The shipment was Prime but arrived in 5 days instead of 2. I love dark french roast coffee, but, this coffee tasted burnt and additionally, the flavor had overtones of trash Indonesian.  Not a pleasant experience.

I am just passing along the 5-star rating from our three Miniature Schnauzers. This stuff is a big hit at our house. We give them each an easy to digest kibble that's good for them and put a tablespoon of Pot Pie on top. No more turned up noses now - they wolf it all down. Be sure to mix it up real good before serving.
