How long do hops keep fresh enough to use?

[TWS]

I've got two 1 oz bags of hops that have been refrigerated from day one and it is now seven months later. Can these still be used in my brewing? When do these expire?

as long as their green and not brown or tan yes, doesn't matter how long, otherwise toss them

I buy in bulk twice a year and keep hops at 34F, "I don't freeze unless its an exact amount" but you can freeze hops. they do not do well thawing out if unused, they are prone to mildew

Think about it this way. Hops are harvested once a year. So the hops you have are (hopefully) from the harvest last summer. So they are as fresh as the hops in your LHS, with the only difference being how they were stored.

Temperature and oxygen are the enemies.

Now days, with Australia and New Zealand in the hop business, you can find imported hops in the off season, so they could be fresher depending on the time of year, but only if they have been shipped and stored properly.

So to answer your original question, store them properly, and a year or more is not unusual.
