On busy mornings when I am getting ready for work, it is often hard to fit in a meal, so many days end with just a cup of coffee. This time, I received Garu Seonsaeng Oat Drink and tried it as a breakfast substitute.
What oats and ingredients does it use?
Garu Seonsaeng Oat Drink is said to use Canadian oats. Since I usually pay attention to getting dietary fiber, I was interested in being able to drink oats so conveniently.
It was introduced as containing the whole oat, including the outer layer, so that you can consume beta-glucan and dietary fiber together. The ingredients are oats, sea salt, and unrefined raw sugar, and it is said to contain no emulsifiers, artificial flavorings, or preservatives.
How easy is it to prepare on a busy morning?
Preparation was simple: I just put the powder in a cup and added water. When I made it myself, it took less than 10 seconds. There was no need to soak, blend, or strain oats, so it was easy to have a cup while getting ready for work.
It was good for a light drink not only in the morning, but also on a hungry afternoon or after a workout. Compared with ona-o (overnight oats), which I used to prepare the night before, I found it convenient that I could make it right when I wanted to drink it.
Does it dissolve well in water? What are the taste and texture like?
When I mixed it with water, it blended more smoothly than I expected. It dissolved cleanly without feeling clumpy, and the finished drink was a soft beige color.
On the first sip, I noticed the nutty aroma of grains first. It had a subtle scent like freshly roasted grains, and went down smoothly. Although it is powdered, its flavor felt just as rich as the ready-to-drink oat beverages I have tried.
The sweetness was mild rather than excessive. To my taste, it did not have an artificial sweetness, and it was easy enough to drink even on an empty stomach in the morning. It was good cold too, but I personally thought the nutty flavor came through best when it was mixed with lightly chilled water.
What did I like about it as a breakfast substitute?
What I liked was how quickly it could be prepared and how rich its nutty taste remained even when mixed with water. It suited me for a simple cup before work or when I wanted a light afternoon snack. Its plain oat flavor also suited my taste.
