Marabou Premium 86% cocoa

This is the big brother of Marabou Premium 70% cocoa, and it does have a bolder cocoa flavor.  This seems to help the overall effect -- I am still tasting a metallic aspect, but it is much less than with the 70% bar. The extra richness also is adding an earthiness and nuttiness to the flavor, making it a more interesting bar. 6.5
