How long is it safe to assume they're good in the fridge in a zip lock bag? Is two weeks safe? I've had some in the fridge for a week that I want to use next weekend. They're already stinking up the fridge which got me wondering. Id be happy spending a few bucks for new hops if there's any chance these would be bad already and ruin a batch.
Are they stinking in a bad way? If you mean that the fridge just smells of grassy hops, they should be fine to use. Best thing though, is to put them in the freezer. Even if you just put them in a ziplock sandwich baggie and squeeze out as much air as you can, they should still last 6 months in the freezer.
