Although I've only been able to try three of Caribou's k cup blends (Mahogany as well as <a href="http://www.amazon.com/gp/product/B00474OR8G">Caribou Coffee, Caribou Blend, K-Cup Portion Pack for Keurig K-Cup Brewers, 24-Count</a> and <a href="http://www.amazon.com/gp/product/B00474VPLI">Caribou Coffee, Daybreak Morning Blend, K-Cup Portion Pack for Keurig K-Cup Brewers, 24-Count</a>), I've found that Caribou consistently produces the highest quality k cups.  They are head and shoulders above their competitors like Green Mountain and Van Houtte.  I should mention that Caribou's Daybreak blend is far and away my favorite k cup flavor of the 20 or so I've been able to sample so far.  But I enjoy a flavorful medium roast.  My boyfriend, on the other hand, prefers an extra bold dark roast.  After our favorable experience with the Caribou brand before, we picked up a box of this coffee and hoped that it would be a great choice for a dark blend.  Let me just say that Mahogany is full of smokey delicious flavor.  It's quite strong and dark, but there is no rancid bitterness or acidity that accompanies a lot of the dark roasts.  This coffee packs a powerful punch.  Although that isn't normally my thing, I can enjoy a cup of this with milk and a bit of sweetener.  My boyfriend adores it, though, and it has become a staple blend for him.  I will still drink this on occasion, but it's a bit too potent for me.  I think this is the best dark roast I've had the chance to try.
Smooth and tasty and an absolute dream come true for those who enjoy bold dark roasts...

This tastes terrible...  Like putting aritficial sweetener in already sweet hot chocolate.  The best I have tried so far is Swiss Miss Hot Chocolate K-Cups.  Don't think they are sold on Amazon yet...
Too much artificial sweetner

This is the best Keurig K-Cup hot chocolate you can buy. I've tried others, but will never buy any other brand again.

THE BEST
