Takara Plum CANCHUCHI

I grabbed this drink at a 7-11 in Beijing for about 7 RMB (about $1 USD). It's sour and tastes like sour apple even thought it's supposed to be plum flavor. I guess it's supposed to be some sort of plum wine, but with 4% alcohol it's more like a bad wine cooler. It's carbonated, weak, and overall not very tasty.
