Just to update.
I racked to secondary this weekend and had some left over. (Still getting a handle on my different carboy sizes.) I was forced to drink the leftover and it was great. This is my first fruity wine and I liked it better than I thought. Although I drank it at room temperature, I think it could use some chilling. Now I have the incredibly long racking time of two weeks to wait before bottling. Might have some left over again, which would be just too bad.
Added 7-1/2 cups sugar and 1/3 of the Fpack upfront. Still a little sweet for me, but tolerable. I'm guessing you need the sweetness on the quickdrinkers.
