The pH shouldn’t change much, if at all, during bulk aging, unless your wine goes through MLF. In that case, your pH would actually be expected to increase.Does PH drop during bulk aging a red wine ( about 1 year old)? My Ph started at 3.65 a year ago and now it is 3.45.
Thanks
Dissolved CO2 lowers pH, so when it is released it would raise pH by a little bit. That does not explain why the pH would drop from 3.65 to 3.45.What does decrease during bulk aging, is the amount of CO2 dissolved in your wine, which allows for increasingly accurate pH measurements, as the presence of CO2 in your wine distorts the pH readings. Perhaps you’ve seen the effects of that, as opposed to actual pH changes, do you think this could be the case?
