Anyone use inert gas in their carboy? I have a 6gal and a 6.5gal carboy
that won't be able to fill with wine when I rack it. Store guy
suggested I get a 6.5gal. That's a lot of air space and I don't want to
have to add that much water or similar wine. I was thinking of using
the inert gas that they sell to fill the space.

Anyone using it? Is it worth it or should I get a 5gal.

Thanks,

Marty
