I just started drinking my most recent IPA, which I dry hopped AFTER cold crashing. I was tired of losing a significant amount of dry hopping flavor when it settled out with the yeast during the cold crash. I do ferment in conicals, so hop debris isn't much of a problem as it tends to all end up in the first bottle [usually a bomber]. Best damn IPA I've made to date, we'll have to see how quickly the hop flavor fades though.
