Why I looked for an oat drink on busy mornings

When getting ready for work overlapped with taking care of the children, I often left without breakfast. On days I started on an empty stomach, I found it hard to concentrate in the morning and kept thinking about snacks, so I looked for something convenient to have.

I usually like oat drinks, so Garu Seonsaeng Oat Drink caught my attention. I thought simply adding water and mixing it would suit busy mornings.

I had previously tried to make ona-o (overnight oats) regularly, but the preparation felt cumbersome.

Soaking oats the night before, refrigerating them, and preparing toppings meant I gave up after only a few days. Drinking a lot of dairy can sometimes make me feel bloated, so I began looking into plant-based drinks made with oats.

What stood out about the ingredients and storage?

In the ingredient description, I noticed that it uses Canadian oats.

It says it uses oats, sea salt, and unrefined raw sugar, without emulsifiers, artificial flavorings, or preservatives. After reading this, I thought it seemed less burdensome to have with my children, too.

Being able to store it at room temperature was convenient, too. I had been concerned about needing to finish liquid products quickly after opening them and about refrigerator space, but this powdered product was easy to store.

How I made it without preparing the night before

I poured water into a cup, added the oat drink powder, mixed it well, and drank it. There was no need to soak, blend, or strain oats separately, so preparation was simple.

Unlike preparing ona-o (overnight oats), I liked that I could make it and have it straight away in the morning.

How was it different mixed with water and coffee?

I mostly mixed it with water and drank it like an oat beverage. I also tried mixing it with coffee in an oat latte style, and it went together better than I expected.

When I mixed it a little thicker, I could also enjoy it with a texture like oatmeal porridge. Prepared this way, I felt it was enough as a meal replacement.

How did the powdered drink taste, and how filling was it?

At first, I expected a powdered product to taste bland. Once I tried it, though, the nuttiness was rich and the flavor felt quite deep.
