That doesn’t match my experience at all. Beans make a huge difference. Unless you like French or Italian roast espresso blends of course. Yes, you have to have the right grind, temperature, roast profile, pressure and temperature profile during extraction, but all that is just a skill. Beans are the difference between Starbucks and awesome. Mysore coffee is why I roast my own. I can get them when they’re available and have roast them when I want them.
