After a few of these inverse purges I felt like I may have put my brew in danger of oxygen exposure. This beer is far from expelling CO2 as it is 30+ days old. What do you guys think? Do you do this all the time or did I make a huge mistake?
I feel like I have heard someone say they foil for lagering to avoid the vacuum problems but there is probably still CO2 expulsion to combat that..
Nothing to worry about. Oxygenation would be if you splashed around your beer post ferm, just removing an airlock isnt really doing anything. Should be all good.
