Thanks, -Dave My numbers: Brix 20.3 pH 3.66 TA 5.9 YAN 148 mg N/L I will be adding sugar to bring the Brix up to 23, and a little bit of acid to bring the TA up to 6.4 October 21, 2019 at 1:48 pm #2436 AnonymousInactive Using last years chemicals, these numbers are from 2 1/2 days cold soak Brix 20.4 pH 3.57 TA 6.0 YAN 126 Grapes smelled and tasted of mould, started fermentation last night.

The thing that I found is difference between my Brix reading and the above two posts. My Brix showed 22.5. pH was 3.5. I wonder what others had. You must be logged in to reply to this topic.
