Whenever I get a drip coffee or pour over from a cafe, it usually has some light bubbles that linger well after pouring. It seems like the coffee is thicker somehow. What is this and why don't I get this nearly as much at home using pour over and also high quality coffees?

I can't remember where I read this, but the gist was these bubbles are a result of pouring speed/height, for example, when pouring from carafe to cup. Do you brew into a carafe at home?

These bubbles, what's in them, the impact of pouring speed/height, etc., seems to be more of interest in tea brewing.
