My batch of CA Zinfandel is progressing nicely, but I have a problem with my PH. I tested last night, and found that while my acid is good (.70) my sulfite is good (40ppm) my PH is out of conbtrol at 3.8!
What are my options? Add more tartaric and then cold stabilize? or add an acid reducing chemical?
Any help would be appreciated, Best, PB
