I am planning to make a wine using Welch's 100% Grape Juice with Calcium ! Is the calcium problem here !

  • Could you write more details, what are you worried about exactly, etc. – Philippe Jul 15 '19 at 15:44
  • Well I was worried about the Calcium in the Welch grape juice ... But Mr Brewchez said no worries from the Calcium but I have to consider the preservatives because it needs more yeast .. I don't know how much yeast I need to add ! – user13886 Jul 15 '19 at 16:23
  • Feel free to edit your original question to ask for more information about yeast or post another question if you like. – Philippe Jul 15 '19 at 17:21

Calcium is not going to be an issue. The sorbate as a preservative is likely going to be an issue. Pitch more yeast than you think you need to overcome the preservative.

    If you're not adding any additional sugar I'd use at least two packs of yeast. Three wouldn't hurt. Some yeast nutrient would be a good idea too. You know that table grapes like Concord Grapes make lousy wine right? Most grape juice (certainly Welch's) is made from Concord Grapes. – brewchez Jul 16 '19 at 12:25
  • I believe in that .. it'll be lousy wine .. but I wonder why in YouTube some guys said it's perfect! That's why I wanna just try it – user13886 Jul 16 '19 at 12:31
  • Cool. Let us know how it turns out. I am not curious enough to try it but I am curious. Love it. Good luck. – brewchez Jul 17 '19 at 12:43
  • If people say that wine made from Welch is perfect, ask them what other wines they like... it should be closer to lousy (or nasty) than perfect ;-) – Philippe Jul 17 '19 at 18:05
