I adjusted the high acid in a batch of wine by using potbicarb. I dropped the TA .3%. I notice a distinct color change from the brilliant color normally attributed to Baco Noir to a purplish hue not as brilliant. It has now been several months. I have read that the color of wine will change due to PH. Is this what has happened? I also had to adjust my chardonnay. I wonder what the impact on that will be? thanks Sarge
Yes, rise in pH will move the red color more into the blue part of the spectrum and some brilliance will be lost. In white wines it's not really an issue.

Sarge - I also grow Baco. I think you're fortunate to still have a purple color in your Baco. I find that when the pH goes much above 3.5 the wine takes on a brownish color. What is the pH and TA in your Baco after adjustment?
