Out of date hops

[bobukbrewer]

I have some Progress and Aramis hops, 2015 harvest, use by date September 2018. They have been stored at room temperature. If say 20 gm boiled for one hour contributes 10 IBU how much "extra" should I use as they are old. My gut feel is 100% more but maybe someone knows better.......

Some hops store better than others. Strisselspalt is probably a good substitute for aramis in the calculator.

I have done the calculation assuming very fresh hops - so I am asking if anybody has experience of this issue....

I've still Have hops that are two years over UBD, and they are still lovely and aromatic uses some on my recent brew to no problems so far, store them in vacuum type seal jars, cheap as chips in Wilko
