So I have approx 15 gallons of cider, it just finished its primary ferment and later today I'm going to rack it to my secondary carboy. I was woundering since I'm going to be kegging this batch and force carbing it, could I add potassium sorbate and a few campden tablets when I rack it. I usually rack my ciders 3 or 4 times for clarity but I figured if I add the sorbate and campden now I might not need to rack it a 4th time, what does every body think.
