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.

This tea has NO flavor, tastes like dust It "looks" like quality -- pretty package -- but it's no good. Lipton regular Pekoe is farrr superior.

We had the same issue with this product. Half the flat was improperly sealed, and resulted in an expired food issue.  But you can spot the unsafe jars because they have dried up & turned solid, resulting in a different sound when shaken.  Also, when opened, these "bad" jars are mounded up in the middle and have a rotten smell.  It may be that the product was frozen in shipping, and the expansion caused the seal to break.  I have requested a refund from Amazon.  Our baby did love this meal though - it was like Thanksgiving dinner.  The ones that were still edible were delicious, and are one of his favorite foods.
