I have my wine in the second fermination now (in two 1 gallon jugs). However for last few days I was seeing water in both airlock going in wrong direction. To prevent it getting sucked in, I reset the airlock few times. However I don't understand why it would do this, expecially since a day or two ago both airlock were slowly bubbling some air out.
Its my first time trying to do wine so can anyone tell me if I should be worried?
