This is a really dark roast coffee which I usually like.  It has a bite to it but the bold/complex flavors and aroma weren't quite there by my taste.  I tried it in a coffee press, drip and a steam coffee machine that we have at the office but couldn't find that sweet spot that would make it work for me.  I'm a little bias because I picked up <a href="http://www.amazon.com/gp/product/B001EO5PB0">Jeremiah's Pick Coffee Colombia Supremo Decaf Whole Bean Coffee, 10-Ounce Bags (Pack of 3)</a> at about the same time to compare and absolutely love Jeremiah's.

I tried this gum after Trident cinnamon became hard to find a couple of years ago.  (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.)  I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back.  It does last a long, long, long, time.  Unfortunatley, as other reviewers noted, it has become very hard to find in stores.  Trident cinnamon is everywhere but now I don't want it.  Amazon saves the day again.

I enjoyed this coffee for it's smooth flavor that wasn't extremely strong. It's definitely better than most brands you find in the grocery store. I would recommend this to someone interested in a solid cup of coffee.
