No dude, just like fine dining, wine tasting and other things there are definitely margins of wide preference but there's also very clear tastes that are objectionable to anyone who tastes them and is aware of them. You can have a preference of reds or whites but anyone who's trained can taste when a wine has oxidsized or turned sour and those are pretty objective statements of fact. Overroasted coffee is definitely a thing if you've done coffee tastings and actually know what coffee tastes like and how the roasting process affects flavor profiles.
