My first big effort is a Shiraz kit. I racked it when the sg was below
1.040 as the kit said, and topped off the carboy, as one book I read said
"after this point oxygen is your enemy . . ."

Well, the cork blew off the carboy.

Any suggestions about carboy level at the first racking would be helpful.
If I top it off when I rack again, regardless of sg, am I going to have wine
all over my floor?

Thanks.
