High pH and High TA

[Johny99]

Not a grape I know, but please calibrate your pH meter, verify you are accounting for temperature, then measure it again. If there is CO2, boil it out first as it will give you an off reading. I say this because I almost added acid to a must based on pH last week, I'd calibrated the weekend before and was lazy. I decided to recalibrate and the reading dropped 0.2something. I checked 4 wines and three standards to be sure. Calibration matters, and this is on a $1,000+ lab instrument.

Just a thought before you adjust.
