Ahhh, now I'm not hard core wine brewer, just kits, but I doubt they're required in any way. Once fermentation starts you'd be pushing up enough co2 to blanket everything in the carboy. And the time before that, for fruit wine brewers, I don't think is too long is it?
That'd be the only time you'd maybe consider it, while your campden'izing your fruit must, I'd wager.
But again, I only do wine kits from juices so I could be out to lunch.
