So I'm new to extract brewing and I have read recipes described boiling with the entire extract for 60 minutes. I was talking to a few people, and they were suggested waiting until about 15 minutes to end boil before adding my extract to avoid crystallization of my sugars. I'm trying to improve a very hoppy yet dry IPA, so I was wondering if this was the case. Should I wait till later? Others mentioned adding a couple cups of extract up front and the rest at 15 min. Will any of this affect my hot break or does that not matter with extracts? Ant input is appreciated.
