I brew beer so I have (2) 6.5 gallon glass carboys. I have heard that using
a 6.5 gallon carboy is not recommended because of the .5 gallon of head
space but wouldn't the escaping CO2 keep the wine from being oxidized?

The reason I ask is that I do not want to purchase a 6 gallon carboy
specific to wine making because I will not be doing it that much especially
since I already have similar equipment from beer brewing.

Thanks,
