When I heated it up, it became mildly sweet and very tasty. I thought it was like Yamahai in that it lost its sharpness and became rounder. It is just right to go from hot to lukewarm.
I think it's refreshing when cold and gets sweeter as the temperature rises. It felt thick when pouring. The aftertaste is not sweet, so you can keep drinking it and not get tired of it.
