I dont get topping off. You dont fill a gallon jug real full to allow space for fermentation. But then after you rack it, the volume drops even more. As it clears, I have read you need to keep the level up to the shoulder of the jug. I have read about topping off with concentrated grape juice etc. Doesnt that all change the sugar content of the wine? or water doesnt that water it down? If I making elderberry for example, doesnt the grape juice change the taste? I would think that adding water would dilute it. What do most people do? I read about the marbles, maybe that is the way to go. I have also talked to a guy that doesnt worry about the air space. How much will just leaving the air space there effect the wine?
thanks a bunch in advance.
