The terminology is subjective, and the idea that something someone somewhere on the internet characterizes as “woodsy” necessarily is defective is going to result in a lot of false rejects.
Woodsy, grassy, and floral all have pretty collective meanings in the coffee world. Sure, some random person can claim something is grassy when its not... but if you're asking a coffee professional, it's not that subjective.
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.
