How do I know when my wine is degassed and ready for the fining agent to be added? The instructions that came with my kit say it should be degassed by now but ive noticed (espcially when I stir it) that there is still just a little bit of action in the airlock. Is it safe to add the fining agent? Also, will the fining agent alone be good enough to clear up my wine or do I need to filter still?
