I got an order this week. Tried Bird Rock - Chirinos. It was so delicious. Now I'm planning an all light roast order. I thought I was a dark roast person, but I just had bad acidic light roast and really added cream to dark. That light roast was black and so delicious.
I am not familiar with all these roasters so I don't really know what their whole beans are like. That said, my impression is that this frozen coffee certainly is superior to any K-Cup but not in the same league with the same coffee in a good pourover. YMMV, of course.
