I am going to be brewing a Session IPA that will have 6 hop additions. In addition to the bittering hops, flavoring hops and typical aroma hop addition it calls for and additional hop addition at 0 minutes which I assume is dunk the hop pellets into the wort and once they have expanded pull them out. The recipe then call for two different types of hops for a dry hop for the last 3-5 days of a secondary fermentation. I want to make sure. I am pretty sure I would need to sanitize (by boiling) any hop sacks that I would use? Can I add the hops into the carboy then rack the beer over them or should I rack the beer then add the hops or does it make any difference? I am an experienced extract brewer but have never done a beer with this many additions or a dry hop.
