Coffee Master is their star product. I first saw in a cafe that you can replace the milk with their Coffee Master oat milk. I tried it and it really clicked! The oatmeal flavor is so fragrant and it doesn't overpower the coffee flavor. I was immediately attracted to it hahaha. I later went to their Tmall flagship store to buy it and drank it myself, and found that drinking it on its own was also very delicious, and it was really addictive! Sometimes I also use it to soak cereal for breakfast. And I see that their oat milk contains dietary fiber, which is really rare! I look specifically at this when choosing oat milk. Oat milk with dietary fiber has much higher nutritional value.
