Task: Sentiment Analysis
Input (English): 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.
