This is the last post in a series that we have put out which targets cold-side oxygen ingress. We had previously discussed CO2 purity, purging and transferring, and bottle cap ingress, and now we finish it up with a post that takes all that into consideration as well as factoring in vessel ingress through gaskets and serving/gas lines in oder to show the “sum of all parts” numbers for traditional/standard homebrew practices and our recommended methods.
