Isn't the bubbling/foaming due to the CO2 coming out of soda water?

Yes, but the rate is related to turbulence which generally scales with velocity. Try to fill a drink glass with high pressure soda coming through a straw would just make a fountain of foam. Poor it slowly and there will be minimal foam. To speed filling without increasing velocity widen the stream.

Somewhat related, some measure the quality of a tea kettle by the height you can pour a laminar flow into a tea cup.
