I am severely new to wine making and have many DIY web sites on the topic that are extremely advanced, snobby and never offer the same results. I really just want to know does the "cap" I think its called (the fruit mash floating on top) does it have to sink for the wine to be done? I tasted a bit from a siphon tube today and it has a good flavor and an overly high alcohol content but is still producing Co2 and the cap is still floating. How Do You Know When Its Right? Any help would be awesome. Thanks.
