OK, I know these guys are the top of the heap, but I thought it was funny that they did a brew session with a dry hop addition and opened the bucket fermenter to add the dry hops. So, I am guessing that to open the bucket for a few seconds to add dry hops should not really impact the beer as much as I thought it would. I have a pale al working and I am going to do the same as they did. Open the bucket, drop the hops in and close it. I have a semi sealed transfer process so I think I will be ok. I have been doing it this way since I started all grain and it seem to be ok Rock on!!!!!!!
