsifiers, artificial flavoring, or preservatives at all, using only oats and sea salt to bring out the oats' natural nutty flavor. The nutrition info shows 119kcal per 30g, with 20.7g of carbs, 4g of protein, and 4.7g of fiber. Sugar is listed as 0g!
It also uses Canadian oats, and includes the whole oat husk so you get the beta-glucan and fiber packed into the oats too haha.
Ready in 10 seconds: how to mix the oat drink
Garuseonsaeng Seoritae Oat Drink comes in powder form, so you can just scoop out as much as you want and pour in water for an easy drink.
I liked that there's no hassle of soaking, grinding, or straining oats — you can just make it on the spot. Especially on mornings when I want to eat something but don't have time to prepare, this kind of convenience was pretty welcome.
One spoonful was plenty for me. If you want it stronger, you can just adjust the amount, so it's easy to suit your mood day to day.
Oat drink in water vs in milk: the taste difference
I tried it with water first, and it was much better than I expected!! Since it's unsweetened, I thought it would have no flavor at all, but there was a subtle nutty taste that made it clean and easy to drink.
Out of curiosity, I tried it with both water and milk.
Personally, I liked it more mixed with milk. The added smoothness and nuttiness definitely made the flavor richer!?
Also, since it's a powder product, I thought I'd need to finish it quickly after opening, but it was convenient that I could scoop out just what I needed and keep even the last spoonful fresh. Not taking up much space in the fridge was a nice bonus too!
Final verdict on Garuseonsaeng Seoritae Oat Drink Unsweetened
I've dropped my bias that unsweetened means tasteless..! If you've hesitated because you thought unsweetened oat drinks would be bland like I did, you might be surprised by how nutty it actually tastes.
I enjoyed it with water for its natural nutty taste, but my preference is still a spoonful in milk — that's more my style, so I've been drinking it that way regularly haha. This is something I'll keep using as a simple breakfast or a light snack when I'm hungry :)
