Thanks all! That's what we did yesterday... thank goodness we had an empty carboy. Sterilized it, poured it in... when there was about an inch left, we "swooshed" the bottle. We lost a bit of liquid though, it seems..
It only filled about half a gallon carboy. There's what looks like two small chunks of apple skins floating around in it, which probably has a little something to do with it's spontaneous fermentation.
We'll see what happens come spring!
