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.

These Backyard BBQ Kettle Chips were a great deal with the promo code.  It was nice to have a larger size bag.  Some Kettle Chips in the grocery store are only about 5 ounces and we polish them off in one family lunch!  They arrived fresh and were not in crumbles as some other chips from Amazon Grocery have been.  Great flavor and All Natural!

My little ones love seaweed and rice and this seaweed did not disappoint. other brands are too oily or salty or not enough.  This one though is just right. I would be buying it again... and again.
