      Post the results of your chemistry on the 2018 Chardonnay here.
      I re-calibrated my pH meter and rechecked my sample + did a YAN test, pH came out lower (3.62 instead of 3.68), everything else the same. Below are my revised numbers:

      Press-run: Brix 23.6 pH 3.62, TA 5.0
      Free-run: Brix 23.4, pH 3.62, TA 5.3
      YAN: 70 mg N/L
      I plan on added 2 g/L of tartaric acid. No water addition planned.

      I will do a YAN Sunday evening once back from the Saanich crush.
