I just started a batch of Pomegranate wine. The Juice I used said clearly on the label that 8 fluid oz had 31 grams of sugar that means that one fluid ounce would have 3.875 grams of sugar in it. I put 120 fluid OZ of Pomegranate juice and 8 oz of water in a 1 gallon Jug. based on 3.875 grams of sugar in 1 fluid ounce of the POM there should be a total of 465 grams of sugar in my 1 gallon of juice and 8 oz of water. that would be just a little over a Lb of sugar in my 1 gallon batch. (actual total 1 Lb and .4 oz). The charts I have say that 1 Lb of sugar in 1 gallon of water will produce an SG of about 1.040 with a PA of about 5% but when I took a reading of the actual juice I got a reading of 1.052 or a PA of 7% Am I doing something wrong or is there something else I am missing???
