I have a batch of blackberry wine that I would like to stabilize now to get
the alcohol content and sweetness I desire. I was going to hit it with a
Campden tab, potassium sorbate and maybe Isinglass or Chitosan to help it
clear. Is this what you would do?

Also, my local brew store is closed until tuesday, I would rather stabilize
now not wait until tuesday. I have the Campden tabs but not the rest, any
other place to get this stuff?
