We just poured it in and it worked perfect. Just tasted a Blackberry Merlot that we racked into the carboy for it's last 14 days. Did the same to it with the 7.5 C sugar and it is YUMMY! Probably accounted for the difference in SG but it turns out great so we aren't going to mess with it. Good luck! You will be drinking yummy Green Apple Riesling before you know it!
