Not one member of my family, including me, like these extremely salty, much too strong a BQ taste to order more.  I purchased them on a recuring basis and i wish to cancel now.  I have received only one shipment. Cancel further shipments.  Not to our taste at all. These are Lowery pork rinds.

I am only drinking it, so it won't be wasted, and I have to rotate it with a Coffee People product, so I remember why I like coffee.  It is really wan. The strongest flavor profile is tin.  I love creme caramel and am a huge WP fan, but the flavor strenth and consistancy of this coffee does not impress. Choose another - you won't be sorry you did.

Ex Input:
We don't drink much coffee, and less decaf, but we have guests who do and so we like to keep some ground decaf in the freezer for when they visit. Everybody has been pleased with the Melitta. Nobody has complained about the taste, and plenty of folks have asked for second cups so they weren't just being politely quiet. We got the first sample free through the Vine program but I would buy it in the future.
