[Physics] What makes the continuous stream of bubbles from a single spot when you pour champagne/highly carbonated beverages?

I just poured a glass and often they just keep coming from a single spot for a very long time.

Dust or scratches in the glass provide what are referred to as nucleation sites where bubbles of dissolved gas can precipitate out of solution. It's hard for dissolved gases to escape a liquid without a nucleation site that allows bubbles to form. This is why boiling chips are used in a chemistry lab, to prevent liquids from becoming superheated and prone to explosion.
