Hi

I started two batches of red wine the other day and put them behind a chair
which was pretty close to a radiator. Had a look today and one of the tops
from the air lock had been forced off and wine had come out.

Q) with no air lock in place for possibly a couple of days is there a
problem with the wine?

Secondly

I started another new batch yetserday, which makes 4 demijohns on the go, 3
are frothy but one has no froth at all but the air lock still shows signs of
bubbles passing through it, (this is not the same bottle as above), is this
fermenting properly?

Thanks
