WebMar 18, 2014 · Knowing the TPO not only helps you determine exactly how much oxygen is trapped in the container and can react with the beer, but it also allows you to calculate the headspace contribution to the package oxygen concentration. The headspace oxygen of a package is the TPO minus the dissolved O 2: Headspace O 2 = TPO – unshaken dO 2 WebJun 12, 2012 · Simply put, TPO is defined as all of the oxygen in the package: headspace and liquid. We can also just say that TPO is all of the oxygen available to react with beer in a package. In order to get an accurate TPO, we need to know four things: dO 2, headspace volume, liquid volume, and temperature. We’ll cover the importance of volume and ...
