I added 1.5 oz of centennial right at the start of an IPA primary fermentation. In hindsight I see (and smell!) that I should have waited until after active fermentation was done. I love heavy hop aromas and fear I've lost most from the initial fermentation. I am considering opening back up to add another 1 oz in the "primary" (same vessel after active fermentation is done)...wanted to avoid moving to a secondary. Any thoughts?
