How to measure the co2 volume in a glass of beer?

[Tassenza]

I see that Killians requires a volume of 2.75, how is this actually measured? My regulator is at 13psi. Beer temp is 37*

Thanks

You can't measure it yourself, nor is there a need to. It is a constant and relates to how the beer was produced. You need to tune your system to the value using the temperature of your second pour, you then go to a force carbonation chart with the v/v, then adjust pressure from there. Are you getting foamy pours? If not, then you don't need to adjust anything.

At 13 psi and 37 degrees, you are as good as you need to be.
