I recently switched from aerating my batches with an air filter to using pure O2 via Bernzomatic bottles from Home Depot. I got the regulator from Austin Homebrew Supply. The general consensus from the research I have done suggests that 60 seconds at 1 liter per minute is an ideal starting point but without any sort of gauge I have no way to know exactly how much O2 I am feeding from the Bernzomatic when fully opened up. I was curious how long folks using this method are hitting a 5-gallon batch. Thanks in advance.
