Assuming the wine was dry when you racked, it would have contained
about 10.6%ABV. Adding the grape juice would have caused about
a 10% dilution leaving you with about 9.5%ABV presently in the wine.
Barely adequate. The added sugar may cause the ferment to
restart, so leave it under airlock for a while to see.
