I have a PJS EN PRIMEUR Kit thats 3 years old .I replaced the old yeast,And It fermented fine.Now I'm at stage 2 Secondary Fermentation.it calls to add Pectinase that came with the kit .I'm not sure if it's still good or should I add Pectic Enzyme instead that I just purchased.If I use the Pectic how much should I add.Thanks in advance
