I thought this coffee was really horrible. Had one cup and will throw the rest away because it can't be returned.

Ex Input:
I was expecting a very high quality coffee but this wasn't quite it. It's a lot stronger than I was expecting due to the serving size printed on the label. It was pretty strong even for me and I like strong coffee.  However, I adjusted the amount of coffee and after a couple of tries I got a nice pot. It has good, but not great flavor. Definitely better than Folgers and the like but not top tier quality.  I recommend this to anyone looking for something a step up from Folgers.

We have tried many of the different hot cocoa k-cups...everything always tasted so watered down, even when using the smallest setting on the machine.  However, this brand...even at the medium cup setting, tasted fantastic.  I highly recommend Grove Square.  I haven't tried any of their other products, but I would be inclined to now based on this cocoa.
