All,
I pressed a Cab at <1 Brix. No issues. It is still bubbling in the
carboys. There is quite a lot of gross lees in the bottom of the
carboys and I am concerned about H2S. Then again, it would seem that
the CO2 might carry the H2S off with it out the airlock. So, the
question is, do I wait till it is done fermenting so I don't end with a
slightly sweet Cab? Or do I rack now to avoid a potential H2S problem?

Thanks in advance!

Joe
