“Bordeaux Superior” is seen on labels and restaurant menu lists.  It has the “appellation Controlee” guarantee.  It sounds like it is a better (superior) Bordeaux wine. The “superior” that is guaranteed by law, is that the wine is one or two percent  higher in alcohol strength, than a regular Bordeaux wine.  Some wineries make use of this designation and some don’t bother.

Once again here is just a collection of labels showing this designation.
