A Moustache in Japan

I had Pepsi White yesterday, the new Yogurt Pepsi drink. It didn’t really taste like yogurt, but, like practically every drink here, tasted like a liquid version of some solid food I am used to.  It was pretty good, but I cannot yet place it.  I will drink more to let you know what it turns out to be.  I wonder if this is coming out in America, too?
