Hi!
I have 30 litres of cider which seemes to have finished fermenting (was down from more than a bubble a minute at the start through the airlock to less than one every five minutes). I cracked open the bucket to test it a couple of days ago. Test test (very dry) and specific gravity measures confirmed that close to all the sugar was fermented. I siphoned off a couple of litres and closed the lid again, planned to rack if off into a demijohn for maturing, once I'd got hold of one.
A couple of days after that, it has started bubbling a lot again, more than once a week. Given that all the sugar was gone, I am really paranoid something got in and is turning the alcohol to vinegar. Is that likely? What I hope happened instead is that the sediment (which is thick) got stirred up and more sugar was put into solution. How do I know which happened and what can I do?
Cheers,
Ben
