Why do champagne bubbles all originate from the same place in the glass?

Question

I’m drinking out of a round rocks glass and noticed all the bubbles are coming from a few bubble geysers; this is instead of soda and sparkling water where the bubbles seem to be more random and chaotic. Why is this?

Answer 1

That’s a key bubble formation point, there is probably some cavity or dirt there, which bubble can grow on
