When you get gym socks, they are old and past prime condition. With most hops they follow a progression of fresh bright aromatics, these fade and spicy notes come out. Next is the cheese, body odor and gym socks, last comes hay/straw mixed in with body odor (lambic stage). You will find the bright floral notes in Saaz such as Lilac, bright fruits in American and Southern hops such as melon and peach fade quicker with age than the resinous, "hoppy" and citrus notes.
Many Nobel hops (True nobles, not Yakima Chief remarketing American hops) do not do well when rubbed, their aromatics are not full in your face like Chinook (one of the prettiest hops to rub), Citra or Mosaic. They tend to be restrained. I think one of the worst when rubbed is Saaz, if I never made a Saaz beer before, I sure would not start after rubbing them
Off putting notes that I have found are that the hops seem muddled, not bright clean and vibrant. Much the same way Christmas beers can be out of balance from one spice that does not play well with the rest of the flavors in a beer. The result is, I have been avoiding dry hopping in large amounts with most noble hops. I make sure I use some throughout the beer and will get all my bitterness from these low alpha hops. I think it gives better beers most of the time. With that said, every time I draw a line in the sand about brewing, yeast, hops, malt, techniques, along comes a beer that is delicious, using the techniques, or ingredients that I think are wrong and yelling at me I still have a long way to go to earn the title brew meister
Ncbrewer repeated gym socks from noble and Fuggles is a concern, neither should have these characters. Look at your storage, cold is better, colder even better. If you opened the pack and they smell that way, talk to your supplier, they need to know they have junk. Coming from the supply side, heck of a hop year. Hop harvest was halted for windstorms that knocked down hop trellises, blow hop bines off the picking machines and caused smoke to be so thick the farmers could not see to pick hops. More preharvest stress than in the last 20 years for Northwest hops. Many are drop dead tasty with all the issues. I am attaching a storage guide that should help you keep the gym socks at bay
