I have tried various methods of dry hopping. So far all are a great disappointment. I have loose hopped in secondary, bagged in secondary, hop ball in corney. No hop aroma like Lagunitas or Head Hunter. (My favorites -I want to smell that goodness) Luckily I save these and re-use as bittering in new brews. Will try one more thing. Hop Randal between keg and Perlick. Any thoughts? Been brewing now about 16 years. Cheers
