With the yeast oxygen scavenging method, I have seen in some graphs that pH drops a bit but can't seem to find this right now. Is there a general rule of thumb in how much pH would drop after using YOS @ 2g/gal for 30minutes? I can generally nail my mash pH right off the bat with lactic acid additions but not sure how this will be impacted by YOS method first ie getting lower than anticipated mash pH. EDIT: water temp during YOS treatment is ~100F
