I bought some Welch's white grape juice which is Niagara juice. A small amount of it added to my wine got the flavor I was looking for. I made Niagara wine several times before and always had to reduce the acid before bottling but never as much as this time. Reducing the acid also reduced the flavor drastically. I already bottled 6 gallons so when I open one of those bottles I will just add some juice. I am going to add it to the other 6 gallons, along with stabilizer, before bottling.
Thanks for the good, quick help. Now get off your computers and go drink some wine!
