How exactly should I show off my new-found expertise?

I want this to be a question other people could use in the event they stumble upon some knowledge as I have. Basically, my girlfriend is from Shaoxing, China, the home of Chinese yellow wine, for you wine-o’s reading I keep bumping into the term “tastes like a Sherry”, my wine enthusiast friend agreed with that conclusion as well.

In any event, after going to g/f’s hometown 4–5 times I’m starting to become a bit of a foreign expert on the drinking of the stuff, and really enjoy it. I want to share my knowledge of this yummy drink and interesting culture with the world and would like a few suggestions on how exactly to go about it. What say you?
