The name of this coffee is Mahogany, in my mind a deep rich brown. The coffee flavor is deep and rich, and the color is dark brown. It is delicious.

This comes in a case of 24 so I bought one can locally before ordering the large amount.  Good move!  I have 3 cats and none of them would eat it. This review is for the mature gourmet beef entree. Haven't tried the other favors yet.
