As we don’t include finings in any of our cider kits, we don’t clarify prior to bottling as some yeast is required in the bottle for secondary fermentation (for carbonation).
There is no need for fining aids while clarifying in the bottle, this should happen naturally over the course of 1-2 weeks without them. Finings can hinder the bottle carbonation if added.
We wouldn't recommend adding finings unless the cider is being kegged, and in that case, it's best to add them at the end of fermentation with the flavouring.
