Aaron,
Glad I could help, but it still may not be absolutely definitive that it's the cultivar.
The Bordeaux family has very variable leaves due to culture and intensity of disease (FMV). I have yet to find any actual documented pictures of the individual cultivars, Petite Negri, Petite Aubique, Negronne, Violet de Bordeaux, Beer's Black or even Vista, it seems that they have been sold and traded with all these names, interchangeably.
I Hope that this comment does not add to the confusion. Good Luck.
