I made my first DIPA with all Citra hops.
After about a week in primary, I transferred the beer to a keg, added a little hop sock and added 1oz of Citra. Left it that way for another week and then transferred to another keg which I then force carbonated. About a week later, I started drinking the beer and it was delicious. About another two week later, I had a beer and it didn't taste at all what it tasted like when I drank it at first. Quite a bit of the bitterness and aroma disappeared.
I checked all the normal stuff - Cleaned the Tap and beer lines etc. I even at a point shook the keg to get all of the 'stuff' that fell out back in suspension again, but this only slightly helped get some of the aroma back (not sure if this was just in my mind though).
I want to make sure you understand that I don't think this was any sort of infection. There was no indication of this, no other off-flavours nothing -
Has anyone experienced this?
Possible useful information: The hops was vacuum sealed and stored in my freezer for more than a year.
