Just an aside here but there are hops growing wild here along the edges of my fields and I have harvested a few of them, being careful to pick them while they are still mostly green so I don't get off aromas from them. In December I walked past a hop vine and the cones were all brown so I picked on to see what it would smell like being old. Hmm...I think I should have picked them to dry hop with as they smelled as fresh as the ones I picked and dried.
Now to the point, none of us can tell whether your hops are good, bad, or in between. Grab one of the ziplock bags and open it. Take a whiff. Smell bad? I doubt it but if it does, you should know what to do with it. I'm guessing you can't tell the difference between those and freshly packaged hops. Let us know what you find.
