Ok, here's my question. I bought some whole bean coffee from a major, national coffee house (don't know if I can say their actual name but anyway). I bought the espresso roast bold flavor. When I pulled a shot it tasted burnt - like someone had a lighter and lite a coffee bean on fire and let it burn for a while, grounded it up and then put it in a espresso machine. I'm not the best at wording things but that's what it tasted like. Why did it taste this way? Can I get some professonial feed back on this please, I'd appreciate it.
