Hop shelf life question

Considering buying an 8 oz package of pellet hops to use over the next 6 months or so instead of buying just the 1 oz package. My question is can these be opened then stored in the refrigerator and remain fresh/ usable ?

Thanks

 

Store in a sealed zip-loc freezer bag, in the freezer. Evacuate as much air as you can, or use a vacuum storage container.

 

Thanks. How long do you think they would last?

 

I have some EKG I bought 2 years ago, still in great shape. I use a food sealer thing, sucks the air out, and heat seals the bag again. They have also been kept in the Freezer the whole time...

 

Hops in freezer can last for years depending on how well they are stored as everyone else has mentioned above. Also one other thing to think about is over time no matter what hops will lose alpha acids. A calculator like this will help you know exactly where you stand if you are trying to hit a certain IBU. 11% alpha acid won't be 11% in 2 years. At least that's how I understand it.......if you even care about this

Edit forgot to add the calculator http://www.brewerslair.com/index.php?p=brewhouse&d=calculators&id=cal16
