ALWAYS use metabisulfite solution in your airlocks and change it once a month. Keep bungs spotlessly clean too.

Keep all these wines as they are for at least 4 months before any racking. The CO2 blanket is good enough if the temperature is constant. You don't lose much if you quickly change the airlock for a clean one.

Rack, then add the recommended amount of metabisulfite to each and beat well and let sit another month. (want 50ppm SO2 here)

I would get 2.5 FULL carboys out of each white type. In fact, I would blend the two part carboys to have a table white. I would rack once more after a month and bottle (unless fining is really required).

Look at the clarity of the wine in a glass when you rack, and this will tell you how long to hold and whether you would fine (isinglass is my choice).

The reds might want another 2-3 months, but those carboys would need to be filled as full as possible (you would hold these as full as possible, even to using a half size carboy). Then you can see if they need fining as well as one more racking before going into the bottle. Again, I would choose isinglass unless I saw some good reason to do otherwise. Sparkolloid works OK after isinglass if it is needed.

The less you handle good wine, the better. This information came to me from a winemaker with years of experience and I have found it to be the best way to think about winemaking. I learned to rack carefully and eliminate the need for fining unless there is a lot of oak chips, or some other reason to fine.
