You guys are not going to believe this. I received something like this in C on TYO-CPH. After dinner I asked for some champagne and the guy brought this mini-bottle. I didn't get a chance to look at it before rejecting it and asking for the Henriot. The background of the label was white or cream colored. So maybe they were serving this in Y?

Pre-departure they were serving Drappier. Used to often serve NF.

I flew Y on CPH-ARN yesterday and noticed that the label of the NF had changed.
