If you love super dark, rich, bold and thick flavored coffee then this is the coffee for you...with one problem.  Personally I love coffee that embodies everything I just said.  I love esspresso and the like.  To find a K-cup that is this bold even on the 10 oz. setting is great...but there is that problem again...  It smells, tastes, and leaves the after taste of burnt urine!  Like someone torched a public restroom and mopped the floor with coffee, then packaged it. Yum!  There are other dark, bold k-cups out there that have a better smell, flavor and does not have a nasty after taste. You may not believe me, and that is fine, but get a sample pack before going for the 24, you'll thank me later. Try the Green Mountain Coffee Extra Bold Sumatran Reserve K-Cups. Better all around cup of coffee.

I'm far more of a tea drinker than a coffee drinker, but I can't start the day without a cup or three of coffee. Plus, I'm not really awake until I smell the coffee brewing - just not morning without it.  I tend to buy more affordable (e.g., supermarket type brands) of coffee so I can splurge on tea. So this was a real treat - outstanding aroma just opening the bag, and even better when brewing. Delightfully smooth taste, and highly drinkable black (the only way I drink coffee or tea).  My only complaint is opening the bag. Based on what other reviewers stated, I opened it over a plastic bin so it would catch any spills. Very glad I did - an appreciable amount was spilled when I cut into the bag. I decanted it into an air-tight container. I've had this problem with other vacuum packed coffee, but the very fine grind of the Melitta made it even more of a problem.  Still, not enough of a problem to warrant taking away a rating star. This makes a wonderful cup of coffee!
