Hi there,
I have 5 buckets (6 gallons each) of Zinfandel wine juice that I picked up from California Concentrates back in September. I basically just let it set and ferment with the natural yeast. I usually rack it to a carboy/degass/add tanin & raisins but this time around I just let it go. Can I still add tanin and raisins this late in the process? If so, would you please give me a suggested workflow? Thank you.
