Are people adding dry hops in multiple, separate additions? I've been told to be wary of leaving dry hops in for more than 7-10 days, but also keep hearing about breweries with "complicated dry hop schedules". Do people add, then remove, then add something else? If so, how do you remove from a carbuoy? I've always just added one bag of hops a week or two before bottling. Any wisdom here is much appreciated.
