Calpis Welch's Crush Muscat

Calpis Welch's Crush Muscat is a carbonated, muscat-grape-flovored drink sold by Calpis in Japan. It's quite unique in that it contains 20% real muscat grape juice; most drinks only have a few percent of juice contained inside.

Taste
The first impression I got from the drink was that it was a very fruity drink with a strong muscat flavor. The drink contains sweeteners and is very sweet; personally, I find it a little too sweet. There is some fizz to the drink, but not much.
Overall, I would describe it as "sweetened carbonated muscat grape juice".
