Title: Old Hop calculator
Post by Richard G on Apr 3rd, 2015 at 8:27pm
Storing hops in a freezer does extend their life and will not damage the hops. When hop processors store hops, they store them at temperatures ranging from 20–30° F and keep them in this temperature range until they are sold. If the hop variety has good storage properties, and if it is packaged properly, hops will remain fresh for two to three years. Most pellets are vacuum packed to minimize oxygen in the package as oxygen will seriously affect the hops

How to store hops-
Good - At a minimum, keep hops in the refrigerator in an airtight container and use them as soon as possible after purchasing.
Better - Even better, keep hops in a vacuum-sealed package in the refrigerator. A consumer grade vacuum sealer can come in handy for this purpose.
Best - The best way for storing hops is to keep them in an air-flushed, vacuum-sealed package in the freezer. Most homebrewing hops these days are packaged  and stored this way. If it will be more than a few days before brewing with the hops, just toss them in the freezer until brew day.

If your have been storing your hops in the freezer in an airtight container for less than a year, you should be able to use these them without their age having a negative affect on your beer.

If the hops have been stored for longer than a year or just kept in a refrigerator, it might be a good idea to calculate the actual alpha acid content of the hops. All hops should be packaged with an alpha acid content expressed as a percentage. From there, it’s a simple matter of using an aged hop calculator Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register to adjust the alpha acid content and the weight needed to achieve a desired bitterness level.

Keep in mind that there are many factors affecting bitterness in beer, so calculated IBUs are just an approximation. At the end of the day, it may be worth just buying some fresh hops so you can be sure you get the best qualities from your hops as possible.
