Ex Input:
Wow, I did a lot of reading trying to make a good decision on a K-cup hot chocolate, and of course taste is something that is very subjective.  If you read all the reviews on every product you'll discover that nothing gets past everyone and maintains a perfectly spotless reputation.  So I decided that even with some bad reviews I'd try this one since it has a lot of good reviews.  I'm just going to say that there are some real hot chocolate connoisseurs writing reviews in this thread.  Some discerning reviewers say it has a slight taste of sugar substitute, or some such thing.  All I can tell you is I must have under-achieving taste buds because all I can taste is yummy hot chocolate.  My family burned through the first box and I just ordered two more.  If you don't like this I feel sorry for you. Better to have numb taste buds I guess.  Enjoy.

Maybe my tastebuds are different but I bought this at a local healthfood store and I'm not completely sold on it.  I tried it in my tea and it did leave me w/ an aftertaste...just like most sweetners. *shrugs*

Ex Input:
I prefer the "extra bold" coffees, so this one really lacking on the flavor.  It's fairly weak, at the smallest cup setting its drinkable, but I won't be buying it again.  I'd recommend the Timothy's World Coffee, Rainforest Decaf Espresso instead.
