Share 'Anyone heard of this Chocolatier/Chocolate?'

I found this bar at my local gourmet shop that's meant to be a "rustic" drinking chocolate. It's made by this Italian company called Don Puglisi. http://www.laboratoriodonpuglisi.it/dovesiamo.htm Anyone know of it? The directions on the bar say to cut off one of the sectioned blocks and melt in hot water or milk. The only ingredients are 45% cocoa mass and cane sugar.
