You should be ok with that. Unless you are talking a big tank, the
inert gas route is probably a better way to go anyway. Most wineries
can't keep things topped up all the time so use inert gas for the
headspace. Iversen recommends it; I've seen it recommended in most
commercial winemaking books also. Argon seems to be the gas of
choice, it's heavier than air, nitrogen and CO2 also. I don't think
it likes to stay in solution in wine either; I think people like to
use it to purge the wine of CO2.

If I ever decide to get rid of my carboys and go with SS I will be
doing this too.

Regards,
Joe
