Inert wine gas during bottling?

[Nazhuret]

I've never used the stuff but you all know about the gas canisters you can get to lay a blanket of inert gas on top of an open bottle of wine.

Could this be used just before corking / capping when bottling?

What would be the advantages / disadvantages in doing so?

Yes it could and it would be expensive. Unless you are an absolute fanatic about de-gassing your wine, there will be a little CO2 left. This CO2 will come out of solution and fill the head space during the bottling process. In any case, unless you are using plastic corks, some air will leak into the bottle during the aging process.

I used to work at a winery... we injected nitrogen into the bottles right before filling them.
