I just racked my first cider to secondary and I have quite a bit of head space in my carboy as it is 6.5 gallon and I have about 4.5 gal of cider in there. Primary fermentation was nearly done before I racked it over, I was hoping to do it just before primary fermentation completed to get a bit of co2 to build up a blanket. Since I racked it the air lock bubbled once and I think that is all. Should I be worrying about oxidation? My friend told me to drop a small chunk of dry ice in it to build up co2 blanket. I hadn't thought of that but still weiry of dropping chunks of anything into my cider. Besides my friend knows less about home brewing than I. any thoughts or insite would be appreciated.
