I've never ordered a regular coffee at a Starbucks, Caribou, or Dunn Brothers that didn't taste burnt to the point of being undrinkable. I prefer gas station coffee.
I have, however, been gifted bags of freshly ground beans from all three of those places. When I brew it at home, it tastes wonderful. But I don't believe I've ever spent money on a bag of coffee shop coffee.
Normally, I'm a Folger's drinker. I like their version of French Roast, 100% Columbian, and Gourmet Supreme. I also like their Regular Blend. Our local grocery rotates them on sale, and I buy the cheapest.
A generous amount of Coffee Mate Hazelnut non-dairy creamer, and I'm a happy guy.
