I have a kit wine that I cold stabilized and I think it was likely a mistake because it seems a bit dull now. pH is about 3.6 so was thinking that it might need a bit of acid so I got an acid test kit. If I go by the color change it’s coming out to be about 0.56g/l but I have read that the pH being 8.2 is a bit more reliable so I also checked the pH when the color changed and it was only 7.2. If I add more NaOH to get to 8.2 the TA comes out to be 7.1g/l which is pretty good.
Well, which one do I trust? I have repeated the test several times with similar results for each and I also bought new NaOH as well as pH buffer solutions to see if those were off.
As it stands I have no confidence in either method which makes me hesitant to try to make all grape wine where things will not be balanced for me.
