    I recently bought a pH meter, and I am finding it to be very useful!

    But one quick question about using it on actively fermenting wine:
    Do I need to worry about CO2 affecting my reading?

    I seems like I remember reading somewhere that CO2 should be removed by heating/agitation before trying to meter if the juice is fermenting. However I just read the pH tutorial on this site <How To Understand ph, and Take A Reading> and it doesn't mention anything about CO2.

    Is it standard operating procedure to try to eliminate CO2 before taking a pH reading, or not?

    during fermentation the CO2 can form carbolic acid, this will distort the ph reading and it will be invalid. wait until wine has cleared and been degassed before taking any useful ph readings.
