Interesting, I thought you were getting the Fontana Green Apple Reisling. You and I may have to swap bottles when you are done.
Mine had no nutrient with it, and added the bentonite after adding the juice. And like yours, add the fpac all at the end. I bumped mine up to 1.082 to start.
All I know is my wife loves the stuff. It ended up around 1.018 after adding the fpac. ABV is around 11%.
