Hello all, Ive got a little three gallon carboy Im using for cider. Its about the right size for me as Im primarily making beer. However, Im curious if most people consider it okay to use plastic beer fermenters with cider. Ive got a five gallon Better Bottle which is used as a beer secondary for dry hopping and such. Im wondering if it is possible to use it as a primary for a small batch of cider and then transfer the batch over to the glass carboy after the main fermentation to clear? My main concern would be any lingering beer odors effecting the cider or the cider effecting the beer when its used as a beer secondary. Also, if most people dont see it being an issue, would three gallons of cider in a five gallon primary result in too much headspace? I tend to think not for primary purposes, but wasnt sure.
