Managing total package oxygen (TPO) can be a challenge for beer producers looking to grow their output. TPO is the total concentration of oxygen (O2) present in packaged beer at the time of packaging. When beer comes into contact with air, it begins to oxidize — and too much oxygen can negatively affect the beer’s flavor.
The ultimate goal is to reduce the amount of oxygen allowed in during packaging to prevent oxidation and maintain product quality and taste. However, this can be easier said than done, especially if you’re transitioning from a smaller-scale production with manual processes to greater throughput with increased automation.
