I have gotten fairly into coffee but I struggle to independently pick up these subtle notes. I'll take a sip, struggle to put any concrete words on the taste, and then read the tasting notes and (honestly) think "ah of course, yes I definitely get that". But I'm sure it's all just the power of suggestion.

(An exception is some Ethiopian beans which have an unmistakable blueberry aroma and taste that they are famous for.)

I've stopped worrying too much about "advancing" past that level. Now I just buy the coffee, read the notes, enjoy experiencing the sensations that have been placed in my head. Is it "connoisseurship"? Is it a placebo? Who cares, it's fun!
