Vintage Cognac?

[dalziel001]

My friend claims that he has two bottles of 'Vintage' cognac. I don't believe him, as they appear to me to be the following:

1x bottle Courvoisier 3 star Luxe
1x bottle Remy Martin Fine Champagne VSOP

I know very little about cognac, but aren't these regular product lines that one finds in supermarkets, or are there circumstances where they could be considered 'vintage'?
