I am frequent dry hopper. Something that I always do that I learned in my days of commercial brewing is to "surface sterilize" (for lack of a better term) the hops. I basically bring a pot of water to a boil, drop the hops in, and essentially nuke any nasties, before adding to the secondary. Then Iput the hops in the carboy, and let the hops cool before racking on to the hops. At the brewery we would place the hops into a bag, place the bag in a grant, and run boiling water over the bag for a few minutes before adding to the secondary.
After doing this 50+ times at home, I began to question if this is necessary. Any thoughts, pro or con?
