Yep, as Mr Blue said, you have to wait until there is no airlock movement, then leave it another week. Rack it to a fresh demijohn and don't worry too much if you suck a bit of the yeast in, shake out the fizz, add Campden and sorbate and after a a couple of days to a week it'll be ready. It will stay completely cloudy and not clear, though this is pectin not yeast keeping it cloudyI've started off a batch (my first) off last night using this recipe. Quick question though... How do you know when it's ready to move to another demijohn as it's always going to be cloudy? Or have I misunderstood?
It takes about 4 weeks start to finish in the summer, so allow a couple of extra weeks this time of year
