The refractive index of the juice was 26 degrees Brix and the density was 1.11 g/ml. According to Pambianchi's Techniques in Home Winemaking, it has 29% sugar content. I am always surprised, and pleased when the two techniques agree.

There were dried grapes in with the crushed grapes. It would have had higher sugar content if I'd try to make it as a Rose'.
Now the wine is fermenting in the primary fermenter. I hope to transfer to glass in five or six days. I have taken to following the progression of fermentation by flavor. It is much easier than watching the refractive index change, and I don
