This is my first batch, made with honey from my bees I made a simple mead and a simple cyser 1 gal batches. I racked both to another 1 gal carboy 4 days ago. The mead I measured at 8% abv and the airlock is still bubbling,I'm gonna let it be. The cyser measured almost 14% abv and and the airlock doesn't have any pressure on it, no bubbles. My question is should I bottle the cyser now? There is a lot of headspace in the carboy. If I leave it will it turn into vinegar? Best bottle storage?
