Miserable? Is it really that miserable to suggest that flavors are not that subjective? I’m not saying they’re absolute, I’m just saying that when you taste a lot of anything (coffee, wine, tea, chocolate, whatever) you get better at identifying flavors. And certain flavors are purely due to roasting a certain way. If you overroast coffee, you get burnt flavors. Now some people might like burnt flavors, just like some people might like grassy flavors. That doesn’t mean they aren’t generally considered to be defects in a roast though.
