Alma Negra M Blend

A mystery wine, perhaps what the M stands for on the front label?  The only hint from the winemaker is a composition of the signature grapes from Mendoza. Pretty big hint as that generally means Malbec, but there could be clever partners of Cab and other red varietals lurking here to give a dark, brooding expression of wine, hence the dark almost sinister label.  Have fun with this one!
