I seem to find myself pressing at 2, 2.5 Brix (mostly drive by when I
have time, etc.). Haven't had a problem yet. The fermentation
shouldn't be that aggressive at this point. Lum states in his great
manual that color extraction reaches a high around 8 days of contact.
After that day the intensity drops off and the tannin extraction
continues to trend upward. I don't know how many days you have been
fermenting but that may help with your decision.

HTH,
