Temple YR 1975 UL http://www.ajevonline.org/content/26/4/195.abstract AB Pectic enzyme treatment gave some time savings in color development. At least 20% less fermentation time was required to obtain the same color prior to pressing when pressing was done early (48 to 72 hours). At a given skin contact time, less total phenols were extracted in the control. Wine quality was not lowered by the enzyme treatment.
