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 hot chocolate is pretty blah. Not very chocolatey and certainly not very strong. It's not the fault of the Keurig -- the Cafe Escapes Dark Chocolate is way better.

Best Bit-O-Honey I have ever eaten. I have always bought this product at a local grocery store and it was always hard, I figured it was suppose to be that way. But after eating the box I bought here I now know better; the candy was soft and delicious. I plan to continue buying Bit-O-Honey from here.
