I am making a white from concentrate. I will backsweeten to obtain a semi sweet wine. She is allergic to most berries, plums, red grapes, and all citrus fruit as well as citric acid. Most White grapes and apples don't bother her. The ph is 4.2 with everything added except the acid blend.
2 cans (11.5 oz) Welch's 100% frozen grape concentrate
1-1/4 lbs granulated sugar
2 tsp acid blend
1 tsp pectic enzyme
1 tsp yeast nutrient
