Quick carbonation question

[RichardM]

I have a simple question since I’m new to this. I understand setting pressure & temp to achieve carbonation. Let’s say I do a set it and forget it method of 12 psi at 38 deg to get about a 2.5 vol co2. The carbonation is fine, but the pour is too fast at 12psi and causes foam. If I lower the pressure to 8psi, will the beer stay at 2.5 volume and just pour slower or will it drop down in volume as well?

Thanks.

From what I understand, temp and pressure dictate your carbonation level, as you said. Serving line length dictates pour speed. If you decrease pressure at the same temp, you will also decrease carbonation level. Sounds like you need a longer serving line to provide more resistance and slow the pour. Use this
