Assessing what you know is a good exercise.
Of course, you might not know what you don’t know, but you can usually make an accurate judgement through a gut feeling when thinking about your peers.
Some of your peers seem to know a little bit about every wine. Snippets, sound bites, info-bits. They can pull something out about any wine, any time. This is a valuable talent.
Then others seem to know a ton about a few key regions, varieties, and producers. They can’t stop themselves when telling the stories. They find deep information that it seems nobody else knows. This, too, is a valuable talent.
Which are you? Are you trying to be both? Is that your goal? What is the best path?
All good questions to ask yourself.
