I know that how long a given hop lasts depends on its stability and how it is stored. For example, I've read that centennials have poor stability, meaning that , they will not last as long as other types. I also know that if I expose them to light, air, warmer temps they will go bad faster.
However, just how long will my whole-leaf centennials last? Weeks? Months?
They are in a vacuum sealed pack from freshops.com, and they are in my freezer in the box they were shipped in.
I'd love it if anyone has a link to just how long centennials, in whole-leaf form stay good for. They are from this year's crop, btw. I also bought some chinook and some amarillo. I wonder how long those will last as well.
Final Question: How do you re-seal a vacuum sealed bag?
Some of my hops were shipped in a six ounce bag. I obviously do not want to use all six ounces at once. However, in the past, I've opened up a vacuum-sealed bag of simcoe and used it in the boil. I then sealed it as best I could, but couldn't figure out how to return it to a vacuum sealed environment. When I took them out after two weeks to dry hop, they had gone bad--I got that Parmesan cheese smell and they looked brown.
