As I don’t use the #3 and #4 packs, my clarifying and stabilizing takes quite a bit longer.
Instead of an airlock, I use a plastic stopper with the valve part of a Vacu-Vin on it. I pump this up at least once per day until I no longer get any bubbles coming to the surface. This typically takes anywhere from 1-3 weeks. After 2 weeks, If I am still getting alot of bubbles, I rack the wine again, leaving as much sediment behind as I can. I have found that when I do this I can usually get the last of the CO2 out in a matter of days.
Right now, I will be racking this batch in the next day or 2 as I am still getting a fair amount of CO2 forming.
