I'm making a one gallon batch of wine from fresh grapes which is now bulk aging and will continue to do so for a few months. One reason among others is to let it naturally degas. My assumption is the CO2 would escape via the airlock however there is no movement in the water in the airlock. Am I missing something as to what happens with the CO2? The water isn't level due to the initial pressure from attaching the airlock so there are no leaks.
