[Q]: 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.
[A]: Smooth and tasty and an absolute dream come true for those who enjoy bold dark roasts...


[Q]: I have a pure breed GSD and had problems for years with upset stomach, eating grass and throwing up bile in the morning and then would not eat as her stomach was too upset.  It finally dawned on me that due to throwing up bile in the am was that the food was not staying with her.  I even tried feeding her before going to bed at night and still did not work.  I tried Evo and I could not believe the change.  She does not get us up at night to go outside.  She was having 3-4 bowel movements every day and now she has 1 or sometimes 2.  I have had her on the Evo large bites for almost a year now and she has not been sick once.  It is the higher protein in this food that stays with her longer and has made all of our lives so much better.  Thank you, thank you EVO!!!
[A]: OMG, What a life saver


[Q]: First of all, I have owned a Keurig for about 4 years now, and I've tried lot's of coffee.  During that time, I have had an occasion k cup that didn't function correctly and loaded the brew with grounds.  I probably should have returned these before I bothered to open the second box.  Since I drink my coffee from a thermal cup, I can tell you that taking that last drink to find your mouth full of coffee grounds stinks.  I have had to throw out at least 6 cups of coffee.  Its a bit like Russian Roulette, and I've started straining it after I brew it.  I know that its not my brewer because it is not happening with the Green Mountain, Timothy's or Tully's that I also use.  The good cups are a bit weak for my taste, but the flavor is ok.  Definitely prefer not to waste $'s on a product with a manufacturing defect.
