Default How Long Do Whole-Leaf Hops Last?

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.

Default How long do they last?

Simple answer...Not very long at my house.

They should be frozen and kept air tight bag

Reseal a vacuum sealed bag with a vacuum sealer.

Properly vacuum sealed and frozen, they should easily last a year or two. I've never kept hops longer than that, but they should last even longer than that.

I was thinking about this the other day. I have an ounce of Simcoe plugs from 2006 that have been in my fridge for a few years and I looked at them the other day and they seemed fine. I think I might use them for bittering...I think if kept in a vacuum sealed bag in the fridge/freezer they will last indefinitely. I don't think I'd use them for aroma though.
