The thing is, I'm using older hops from last fall for this one. They're all sealed and have never been opened (besides my home-grown cashmere hops that I vacuum sealed in October). This was my current dry hop charge:
1oz cashmere flowers
The thing is, the centennial hops were a 2oz pack that I first opened up 10 days ago to add 1oz to the boil. I smelled them and they didn't smell amazing today. I had just stored them in a ziploc in the fridge since I figured 10 days can't really hurt them. I had a half opened bag of citra that was sitting in my freezer for over a year in a ziploc bag. I smelled them today and holy crap the cheese. I had never experienced that stench on hops before. Promptly threw them out.
My question is, if my 1oz charge of centennial had a slightly questionable aroma and I still added them, do you think it will significantly impact the final flavor and aroma of the beer? I wasn't going to add them, but figured screw it and did in the end.
I am also considering popping by my LHBS and getting 2 more oz of pellets as a second dry hop charge. These ones would sit there for 3 days and then I'd do an additional 2oz for 2 days before bottling. I was going to go with something fairly pungent like simcoe and citra to potentially mask any off flavor from the centennial.
Please let me know what you think. I'd hate for 1oz of hops to ruin what is quickly becoming my most technically accomplished beer!
