Why does soda from a bottle or can into a glass of ice create a mountain of foam, but soda fountain soda does not?
It has to do with the temperature differential. The CO2 cools the water, which in turn cools the mixed drink. If the bottle or can is refrigerated, there will be less foam.
The Short Answer
It has to do with the temperature differential. The CO2 cools the water, which in turn cools the mixed drink. If the bottle or can is refrigerated, there will be less foam.
