I have some pineapple wine in a primary bucket. It is time to transfer it to a carboy. Unfortunately I just realized that all 5 of my 5 gallon carboys are full at the moment. I have a four 6.5 gallon ones that are empty but I am worried about the head space. Will there be enough CO2 to minimize the risk? the fermentation is still pretty active.. I will be bottling from one of the 5 gallon carboys in a few days and can transfer it again if need be at that time.
