I am by no measure an expert on this, however, when I have headspace issues after racking I flow CO2 into the carboy and then install the airlock.

If you've got CO2 on hand, bonus, it's another highly recommended method on the list of things you can do about headspace, but we don't always mention it to new-bees because not everyone has a CO2 tank kicking around to flush out their headspace. :)
 
I invested in extra carboys, You don't have to get them all at once. Get a 3 gallon this month & next month get a 6 gallon. Also, Buy a 1.5 Liter bottle of wine & keep the bottle. The mouth on that bottle is big enough for a drilled stopper.

That's what I'm doing, getting a 3 gal one this payday. I've got lots of one gallon and three liter carboys, ready for bigger ones!!8)

I do and haven't used it yet. For mead production. I need to break it out.:cool:
 
Is it wrong that I use a mixture of Argon and CO2 to blanket my mead? Yes, it's welding gas. I have it on hand and it's inert. ;)

Does that make all my meads wierdomels? Or weldomels?
 
Argon or Argon/CO2 blends are actually even better than CO2 alone for blanketing purposes, since Argon will not dissolve into your mead. The only issue I might have with welding gases is their purity. Although they should be virtually identical to the medical or food grade stuff (since most gas distributors essentially fill tanks from a common source), medical and food grade gases are certified to a certain level of purity.
 
Wayne, I asked my gas supplier about that. It earned me an odd look, but he assured me of the purity of the gas; it's necessary to the purity of the weld.
