Quick question. If you were going to add yeast nutrient to a red wine, at what sg level would you add it and how much to a 6 gallon kit? Any different for a white wine kit? thanks, Ron
I would only add nutrient if I started to smell an odd odor from my fermentation. ( caused by yeast stress ) I have had a couple of wines do this. The time to add it would be towards the end of fermentation but while it's still fairly active SG 1.020 and add as Scotty has stated ( per direction on packet/bottle ) sometimes only a half dose may be required.
Some kits have it added up front, others like Mosti have you add it towards the end as described above. It can't hurt if your making a wine from scratch of sorts. Keeping yeast happy and well fed is always preferred over stressed yeast!
