Every once in a while a kindergartner will come home a little down. Yes, the poor thing had a bad day at school. So in Japan one way that might be fixed is by breaking into the six pack of winter beer for children! Too funny!!
The end of the commercial says、
こどもの のみもの winter スンガリア
Which basically means that it is a winter sangria drink of children. There are not many details given about alcohol content.
